Well-Architected Framework (WAF).
BLUF: 5 guidelines to produce high-quality, stable, and efficient cloud architecture.
Guidelines: (5)
Reliability: The workload is resilient (withstand, recover quickly) and available.
Security: [Security Documentation, Policy & Controls] Throughout the Application Life Cycle (ALM), from design & development, [Security], and implementation, to deployment, and operations (DevSecOps).
Cost Factors & Cost Optimization: Focus on generating incremental (increase) value early using a “Build-Measure-Learn” feedback loop to gain measured customer reactions, learn, and adjust (Pivot) to improve customer interactions.
Operational Excellence: Keep Operations, Production, Processes, and Applications running. Do audits and QA/QC using a “Maturity Assessment Plan” (aka Checklist).
Performance Efficiency: The workload can scale (to increase or decrease) to meet user demands efficiently.
Secure & Audit the Cloud Architecture (for Impact Level 5-IL5 Data) -- using Azure.
BLUF: Secure & Audit the cloud architecture in a government cloud environment, especially for Impact Level 5 (IL5) data, requires "A Multi-Layered Approach."
Steps to Ensure "Compliance" (to "Audit") with Industry Standards and Regulations: (5)
Leverage Built-in Security Features:
Azure Government Offerings: Azure Government (Environment) is a separate cloud environment specifically designed for US government agencies and their workloads. It adheres to stringent compliance regulations and physical isolation from the public cloud.
Security Defaults: Utilize Azure Policy and Azure Security Center to enforce security best practices and configurations across your cloud resources. These tools can help automate security baselines and continuously monitor compliance.
Identity and Access Management (IAM): Using Azure Entra ID (aka Azure AD) for centralized identity and access control. Enforce strong authentication protocols like Multi-Factor Authentication (MFA) for all access.
Secure Network Design:
Virtual Networks (VNets): Create logically isolated Azure VNets to segregate (isolate) resources based on security needs. Implement Azure Network Security Groups (NSGs) to control inbound and outbound traffic flow within the VNets.
Private Endpoints: Restrict data exfiltration (a security breach) by using Azure Private Endpoints to allow your VNet resources to securely access Azure services without traversing the public internet.
(EXTRA) Boundary Protection: Additional network layer protection at the entry point to your cloud environment. Consider deploying a DISA Secure Cloud Computing Architecture (SCCA) using a Boundary Cloud Access Point (BCAP).
Data Protection and Encryption:
Data Encryption: Encrypt all "DATA AT REST" and "DATA IN TRANSIT" using industry-standard encryption algorithms like Azure Key Vault to manage and control cryptographic keys.
Data Loss Prevention (DLP): Implement Azure Information Protection (AIP) to classify and protect sensitive data by restricting unauthorized access and data exfiltration attempts.
Activity Logging and Auditing: Enable comprehensive activity logging for all resources and user activity within your cloud environment. Utilize Azure Monitor for centralized log collection and analysis to detect anomalies and potential security threats.
Compliance and Regulatory Framework:
NIST Compliance.
NIST Security Controls.
CISA Compliance (Cloud Security Technical Reference Architecture).
ZTMM; PQC...
CISA's Cloud Security Reference Architecture v2 -- https://www.cisa.gov/sites/default/files/2023-02/cloud_security_technical_reference_architecture_2.pdf
FedRAMP High Baseline: Ensure your cloud environment adheres to the FedRAMP High baseline for securing government data. Microsoft Azure Government is FedRAMP High compliant, but you'll still need to implement additional controls to meet specific agency requirements.
DISA SCCA Compliance: For IL5 data, consider following the DISA's Secure Cloud Computing Architecture (SCCA) guidelines which provide a framework for securing sensitive workloads in commercial cloud environments. -- SCCA Guidelines (3): (1) Standardized Approach: SCCA offers a standard way to secure cloud environments for Impact Levels 4 and 5 data, the two highest classifications for sensitive DoD information. (2.0) Focus Areas: It addresses security at two levels: (2.1) Cloud Access Point (CAP): This acts as a secure gateway, controlling access to the cloud and protecting DoD networks from cloud-based threats. (2.2) Virtual Data Center Security Stack: This additional layer safeguards applications and data residing within the commercial cloud environment. (3) Cloud Agnostic: SCCA applies to Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) offerings from various cloud service providers (both on-premises and off-premises).
Continuous Monitoring and Improvement:
Security Vulnerability Management: Regularly use Azure Security Center to scan your cloud resources for vulnerabilities or other vulnerability scanning tools. Patch identified vulnerabilities promptly to minimize the attack surface.
Penetration Testing: Conduct periodic penetration testing to identify potential security weaknesses in your cloud environment and remediate them before they can be exploited by attackers.
Security Awareness and Training: Regularly train your staff on cloud security best practices and procedures to ensure they are aware of potential threats and can contribute to a strong security posture.

BLUF (3): (1) Shadow Access refers to unauthorized, unmonitored, and often excessive access to cloud resources like applications, data, and networks. (2) This lack of visibility creates security blind spots, making it easier for attackers to exploit these unintended access points. (3) It arises due to the increasing complexity of cloud environments with:
Automated account creation: identities for users and applications are (accounts) created automatically, making it difficult to track permissions.
DevOps practices: Faster development cycles can lead to temporary access becoming permanent or overly permissive.
Cloud-native architectures: The interconnected nature of cloud services creates hidden access pathways.
Shadow Access vs. Zero Trust.
Zero Trust is a security model that assumes no user or device is inherently trustworthy. Every access attempt needs verification regardless of location or origin.
Shadow Access directly contradicts Zero Trust principles by granting unauthorized access that bypasses security controls.
Steps to Mitigate Shadow Access Risks: (4)
Identity and Access Management (IAM): Implement a strong IAM solution to centrally manage user and application access. This includes enforcing least privilege principles (granting only the minimum permissions needed).
Regular Reviews: Conduct periodic reviews of user access and entitlements to identify and remove unused or excessive permissions.
Multi-Factor Authentication (MFA): Enforce MFA for all access attempts, adding an extra layer of security beyond passwords.
Cloud Monitoring: Utilize cloud provider monitoring tools to track access patterns and identify anomalies that might indicate Shadow Access.
Azure Resources to help combat Shadow Access. (4)
MS Entra ID (aka Azure AD): Centralized identity and access management (IAM) & MFA for Azure resources and other cloud applications.
Azure Monitor: Provides comprehensive logging and monitoring capabilities to track user activity and identify suspicious access attempts.
Azure Conditional Access: Enforces additional access restrictions based on factors like location, device, or time of day.
Azure Sentinel: A cloud-native SIEM (Security Information and Event Management) tool that aggregates security data from various sources to detect and respond to threats, including Shadow Access attempts.
Before Zero Trust (ZT).
BLUF: The dominant security model relied on a castle and moat approach, often referred to as a perimeter-based security model. -- Here's how it worked (2): (1) Focus on the Outer Edge: Security design prioritizes the external perimeter of the network, typically protected by firewalls and intrusion detection systems. (2) Trust Once Inside: The assumption was that once someone gained access to the internal network (like an employee), they were considered "trusted" and had relatively unrestricted access to resources.
Limitations (3): (1) Increased Attack Surface: With the rise of cloud computing and mobile devices, the traditional network perimeter became less well-defined. Attackers could target vulnerabilities outside the perimeter to gain access. (2) Insider Threats: Traditional models didn't adequately address the risk of insider threats, where authorized users misuse their access. (3) Data Breaches: Even with a strong perimeter, a successful breach could grant attackers access to a vast amount of data.
Zero Trust (ZT): ZT assumes no user or device is inherently trustworthy and requires continuous verification for every access attempt. (my kids said, ZT is a computer that has amnesia).
Before Post-Quantum Cryptography (PQC).
BLUF: The field of cryptography relied heavily on a set of well-established mathematical problems for securing communication and data. These problems were considered difficult, if not impossible, to solve with traditional computers within a reasonable timeframe. This traditional approach is often referred to as pre-quantum cryptography.
~ Note-1: The emergence of quantum computers poses a significant threat to pre-quantum cryptography. Shor's algorithm, a theoretical algorithm designed for quantum computers, can efficiently solve the problems that underpin these traditional algorithms, rendering them vulnerable.
~ Note-2: The development of PQC is a proactive response to this threat. PQC algorithms are designed to be resistant to attacks by both classical and quantum computers, ensuring continued secure communication and data protection in the age of quantum computing.
Pre-Quantum Era:
Public-Key Cryptography: This branch of cryptography uses algorithms like RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) which rely on the mathematical hardness of problems like integer factorization, the discrete logarithm problem, and the elliptic curve discrete logarithm problem.
Security Assumption: The security of these algorithms stemmed from the assumption that solving these problems would take an infeasible amount of computing power with classical computers.

Onboarding Devices and Enabling Next-Gen Protection (Antivirus/Anti-malware).
Utilizing Endpoint Detection and Response (EDR) for Incident Response. -- BLUF: This scenario focuses on leveraging MDE's EDR capabilities to detect, investigate, and respond to advanced threats that might have bypassed initial prevention mechanisms.
Implementing Automated Investigation and Remediation (AIR) -- BLUF: This scenario focuses on automating the investigation and remediation of common threats, reducing the manual workload for your security operations center (SOC).
Implementation Steps. (3-Large Steps)
Onboarding Devices and Enabling Next-Gen Protection (Antivirus/Anti-malware). (3)
Prepare your environment:
Verify licenses: Ensure you have the necessary MDE licenses (e.g., Microsoft 365 E5, Defender for Endpoint Plan 1 or 2).
Network and proxy settings: Configure your network and proxy settings to allow communication with MDE cloud services (e.g., *.security.microsoft.com, login.microsoftonline.com).
Permissions: You'll need Global Administrator or Security Administrator roles in Microsoft Entra ID (formerly Azure AD).
Choose an onboarding method: MDE offers several methods to onboard devices, depending on your environment and existing management tools. The most common are:
Microsoft Intune (recommended for modern device management):
In the MS Intune admin center (intune.microsoft.com), navigate to Endpoint security > MS Defender for Endpoint.
Ensure the "Connect Microsoft Defender for Endpoint to Microsoft Intune" toggle is set to On.
Once connected, you can create Endpoint security policies in Intune under Endpoint security > Antivirus or Endpoint security > Attack surface reduction to configure MDE settings like real-time protection, cloud-delivered protection, and attack surface reduction rules. Assign these policies to your device groups.
Group Policy (for on-premises Active Directory environments):
Download the MDE onboarding package from the Microsoft Defender Portal (security.microsoft.com) by going to Settings > Endpoints > Onboarding.
Select your operating system and deployment method (Group Policy).
Follow the instructions to deploy the onboarding script via Group Policy to your devices.
Use Group Policy Objects (GPOs) to configure Microsoft Defender Antivirus settings (e.g., real-time protection, cloud protection, exclusions) under Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus.
Configuration Manager (formerly SCCM):
Integrate Configuration Manager with MDE by enabling the "Microsoft Defender for Endpoint" connector in your Configuration Manager console.
Use Configuration Manager's Endpoint Protection features to deploy the MDE client and manage its settings.
Local Script (for a few devices or testing):
Download the onboarding package (PowerShell script) from the Microsoft Defender Portal as described for Group Policy.
Run the script manually on individual devices.
Verify onboarding and next-generation protection:
In the Microsoft Defender Portal, go to Endpoints > Device inventory. You should see your onboarded devices appearing here.
Check the "Health state" and "Antivirus status" columns to confirm that devices are onboarded and running the Defender Antivirus effectively.
Simulate a test detection (e.g., by downloading the EICAR test file) to confirm that real-time protection is working.
Utilizing Endpoint Detection and Response (EDR) for Incident Response. -- BLUF: This scenario focuses on leveraging MDE's EDR capabilities to detect, investigate, and respond to advanced threats that might have bypassed initial prevention mechanisms.
Ensure EDR is configured and devices are onboarded: (2)
Confirm that devices are successfully onboarded to MDE (as per the previous section). EDR capabilities are automatically enabled when devices are onboarded to MDE Plan 2.
Ensure Endpoint Detection and Response (EDR) in block mode is enabled in the Microsoft Defender Portal (Settings > Endpoints > Advanced features). This allows MDE to block malicious activities even if Microsoft Defender Antivirus is running in passive mode (e.g., if a third-party antivirus is active).
Monitor incidents and alerts: (3)
In the Microsoft Defender Portal, navigate to Incidents & alerts > Incidents.
Review the list of incidents. An incident groups related alerts from different devices and sensors to provide a holistic view of an attack.
Select an incident to view its details, including the affected devices, users, evidence, and attack story (a visual representation of the attack chain).
Investigate and respond to threats: (4)
Analyze the attack story: Understand the sequence of events, what processes were launched, files created, and network connections made.
Examine evidence and entities: Review the files, processes, IP addresses, and users involved in the incident. MDES provides rich context and threat intelligence for each entity.
Take response actions (7): From the incident or device page, you can perform various response actions:
Isolate device: Disconnects the device from the network (except for MDE communication) to contain the threat.
Run antivirus scan: Initiates a full antivirus scan on the device.
Collect investigation package: Gathers forensic data from the device for deeper analysis.
Consult a threat expert (if licensed): Engage Microsoft's security experts for guidance.
Initiate live response session: Establish a remote shell session to the device for manual investigation and remediation.
Contain/block files: Mark malicious files as blocked to prevent their execution across your organization.
Suspend user: Suspend the compromised user account in Azure AD (if integrated with Defender for Identity).
Utilize Advanced Hunting (for proactive threat hunting):
Go to Hunting > Advanced hunting.
Use Kusto Query Language (KQL) to write custom queries to search for specific threat indicators, behaviors, or vulnerabilities across your endpoint data. This allows you to proactively identify threats that haven't triggered an alert.
Save custom detection rules based on your queries to get alerted on future occurrences.
Implementing Automated Investigation and Remediation (AIR) -- BLUF: This scenario focuses on automating the investigation and remediation of common threats, reducing the manual workload for your security operations center (SOC).
Configure automation levels for device groups:
In the Microsoft Defender Portal, go to Settings > Endpoints > Permissions > Device groups.
Create or edit device groups based on your organizational structure or risk levels (e.g., "High-risk servers," "Executive laptops").
For each device group, set the Automation level.
Full - remediate threats automatically (recommended for most environments): MDE will automatically investigate alerts and take remediation actions (e.g., quarantine files, stop services) without requiring manual approval.
Semi-Full - require approval for certain actions: MDE will perform some automated actions but require approval for more impactful ones.
Partial - require approval for all actions: Automated investigations will run, but all remediation actions require manual approval.
~ Note: Automated investigation is enabled by default. The "Automated investigation" setting in advanced features has been deprecated as it's now always on.
Review and manage remediation actions in the Action Center:
Once AIR is configured and alerts are triggered, MDE will generate automated investigations.
In the Microsoft Defender Portal, go to Action Center.
Pending actions: This tab lists remediation actions that require approval (if your automation level isn't "Full"). Review the details of each action, the associated evidence, and decide whether to approve or reject it.
History: This tab shows all completed remediation actions, whether they were automatic or manually approved. You can also undo completed actions if necessary (e.g., if a legitimate file was mistakenly quarantined).
Monitor automated investigation progress and results:
When an alert triggers an automated investigation, you can see its progress on the Incident page.
The investigation graph visually represents the entities investigated, verdicts reached (malicious, suspicious, no threats found), and remediation actions taken.
Review the investigation details to understand how the threat was neutralized and what remaining actions (if any) are required.
(3o5) -- MS Defender for Identity (MDI) -- & -- MS Entra ID Protection.
BLUF: Working together to protect identities in hybrid and cloud environments.
Common Tasks. (Using 2 Tools: (1) MS Defender for Identity (MDI), (2) MS Entra ID Protection).
Detecting and Responding to Suspicious Activity with MS Defender for Identity (MDI). -- BLUF: This scenario focuses on setting up MDI to monitor your on-premises Active Directory for signs of compromise and enable security teams to investigate and respond.
Implementing Risky Sign-in and User Policies with Azure AD Identity Protection. -- BLUF: This scenario focuses on configuring Azure AD Identity Protection to automatically respond to risky sign-ins and compromised user accounts in your cloud environment.
Leveraging Unified Incidents and Advanced Hunting in MS Defender XDR. -- BLUF: This scenario focuses on how MDI and Azure AD Identity Protection contribute to a broader security posture within the unified MS Defender XDR (Extended Detection, Investigation & Response) platform, allowing for holistic investigation and proactive threat hunting.
Implementation Steps. (Using 2 Tools)
MS Defender for Identity (MDI): -- BLUF: Leverages on-premises Active Directory signals to identify, detect, and investigate advanced threats and compromised identities.
MS Entra ID Protection: -- BLUF: Focuses on detecting and remediating identity-based risks associated with cloud identities and sign-ins.
Detecting and Responding to Suspicious Activity with MS Defender for Identity (MDI). -- BLUF: This scenario focuses on setting up MDI to monitor your on-premises Active Directory for signs of compromise and enable security teams to investigate and respond. -- Prerequisites: (1) Microsoft 365 E5, Enterprise Mobility + Security E5 (EMS E5), or a standalone Defender for Identity license. (2) Access to the Microsoft Defender Portal (security.microsoft.com) with Security Administrator or Global Administrator roles. (3) Domain Controllers running Windows Server 2012 R2 or newer.
Deploy Microsoft Defender for Identity Sensors:
Sign in to the Microsoft Defender Portal: Go to security.microsoft.com.
Navigate to Settings > Identities > Sensors.
Click Add sensor. This will provide you with a sensor setup package and an access key.
Install the sensor: On each of your domain controllers (and optionally on AD FS/AD CS servers for enhanced visibility), run the downloaded sensor installer with elevated privileges. During the installation, you'll provide the access key obtained from the portal. The sensor silently monitors network traffic and Windows events.
Verify sensor health: After installation, return to Settings > Identities > Sensors in the Defender Portal to ensure your sensors are showing a "Healthy" status and are connected.
Configure Event Collection (if needed):
MDI primarily uses network traffic deep packet inspection. However, for enhanced detection capabilities, it's recommended to configure Windows Event collection from your domain controllers.
You can do this using Group Policy Objects (GPOs) to enable specific audit policies (e.g., Audit Kerberos Authentication Service, Audit Security Group Management, Audit Account Management) on your domain controllers.
For example, to configure audit policies, go to Computer Configuration > Policies > Windows Settings > Security Settings > Advanced Audit Policy Configuration > Audit Policies in a GPO linked to your domain controllers.
Monitor and Investigate Alerts/Incidents:
In the Microsoft Defender Portal, go to Incidents & alerts > Incidents.
MDI alerts will be automatically correlated into incidents, providing a holistic view of an attack across identities, endpoints, and other domains.
When an MDI-generated alert (e.g., "Suspicious service creation," "Potential NTLM relay attack," "Suspicious Kerberos ticket request") appears:
Select the alert/incident to view details, including the affected accounts, devices, and the attack timeline.
Investigate lateral movement paths (LMPs): MDI is excellent at visualizing how an attacker could move laterally. Go to Identities > Lateral movement paths or view them on a user's details page to identify and remediate these potential attack vectors.
Take remediation actions: From the alert/incident page, you can initiate actions like disabling a compromised user account in Active Directory, forcing a password reset, or investigating the associated device using Microsoft Defender for Endpoint.
Implementing Risky Sign-in and User Policies with Azure AD Identity Protection. -- BLUF: This scenario focuses on configuring Azure AD Identity Protection to automatically respond to risky sign-ins and compromised user accounts in your cloud environment. -- Prerequisites: (1) Microsoft Entra ID P2 license (included with Microsoft 365 E5, EMS E5). (2) Access to the Microsoft Entra admin center (entra.microsoft.com) with Security Administrator or Conditional Access Administrator roles.
Configure Risky Sign-in Policy: (7)
Sign in to the Microsoft Entra admin center: Go to entra.microsoft.com.
Navigate to Protection > Identity Protection > Sign-in risk policy.
Assignments:
Users: Select All users (recommended for broad coverage) or specific groups for pilot.
Exclusions: Exclude your emergency access/break-glass accounts to prevent lockout.
Conditions > Sign-in risk: Set the risk level you want to protect against (e.g., Medium and high).
Controls > Access:
Select Grant access.
Choose Require multi-factor authentication.
Enable policy: Set to Report-only initially to monitor impact without enforcing. After review, change to On.
Save the policy.
Configure User Risk Policy: (6)
In the Microsoft Entra admin center, navigate to Protection > Identity Protection > User risk policy.
Assignments: (1) Users: Select All users or specific groups. (2) Exclusions: Exclude emergency access/break-glass accounts.
Conditions > User risk: Set the risk level (e.g., High). This policy acts on the cumulative risk of a user account over time.
Controls > Access:
Select Grant access.
Choose Require password change. This is often the strongest remediation for a compromised user account.
Enable policy: Set to Report-only initially. After review, change to On.
Save the policy.
Implement MFA Registration Policy: (5)
This policy ensures users are prompted to register for MFA if they haven't already, when a risky sign-in occurs or when required by another policy.
In the Microsoft Entra admin center, navigate to Protection > Identity Protection > MFA registration policy.
Assignments: Select All users or specific groups.
Enforce Policy: Set to On.
Save the policy.
~ Note: While this is a standalone policy, it often works in conjunction with the risky sign-in policy. If a risky sign-in occurs and the user isn't MFA registered, the risky sign-in policy can prompt for MFA registration as part of the access control.
Leveraging Unified Incidents and Advanced Hunting in MS Defender XDR. -- BLUF: This scenario focuses on how MDI and Azure AD Identity Protection contribute to a broader security posture within the unified MD Defender XDR (Extended Detection, Investigation & Response) platform, allowing for holistic investigation and proactive threat hunting. -- Prerequisites: (1) MDI and Azure AD Identity Protection deployed and configured (as per previous sections). (2) Other Microsoft Defender XDR components (like Defender for Endpoint, Defender for Office 365, Defender for Cloud Apps) are also deployed and integrated. (3) Security Analyst or Security Reader roles in Microsoft Defender XDR.
Monitor Unified Incidents:
Sign in to the Microsoft Defender Portal: Go to security.microsoft.com.
Navigate to Incidents & alerts > Incidents.
Observe how alerts from MDI (e.g., "Suspicious LDAP reconnaissance") and Azure AD Identity Protection (e.g., "Impossible travel from a user") are automatically correlated with alerts from Defender for Endpoint (e.g., "Malicious file detected") or Defender for Cloud Apps (e.g., "Mass download from unsanctioned app").
Investigate Incidents: Select an incident to view the full attack story, including all affected assets (users, devices, mailboxes, apps) and a correlated timeline of events across the different Defender services. This provides a rich context that isolated alerts would miss.
Use remediation actions: Within the incident, initiate automated or manual response actions that can span across various security domains (e.g., isolating a device, suspending a user account, blocking a malicious IP address).
Proactive Threat Hunting with Advanced Hunting:
In the MS Defender Portal, go to Hunting > Advanced hunting.
Explore Identity-related tables: Familiarize yourself with tables like IdentityInfo, IdentityLogonEvents, IdentityQueryEvents, IdentityDirectoryEvents, and AadSignInEventsV2. These tables contain rich data from MDI and Azure AD Identity Protection.
Write custom queries:
Example 1 (MDI - Lateral Movement Path): Identify accounts with a highly sensitive path to a high-value target that has been observed recently.
Code snippet:
IdentityInfo
| where AccountRiskScore > 0.5 // High risk score
| join kind=inner (
IdentityDirectoryEvents
| where ActionType == "LmpPath"
| where AdditionalFields contains "SensitiveTarget"
) on AccountObjectId
| project AccountDisplayName, AccountUPN, AccountRiskScore, Timestamp, AdditionalFields
| sort by Timestamp desc
Example 2 (Azure AD Identity Protection - Risky Sign-ins): Find sign-ins from Tor exit nodes that were allowed due to Conditional Access policies.
Code snippet:
AadSignInEventsV2
| where RiskDetail == "TorExitNode"
| where ConditionalAccessPolicyApplied == true
| where ResultType == "0" // Sign-in successful
| project Timestamp, AccountDisplayName, IPAddress, RiskDetail, ConditionalAccessPolicyResult
| sort by Timestamp desc
Create custom detection rules: If you discover a specific threat pattern, you can turn your Advanced Hunting query into a custom detection rule to receive automated alerts when that pattern is observed in the future.
Review Identity Secure Score and Security Assessments:
In the MS Defender Portal, go to Identities > Dashboard.
This dashboard provides a consolidated view of your identity security posture, including insights from MDI and Azure AD Identity Protection.
Review the Identity Secure Score to track your progress in improving identity security.
Examine Security assessments (e.g., "Exposed sensitive accounts," "Unsecure domain configurations") to identify vulnerabilities in your on-premises Active Directory detected by MDI, and receive remediation recommendations.
Use the "Active risky users in Microsoft Entra ID" and "High privileged identities" sections to proactively manage and reduce risk.
(4o5) -- MS Defender for O365 (MDO).
BLUF: Focuses on protecting organizations from advanced threats stemming from email, links (URLs), and collaboration tools like MS Teams, SharePoint, and OneDrive.
Common Tasks. (3 Large)
Enabling Safe Attachments to Protect Against (Zero-Day) Malware -- BLUF: This scenario focuses on configuring MDO to automatically detonate and analyze email attachments in a virtual environment to detect and block zero-day malware before it reaches user inboxes.
Implementing Safe Links for (Time-of-Click) URL Protection. -- BLUF: This scenario focuses on configuring MDO to protect users from malicious URLs in emails, Microsoft Teams, and supported Office apps by rewriting and scanning them at the time of click.
Configuring Anti-Phishing Policies (Impersonation Protection). -- BLUF: Focuses on enhancing protection against phishing attacks, especially those involving impersonation (e.g., someone pretending to be your CEO, a trusted vendor, or even your own domain).
Implementation Steps. (3 Large)
Enabling Safe Attachments to Protect Against (Zero-Day) Malware -- BLUF: This scenario focuses on configuring MDO to automatically detonate and analyze email attachments in a virtual environment to detect and block zero-day malware before it reaches user inboxes. -- Prerequisites: (1) MS Defender for O365 Plan 1 or Plan 2 license. (2) Access to the MS Defender Portal (security.microsoft.com) with Security Administrator or Organization Management roles.
Create a Safe Attachments Policy: (6)
Sign in to the Microsoft Defender Portal (security.microsoft.com).
Navigate to Email & collaboration > Policies & rules > Threat policies.
Under the "Policies" section, select Safe Attachments.
On the Safe Attachments page, click Create to start the new policy wizard.
Name your policy: Provide a descriptive name (e.g., "Safe Attachments for All Users") and an optional description. Click Next.
Users, groups, and domains: Define who the policy applies to. For broad protection, select All recipients or choose specific users, groups, or domains for a phased rollout or specific needs. Click Next.
Settings:
Safe Attachments unknown malware response:
Select Block (recommended): This is the most secure option. It prevents the email with the malicious attachment from being delivered.
Alternatively, you can choose 'Dynamic Delivery (Preview messages)' for a better user experience where the email body is delivered first, and the attachment is replaced by a placeholder until it's scanned. If clean, the original attachment is re-inserted; if malicious, the message is quarantined.
Quarantine policy: Choose a quarantine policy that dictates what users can do with quarantined messages and if they receive notifications. The default AdminOnlyAccessPolicy is often used for malware, meaning only admins can release it. You can create a custom quarantine policy to allow user notifications if desired.
Redirect messages with detected attachments: (Optional) If you select Enable redirect, you can specify an email address to send copies of messages with detected malware attachments for further analysis. This is primarily useful for the 'Monitor' action, but can provide insights even with 'Block'.
Click Next. Review: Review your settings. You can click Edit in any section to make changes.
Click Submit to create the policy.
Verify Policy Application and Test:
Allow some time for the policy to propagate (usually a few minutes).
Send a test email with a benign EICAR test file: You can generate a harmless EICAR test file (e.g., paste X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H* into a text file and save it as eicar.com.txt).
Send this file as an attachment to a user covered by the Safe Attachments policy.
Expected outcome: The email should be quarantined, or if Dynamic Delivery was chosen, the attachment should be blocked/replaced.
Check the MS Defender Portal: Go to Email & collaboration > Explorer (or Threat Explorer) to search for the test email. You should see it classified as malware and delivered to quarantine.
Implementing Safe Links for (Time-of-Click) URL Protection. -- BLUF: This scenario focuses on configuring MDO to protect users from malicious URLs in emails, Microsoft Teams, and supported Office apps by rewriting and scanning them at the time of click, -- Prerequisites: (1) MS Defender for Office 365 (MDO) Plan 1 or Plan 2 license.

Apply Safe Links to URLs in supported Office 365 apps. (Recommended, protects links in Word, Excel, PowerPoint, etc.)
Do not track user clicks: (Leave unchecked unless you have a specific reason to not track clicks for reporting/investigation).
Do not allow users to click through to the original URL: (Highly Recommended. If a link is malicious, you generally don't want users bypassing the warning).
Do not rewrite the following URLs in email: (Optional) Add specific, trusted URLs here that you know are safe and don't want rewritten (e.g., internal SharePoint sites, trusted business partners).
Click Next.
Notification: (Optional) Customize the notification text users see when a malicious link is blocked.
Click Next. Review: Review your settings.
Click Submit to create the policy.
Verify Policy Application and Test: (5)
Allow some time for the policy to propagate.
Send a test email with a known malicious URL: You can find safe test URLs (e.g., a "safe" phishing URL that will be flagged by security solutions, not a real malicious one) or simply use a legitimate website URL and observe if it's rewritten.
Send the email to a user covered by the Safe Links policy.
Expected outcome: When the user hovers over the link in the email, they should see that the URL has been rewritten to start with https://safelinks.protection.outlook.com/. If they click a malicious link, they should be redirected to a warning page.
Check the Microsoft Defender Portal: Go to Email & collaboration > Explorer to view URL click events and see if any malicious clicks were blocked.
Configuring Anti-Phishing Policies (Impersonation Protection). -- BLUF: Focuses on enhancing protection against phishing attacks, especially those involving impersonation (e.g., someone pretending to be your CEO, a trusted vendor, or even your own domain). -- Prerequisites: (1) MS Defender for Office 365 (MDO) Plan 1 or Plan 2 license.

Configure Phishing Threshold & Protection: (7)
Phishing threshold: Set the sensitivity. Standard is the default. You can choose Aggressive, More aggressive, or Most aggressive for increased detection, but be mindful of potential false positives.
Spoof intelligence: Keep this enabled (default) to detect when senders are spoofing domains that aren't owned by your organization or are external but attempting to spoof your internal users.
Impersonation: This is key for targeted phishing.
Users to protect: Click Manage (0) user(s) and add the email addresses of key individuals (e.g., CEO, CFO, HR Director) who are frequently impersonated.
Domains to protect:
Include the domains I own: (Recommended) This protects your own organization's domains from being impersonated by external senders.
Include custom domains: (Optional) Add domains of frequently used vendors or partners that might be impersonated.
Add trusted senders and domains: (Use sparingly) These are exceptions where you know a sender is legitimate but might trigger an impersonation alert.
Mailbox intelligence: Enable this to use AI to learn user communication patterns and detect unusual sender-recipient relationships.
Add "First contact safety tip": (Recommended) This shows a warning to users when they receive an email from a sender they don't frequently interact with, helping them identify potential phishing attempts.
Show (?) for unauthenticated senders for SPF/DKIM failures: (Recommended) Adds a question mark to the sender's photo in Outlook for emails that fail authentication.
Show "Via" tag: (Recommended) Adds a "via" tag when the sender's domain doesn't match the original sending domain. Click Next.
Define Actions for Impersonation Detections: (4)
For User impersonation detections and Domain impersonation detections, choose the action:
Redirect message to other email address: Send the suspicious email to a security mailbox for review.
Move message to Junk Email folder: Less impactful, but still flags it.
Quarantine the message (recommended): This moves the email to quarantine and requires admin or user action (depending on quarantine policy).
Deliver the message and add other actions: Deliver to inbox but add a custom header, prepend a subject, or add a safety tip.
Do not apply any action: (Not recommended for most impersonation detections).
For each action, you might also specify a Quarantine policy as in Safe Attachments.
For Spoof intelligence detections, choose an action (e.g., Quarantine the message). -- Click Next.
Review: Review your settings. -- Click Submit to create the policy.
(5o5) -- MS Azure Sentinel (a SIEM & SOAR solution).
BLUF: A Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) solution. Its primary focus is to provide intelligent security analytics and threat intelligence across an enterprise.
Common Tasks. (3 Large)
Connecting Data Sources and Ingesting Security Logs. -- BLUF: Feed your security logs into MS Sentinel to gain visibility and enable detection.
Creating and Customizing Analytics Rules for Threat Detection. -- BLUF: Implement rules to detect suspicious activities and generate alerts/incidents.
Automating Incident Response with Playbooks (SOAR Capabilities). -- BLUF: Use Playbooks in MS Sentinel, powered by Azure Logic Apps, to automate security tasks, enrich incidents, and respond to threats automatically or semi-automatically.
Implementation Steps. (3 Large)
Connecting Data Sources and Ingesting Security Logs. -- BLUF: Feed your security logs into MS Sentinel to gain visibility and enable detection. -- Prerequisites: (1) An Azure subscription. (2) A Log Analytics workspace where Microsoft Sentinel is deployed. (3) Permissions: Microsoft Sentinel Contributor role on the Log Analytics workspace.
Create a Microsoft Sentinel Workspace (if you don't have one):
Sign in to the Azure portal (portal.azure.com).
Search for "Microsoft Sentinel" and select it.
Click Create and select an existing Log Analytics workspace or create a new one. Follow the prompts to complete the workspace creation.
Connect Data Sources:
In the Microsoft Defender Portal (security.microsoft.com), navigate to Microsoft Sentinel > Configurations > Data connectors (or in the Azure portal, navigate to your Sentinel workspace and select Data connectors under "Configuration").
Search for the data connector you want to configure (e.g., "Azure Active Directory," "Microsoft Defender for Endpoint," "Azure Activity," "AWS CloudTrail," "Syslog," "Common Event Format (CEF)").
Select the connector and click Open connector page.
Review prerequisites: Each connector has specific requirements (e.g., enabling specific logs, installing agents, configuring permissions). Ensure these are met.
Follow the configuration instructions:
For Microsoft services (e.g., Azure AD, Microsoft 365, Defender for Endpoint): Often, this is a simple toggle or a few clicks to connect the service directly. For example, for Azure Active Directory, you'll enable specific log types (Sign-in logs, Audit logs) to be sent to Sentinel.
For external services (e.g., AWS CloudTrail, Google Cloud Platform): You'll typically follow instructions to configure API access, deploy a function app, or set up a cloud-to-cloud connection.
For on-premises servers (e.g., Syslog, CEF): You'll need to deploy a Log Analytics agent (or Azure Monitor Agent) on a dedicated Linux or Windows server. This agent collects logs from your devices (e.g., firewalls, routers, Linux servers) and forwards them to your Log Analytics workspace. The connector page will provide detailed setup for the agent and forwarding rules.
Verify data ingestion: After configuring, wait a few minutes. On the connector page, you should see data flowing in the "Data received" graph. You can also go to Logs in your Sentinel workspace and run a simple Kusto Query Language (KQL) query (e.g., SigninLogs | take 10) to see if data is being ingested.
Creating and Customizing Analytics Rules for Threat Detection. -- BLUF: Implement rules to detect suspicious activities and generate alerts/incidents. -- Prerequisites: (1) Data sources connected and ingesting data into Microsoft Sentinel. (2) Permissions: Microsoft Sentinel Contributor role. (3) Familiarity with Kusto Query Language (KQL) for custom rules.
Explore and Enable Built-in Templates: (6)
In the MS Defender Portal, navigate to MS Sentinel > Configuration > Analytics (or in the Azure portal, navigate to your Sentinel workspace and select Analytics).
Go to the Rule templates tab. Microsoft provides hundreds of built-in templates based on common threat scenarios and MITRE ATT&CK tactics.
Filter and review templates: Search for templates relevant to your connected data sources (e.g., filter by "Data sources" or "MITRE ATT&CK tactics").
Create rule from template: Select a template and click Create rule on the details pane.
Customize settings: The wizard will pre-populate details. You can adjust:
General: Name, description, severity, MITRE ATT&CK tactics.
Set rule logic: Review the KQL query, adjust query scheduling (how often it runs) and lookback duration (how far back it looks in logs).
Incident settings: Decide if and how alerts generated by this rule should create incidents (e.g., group alerts into a single incident).
Automated response: (Optional) Link a playbook to run automatically when this rule triggers an alert or incident (covered in the next section).
Click Review and create, then Create. The new rule will appear in the Active rules tab.
Create Custom Analytics Rules from Scratch:
In the Analytics page, click +Create > Scheduled query rule.
General: Provide a unique name, description, severity, and map to relevant MITRE ATT&CK tactics. Set the status to Enabled.
Set rule logic: (7)
Rule query: Write your KQL query to identify suspicious activities. This is where you leverage your ingested data. -- Example (detecting multiple failed sign-ins from a new IP):
Code snippet:
SigninLogs
| where ResultType == "50126" // Failed sign-in
| summarize LoginAttempts = count() by IPAddress, UserPrincipalName
| where LoginAttempts > 5
| join kind=leftanti (
SigninLogs
| where ResultType == "0" // Successful sign-in
| summarize by IPAddress
) on IPAddress // Filter out IPs that have ever had a successful login
| project IPAddress, UserPrincipalName, LoginAttempts
Entity mapping: Map relevant entities (e.g., Account, Host, IPAddress) from your query results. This enriches alerts and helps in investigations.
Query scheduling: Define how often the query runs (e.g., every 5 minutes) and the lookback data (e.g., look back 1 hour).
Alert threshold: Set the number of results that must be returned by the query to trigger an alert (e.g., "Greater than 0").
Incident settings: Configure whether to create incidents from these alerts and how to group them.
Automated response: (Optional) Attach playbooks.
Click Review and create, then Create.
Refine Rules and Reduce False Positives: (5)
Regularly review alerts generated by your rules in Incidents.
For high-volume or false-positive-prone rules, go back to Analytics > Active rules, select the rule, and click Edit.
Adjust query logic: Add where clauses to filter out known benign activities, or use union with other tables for more context.

Automating Incident Response with Playbooks (SOAR Capabilities). -- BLUF: Use Playbooks in MS Sentinel, powered by Azure Logic Apps, to automate security tasks, enrich incidents, and respond to threats automatically or semi-automatically. -- Prerequisites: (1) A Log Analytics workspace with Microsoft Sentinel deployed. (2) Permissions: Logic App Contributor role on the resource group where playbooks are stored, and Microsoft Sentinel Automation Contributor role on the Log Analytics workspace. (3) Familiarity with Azure Logic Apps (basic understanding of triggers and actions).
Deploy or Create a Playbook:
In the MS Defender Portal, navigate to MS Sentinel > Configuration > Automation (or in the Azure portal, navigate to your Sentinel workspace and select Automation).
Go to the Playbook templates tab. You'll find many pre-built templates for common scenarios (e.g., "Block IP," "Get user info," "Send Teams message").
Deploy from template: Select a template and click Create playbook. Follow the wizard to configure connections for the Logic App (e.g., Microsoft Entra ID, Microsoft Defender for Endpoint). This creates an Azure Logic App.
Create a custom playbook: Click Create > Playbook with incident trigger (or alert trigger). This opens the Logic App Designer.
The first step will be the Sentinel Incident/Alert trigger.
Add actions: Add steps to your playbook (e.g., "Get incident entities," "Search Microsoft Defender for Endpoint for device," "Block IP address in firewall," "Send email to SOC team," "Create a ServiceNow ticket"). Configure the parameters for each action.
Save your Logic App.
Grant Permissions for Playbook Execution:
For Microsoft Sentinel to run playbooks, it needs specific permissions on the resource group where your playbooks are located.
In the Automation page in Sentinel, go to the Active playbooks tab.
Click Manage playbook permissions.
In the "Manage permissions" panel, select the resource groups containing your playbooks and click Apply. This grants the Microsoft Sentinel Automation Contributor role to the Sentinel service principal.
Attach Playbooks to Analytics Rules or Automation Rules:
Option A: Attach to an Analytics Rule (for automated response to specific alerts):
Go to Analytics > Active rules.
Select the analytics rule you want to automate, and click Edit.
Go to the Automated response tab.
Under "Alert automation," select your playbook from the dropdown list.
Update the rule. Now, every time this rule generates an alert, the playbook will run.
Option B: Create an Automation Rule (for more flexible incident response or to trigger on incident creation/update):
Go to Automation > Automation rules.
Click +Create > Automation rule.
Trigger: Choose when the rule should run (e.g., "When incident is created," "When incident is updated").
Conditions: Define specific conditions for the incident (e.g., Severity is "High," contains specific entities).
Actions: Select Run playbook and choose your playbook from the list. You can also add other actions like "Change status," "Assign owner," "Add tags."
Set the Rule expiration and Order (if multiple rules apply).
Create the automation rule. This provides a more powerful way to orchestrate responses based on the full incident context, not just individual alerts.
Option C: Manual execution: You can also run playbooks manually from an incident's details page or an entity's page within Sentinel for ad-hoc response.

Detection: Using advanced analytics and machine learning, EDR can identify threats that traditional antivirus software might miss. EDR looks for indicators of compromise (IOCs) - actions linked to potential attacks - and indicators of attack (IOAs) - behaviors associated with known cyber threats.
Response: EDR can be configured to take automated actions to contain a threat, such as isolating an infected device or blocking malicious activity. It can also provide security teams with the information they need to investigate and respond to incidents effectively.
Azure Tool:
Microsoft Defender for Endpoint (with Azure Sentinel): -- BLUF: Azure does not have a standalone EDR tool but uses this tool to provide/run security solutions, facilitates data collection and analysis, and offers tools for automating incident response and threat hunting:
Value & Benefits: (4)
Detection:
MS Defender for Endpoint continuously monitors endpoints (Windows, Linux) in your Azure environment, on-premises, or even in multi-cloud deployments.
It analyzes endpoint behavior using advanced techniques like machine learning to detect anomalies and suspicious activities that might signal a potential attack.
Alerting and Investigation:
When a threat is detected, MS Defender for Endpoint generates alerts in Azure Sentinel (SIEM - Security Information and Event Management) or other security information systems you might have.
Security analysts can then investigate these alerts within Azure Sentinel (SIEM) to understand the scope and potential impact of the incident.
Response:
Azure Sentinel (SEIM) allows for automation and orchestration of security responses.
Perform automation: Based on pre-defined playbooks, you can configure automated actions such as isolating infected devices, blocking malicious URLs, or initiating remediation procedures.
Security analysts can also leverage Azure Sentinel (SIEM) for manual investigation and take necessary actions.
Forensics and Threat Hunting:
MS Defender for Endpoint stores endpoint data for up to six months. This allows security analysts to go back in time and investigate the root cause of an incident.
Azure Sentinel (SIEM) can further enrich this data with information from other security sources, providing a broader context for threat-hunting activities.
SASE (Secure Access Service Edge).
BLUF (2): (1) It's a cloud-based security model that combines networking and security functions into a single service. (2) A single security checkpoint, offering secure access and protection for users, devices, and applications regardless of their location.
Concept:
Traditionally, network security was managed through on-premise solutions and a "castle and moat" approach, where a central location protected the entire network.
SASE moves these functionalities to the cloud edge, providing distributed security closer to users and apps.
