Question 1:
Which of the following test makes sure the modified or new system includes appropriate access controls and does not introduce any security holes that might compromise other systems?
A.Recovery testing
B.Security testing
C.Stress/volume testing
D.Interface testing
Answer: B
Explanation:
B. Security testing
Security testing is explicitly designed to evaluate a system to discover vulnerabilities, ensure that technical and administrative access controls work as intended, and verify that the system does not introduce new security risks or loopholes that could compromise the surrounding environment.
Incorrect:
A. Recovery testing
Recovery testing evaluates a system's ability to recover from hardware failures, software crashes, or catastrophic data loss. It focuses on backup restoration, disaster recovery timelines, and data integrity rather than access controls or security holes.
C. Stress/volume testing
This is a form of performance testing designed to analyze how a system behaves under extreme workloads, peak user volumes, or resource constraints. It evaluates stability and availability, not security controls.
D. Interface testing
Interface testing verifies that different components, modules, or systems communicate and pass data between each other correctly and without errors. While it ensures proper interoperability, it does not broadly evaluate overall system access controls or holistic security vulnerabilities.
Question 2:
Which of the following phases of a software development life cycle normally addresses Due Care and Due Diligence?
A.Implementation
B.System feasibility
C.Product design
D.Software plans and requirements
Answer: D
Explanation:
D. Software plans and requirements
This is the initial phase where an organization identifies the “Rules of Engagement” for the project, including legal requirements (GDPR, HIPAA, etc.) and business risks.
By investigating which laws apply and what security standards are necessary, the organization is actively performing Due Diligence.
By documenting these requirements as mandatory project goals, the organization is setting the standard for Due Care, ensuring that a “prudent person” would find the resulting product sufficiently protected.
Incorrect:
A. Implementation
This phase involves the actual writing of code, configuration of systems, and physical deployment of the software.
While this stage demonstrates Due Care through the act of building security controls, it is a reactive phase based on earlier decisions. It does not “address” the foundational research and investigation required to establish what the organization’s legal and ethical obligations are in the first place.
B. System feasibility
The feasibility phase is primarily concerned with determining if a project is viable from a financial, technical, and operational standpoint.
Although it involves some level of investigation, it lacks the comprehensive scope of security due diligence, which must account for regulatory compliance, data protection laws, and overarching risk management frameworks.
C. Product design
In the design phase, technical specifications are created, such as choosing encryption algorithms or architecting the network layout.
While the design reflects the requirements, the legal mandate to act (Due Diligence) and the standard to which the organization will be held (Due Care) are defined prior to technical drafting. Design is an engineering response to the requirements set in the previous phase.
Question 3:
Which of the following is less likely to be included in the change control sub‑phase of the maintenance phase of a software product?
A.Estimating the cost of the changes requested
B.Recreating and analyzing the problem
C.Determining the interface that is presented to the user
D.Establishing the priorities of requests
Answer: D
Explanation:
D. Establishing the priorities of requests
While change control involves evaluating, approving, and documenting changes, the prioritization of requests is typically handled at a higher management or planning level, not within the technical change control sub‑phase itself.
Change control focuses on impact analysis, cost estimation, risk assessment, and approval workflows, not prioritization.
Therefore, this activity is less likely to be formally included in the change control sub‑phase.
Incorrect
A. Estimating the cost of the changes requested
Cost estimation is a key part of change control.
It helps decision‑makers understand the financial impact of implementing or rejecting a change.
B. Recreating and analyzing the problem
Analyzing the problem is essential to determine whether a change is necessary and to assess its scope.
This ensures that the change request is valid and addresses the root cause.
C. Determining the interface that is presented to the user
User interface considerations may be part of the change request evaluation.
Change control includes assessing how modifications affect usability and user experience.
Question 4:
Which of the following statements pertaining to key management is incorrect?
A.The more a key is used, the shorter its lifetime should be.
B.When not using the full keyspace, the key should be extremely random.
C.Keys should be backed up or escrowed in case of emergencies.
D.A key's lifetime should correspond with the sensitivity of the data it is protecting.
Answer: B
Explanation:
B. When not using the full keyspace, the key should be extremely random.
This statement is incorrect. In cryptographic principles, a key should always be generated with maximum entropy (extremely random), regardless of whether you are utilizing the full keyspace or a restricted subset. Cryptographic strength depends heavily on high randomness to resist brute-force or dictionary attacks under any constraint.
Correct Statements (Incorrect Answers to the Question)
A. The more a key is used, the shorter its lifetime should be.
This statement is correct. High frequency of key use increases the volume of ciphertext generated under that single key. This gives attackers more material to perform cryptanalysis (such as statistical or differential attacks), meaning heavily used keys must be rotated and retired faster.
C. Keys should be backed up or escrowed in case of emergencies.
This statement is correct. For data-at-rest encryption keys (such as storage or file encryption), keys must be backed up securely or placed in a managed escrow. If the primary key is lost or corrupted without a backup, the underlying data is permanently unrecoverable.
D. A key's lifetime should correspond with the sensitivity of the data it is protecting.
This statement is correct. Highly sensitive or classified data requires stricter protection, meaning the keys encrypting it should have a shorter cryptoperiod (lifetime) to limit exposure window and mitigate risk if a compromise occurs.
Question 5:
Which of the following statements pertaining to link encryption is false?
A.It encrypts all the data along a specific communication path.
B.It provides protection against packet sniffers and eavesdroppers.
C.Information stays encrypted from one end of its journey to the other.
D.User information, header, trailers, addresses and routing data that are part of the packets are encrypted.
Answer: C
Explanation:
C. Information stays encrypted from one end of its journey to the other.
This statement is false. Link encryption encrypts data only between two adjacent network nodes (hop-by-hop). When the data reaches an intermediate node (like a router or switch), it must be decrypted so the device can read the routing headers to forward it to the next hop. End-to-end encryption is the mechanism where data stays encrypted from the source all the way to the final destination.
True Statements (Incorrect Answers to the Question)
A. It encrypts all the data along a specific communication path.
This statement is true. Link encryption is applied at the physical or data link layer, meaning it encrypts all data traversing that specific physical communication link between two nodes.
B. It provides protection against packet sniffers and eavesdroppers.
This statement is true. Because everything traveling over the physical wire or wireless link is completely encrypted, anyone tapping into or sniffing that specific link will only see ciphertext.
D. User information, header, trailers, addresses and routing data that are part of the packets are encrypted.
This statement is true. Unlike end-to-end encryption (which only encrypts the payload), link encryption encrypts the entire packet—including the routing headers, trailers, and addressing details—making it impossible for an eavesdropper on that link to determine the packet's ultimate destination or origin.

Question 6:
Which of the following does NOT concern itself with key management?
A.Internet Security Association Key Management Protocol (ISAKMP)
B.Diffie-Hellman (DH)
C.Cryptology (CRYPTO)
D.Key Exchange Algorithm (KEA)
Answer: C
Explanation:
✅ Cryptology
Cryptology is the science that encompasses both cryptography and cryptanalysis. It focuses on the mathematical principles—such as number theory, formulas, and algorithms—that form the foundation of encryption and decryption techniques.
Cryptology itself is not directly concerned with key management, making it the correct answer.
❌ Internet Security Association and Key Management Protocol (ISAKMP)
ISAKMP is a key management protocol used with IPsec.
It is defined in RFC 2408 and provides a framework for:
Establishing Security Associations (SAs)
Authentication
Key exchange negotiation
ISAKMP does not perform the actual key exchange. Instead, it provides the framework within which key exchange protocols operate.
❌ Oakley Key Determination Protocol
Oakley is a key agreement protocol responsible for performing the actual key exchange.
It enables authenticated parties to securely exchange keying material over an insecure network.
Oakley uses the Diffie-Hellman key exchange algorithm to establish shared secret keys.
❌ Diffie-Hellman Key Exchange
Diffie-Hellman (D-H) is one of the earliest and most widely used key exchange protocols.
It allows two parties with no prior shared secret to securely establish a shared secret key over an insecure communication channel.
The established shared key can then be used with a symmetric encryption algorithm to protect subsequent communications.
Question 7:
Which of the following statements pertaining to message digests is incorrect?
A.The message digest should be calculated using at least 128 bytes of the file.
B.Two different files should not have the same message digest.
C.The original file cannot be created from the message digest.
D.Messages digests are usually of fixed size.
Answer: A
Explanation:
C. The original file cannot be created from the message digest.
Correct Statement
This describes the one-way property (pre-image resistance) of a hash function. A message digest is a “fingerprint” of the data. Because it is a mathematical “one-way” process, you cannot reverse-engineer or “decompress” the digest to get the original data back.
B. Two different files should not have the same message digest.
Correct Statement
This refers to Collision Resistance. While mathematically possible (since there are infinite possible files and finite possible hashes), a strong cryptographic hash algorithm makes it computationally infeasible for two different inputs to produce the same output.
A. The message digest should be calculated using at least 128 bytes of the file.
INCORRECT Statement (The Answer)
A message digest is calculated using the entirety of the file or message, regardless of its size. If you only hash a portion of the file (like the first 128 bytes), any changes made to the rest of the file would go undetected, defeating the purpose of integrity checking.
D. Messages digests are usually of fixed size
Correct Statement
Regardless of whether the input file is 1 KB or 1 TB, the resulting message digest will always be a specific, fixed length determined by the algorithm used. For example, SHA-256 always produces a 256-bit (32-byte) digest.
Question 8:
Sensitivity labels are an example of what application control type?
A.Preventive security controls
B.Detective security controls
C.Compensating administrative controls
D.Preventive accuracy controls
Answer: A
Explanation:
✅ Sensitivity labels
Sensitivity labels are a preventive security application control. They help protect data by classifying and labeling information so that appropriate protection policies—such as encryption, access restrictions, and usage controls—can be automatically enforced.
Examples of preventive security controls include: Sensitivity labels, Firewalls , Reference monitors, Traffic padding, Encryption, Data classification, One-time passwords (OTPs), Contingency planning and Separation of development, testing, and production environments
❌ Detective security controls
Detective controls are designed to identify and report security incidents after they occur, rather than prevent them.
Examples include: Intrusion Detection Systems (IDS), Security monitoring, Audit trails and Log analysis
❌ Compensating administrative controls
Incorrect. There is no recognized category known as compensating administrative application controls in this context.
Compensating controls are alternative safeguards implemented when a primary control cannot be used, but they are not classified as an application control type here.
❌ Preventive accuracy controls
Incorrect. Accuracy controls are designed to ensure that data entered into a system is complete, valid, and accurate.
Examples include: Data validation checks , Input forms, Custom input screens, Validity checks, Contingency planning and Backups
These controls focus on data integrity, not on applying security classifications such as sensitivity labels.
Question 9:
How should a doorway of a manned facility with automatic locks be configured?
A.It should be configured to be fail-secure.
B.It should be configured to be fail-safe.
C.It should have a door delay cipher lock.
D.It should not allow piggybacking.
Answer: B
Explanation:
✅B. It should be configured to be fail-safe.
In physical security and life safety regulations, any doorway of a manned facility must prioritize human life above property protection. A "fail-safe" configuration ensures that if power fails or an emergency occurs, the automatic locks automatically unlock, allowing occupants to evacuate safely without getting trapped inside.
❌ A. It should be configured to be fail-secure.
A "fail-secure" configuration keeps the door locked when power fails to protect assets and prevent unauthorized entry. While appropriate for unmanned sensitive storage areas (like an offsite data vault), using it on a manned facility poses a severe life safety hazard because it can trap people inside during emergencies.
❌ C. It should have a door delay cipher lock.
A door delay cipher lock is a specific type of electronic lock mechanism that requires a code and can introduce an intentional delay before opening. It is a control choice for restricting access, but it does not address the fundamental structural safety and failure-mode requirements for a manned facility's exit paths.
❌D. It should not allow piggybacking.
While preventing piggybacking (an unauthorized person following an authorized person through a door) is an important security goal, it describes a policy or a secondary control (like turnstiles or mantraps). It does not answer how the automatic locking mechanism itself should be inherently configured to operate for the safety of a manned building.
Question 10:
Which of the following statements pertaining to RADIUS is incorrect:
A.A RADIUS server can act as a proxy server, forwarding client requests to other authentication domains.
B.Most of RADIUS clients have a capability to query secondary RADIUS servers for redundancy.
C.Most RADIUS servers have built-in database connectivity for billing and reporting purposes.
D.Most RADIUS servers can work with DIAMETER servers.
Answer: D
Explanation:
✅ D. Most RADIUS servers can work with DIAMETER servers.
This statement is incorrect. While DIAMETER was developed as the modern successor to RADIUS and includes a level of backward compatibility to interoperate with legacy RADIUS systems, the opposite is not true. Standard legacy RADIUS servers do not inherently possess the software framework, protocol mechanics, or architectural capacity to communicate directly with or process messages from DIAMETER servers without specialized translation gateways or proxy wrappers.
❌ A. A RADIUS server can act as a proxy server, forwarding client requests to other authentication domains.
This statement is correct. RADIUS architecture natively supports proxying, allowing a local RADIUS server to receive an authentication request from a user outside its scope and securely forward it to a remote RADIUS server belonging to another organization or domain for validation.
❌ B. Most of RADIUS clients have a capability to query secondary RADIUS servers for redundancy.
This statement is correct. To ensure high availability and prevent a single point of failure, typical RADIUS clients (such as network switches, VPN gateways, or wireless access points) allow administrators to configure a primary and one or more secondary/backup RADIUS servers for failover.
❌ C. Most RADIUS servers have built-in database connectivity for billing and reporting purposes.
This statement is correct. Since Accounting is a core pillar of AAA (Authentication, Authorization, and Accounting) services, standard RADIUS server software natively includes plug-ins or features to log session durations and data usage parameters directly into SQL databases, LDAP directories, or flat logs for billing and tracking purposes.
