Cyber Security I

Cybersecurity I: Systems & Defense

Class Overview

In an increasingly connected world, protecting information is more critical than ever. This course introduces you to the high-stakes field of Cybersecurity, covering the fundamental principles of protecting networks, systems, and data from digital attacks. You will explore the mindset of both attackers and defenders, learning how to identify vulnerabilities and implement robust security measures. Through interactive labs and simulated environments, you will gain the practical skills needed to navigate the evolving landscape of digital threats.

Key Topics

• The CIA Triad: Master the core pillars of security—Confidentiality, Integrity, and Availability—and how they apply to every digital system.

• Network Security: Understand how data travels across the internet and how to secure routers, switches, and wireless connections.

• Threats, Attacks, and Vulnerabilities: Identify common malware (viruses, ransomware) and social engineering tactics like phishing.

• Cryptography: Learn the basics of encryption and decryption to keep sensitive information private and secure.

• Defensive Tactics: Practice implementing firewalls, multi-factor authentication (MFA), and secure password policies to harden a system's defenses.

Primary Objectives

By the end of this course, you will be able to:

• Identify and categorize various types of cyber threats and digital vulnerabilities.

• Configure basic security settings on devices and networks to mitigate risks.

• Explain the role of encryption in protecting data at rest and in transit.

• Evaluate the ethical and legal implications of cybersecurity in a modern society.
