Section 1: Fundamentals of Risk Management

Risk management is a systematic process to identify, analyze, evaluate, treat, monitor, and review risks, as defined in ISO 31000 and adapted for cybersecurity. Risk is the effect of uncertainty on objectives, often expressed as likelihood times impact. In cybersecurity, it encompasses threats like malware, phishing, or insider attacks.

Core Concepts:

• Threat: A potential cause of an unwanted incident (e.g., hacker exploiting a vulnerability).
• Vulnerability: A weakness in a system (e.g., unpatched software).
• Impact: Consequences, such as financial loss or data breach.
• Likelihood: Probability of occurrence.

Hands-On Lab: Students use tools like Nmap to scan for vulnerabilities in a virtual network, then calculate basic risk scores.
