Threat analysis is defined as:

• A. The examination of threat sources against system vulnerabilities to determine the threats for a particular system in a particular operational environment.
• B. The formal description and evaluation of threats.
• C. A risk management plan.
• D. A routine vulnerability scan.

Answer: (A)

Threat analysis is about identifying plausible threats by looking at who or what could cause harm (threat sources) and how the system’s weaknesses (vulnerabilities) could be exploited, all within the actual operating environment. This approach determines which threats are relevant to the specific system, considering the context, assets at risk, and potential attacker capabilities or other threat sources. It’s more than just listing threats; it links them to weaknesses and the real-world environment to show what could realistically materialize and therefore what should be addressed.

This differs from simply describing and evaluating threats in a vacuum, which may ignore how vulnerabilities and environment shape actual risk. It also isn’t a risk management plan, which outlines how to handle risks overall, nor a routine vulnerability scan, which identifies weaknesses without tying them to threat sources or an operating context.
