ISC2 CISSP Practice Question

A breach attack simulation is the most appropriate choice because it provides a controlled, realistic simulation of sophisticated threat actor techniques without the risks associated with an actual penetration test on critical financial systems. The simulation can be customized to mimic the specific tactics, techniques, and procedures (TTPs) of Advanced Persistent Threats (APTs) targeting the financial sector, while evaluating the detection and response capabilities of the security team. Unlike vulnerability assessments which focus on identifying vulnerabilities without exploitation, or table-top exercises which are discussion-based, breach attack simulations involve executing actual attack techniques in a controlled manner to test real-world defensive capabilities and response procedures. Purple team exercises, while valuable, typically involve broader collaboration between offensive and defensive teams rather than specifically simulating sophisticated threat actor TTPs against targeted systems.
