What is the goal of the testing mandated by IR.L2-3.6.3?

The goal of the testing mandated by IR.L2-3.6.3 is to assess the effectiveness of incident response capabilities. This is crucial because an organization must ensure that its incident response processes are not only well-documented but also function as intended during actual incidents. Testing incident response capabilities allows organizations to identify weaknesses, validate procedures, and ensure that team members are prepared and able to respond effectively when incidents occur. This process helps improve the organization's overall cybersecurity posture by preparing it to handle potential threats more efficiently.

The other options do not align with the specific intent of IR.L2-3.6.3. Improving budget allocation for IT focuses on financial management rather than incident response efficacy. Conducting background checks on staff pertains to personnel security and does not address incident management processes. Similarly, manually reviewing each incident may be part of a larger review process but does not specifically evaluate the overall effectiveness of the incident response capabilities as mandated by this requirement.
