Incident Response Policy

Correct Answer: Post-Incident Activity

Post-Incident Activity is the correct phase of the Incident Response Policy represented in this scenario. After implementing new security controls and observing a significant decrease in incidents, the organization is engaging in a review and analysis of the effectiveness of these controls. This evaluation of the impact of security measures and the resulting reduction in incidents is a key component of Post-Incident Activity. It involves assessing the effectiveness of the incident handling process, identifying areas for improvement, and implementing lessons learned to enhance overall security posture. This phase is crucial for continuous improvement in an organization's security strategy and incident response capabilities.

Correct Answer: Lack of a well-defined Incident Response Policy

The correct answer is 'Lack of a well-defined Incident Response Policy' because an effective Incident Response Policy clearly specifies the necessary steps during a security incident, easing the decision-making process. The other options may contribute to the problem, but the main issue lies in the absence of a proper policy.

Correct Answer: Contain with strict communication controls

The correct answer is 'Contain with strict communication controls' because containing the incident involves limiting the impact and preventing further damage. Imposing strict communication controls will prevent leaked data from spreading. The other options are either not relevant or are part of later stages.
