What are the primary steps involved in the Incident Response Process (IRP)?

The correct choice outlines a structured approach to incident response by emphasizing critical phases that ensure comprehensive management of security incidents. The steps mentioned—Contain, Eradicate, Recovery, and PIA (Post-Incident Analysis)—are fundamental as they provide a clear action plan to address security breaches effectively.

During the Contain phase, the primary goal is to limit the damage caused by an incident and prevent further deterioration of systems. Once containment is achieved, the Eradicate phase follows, which involves identifying the root cause of the incident and removing any malicious elements from the environment. Recovery is thereafter focused on restoring affected systems to normal operations, ensuring that vulnerabilities are patched in the process.

Post-Incident Analysis is crucial for learning from incidents; it involves reviewing what occurred, understanding the effectiveness of the response, and determining how similar incidents can be prevented in the future. This phase not only helps in improving the incident response plan but also in reinforcing the security posture of the organization.

In contrast, the other options do not encapsulate the structured methodology required for a robust incident response. For example, while detecting and reviewing incidents are indeed important (as seen in option A), they do not comprehensively outline the steps required to mitigate and learn from incidents as effectively as the chosen
