What are the four phases of the Incident Response Lifecycle?

The correct answer highlights the comprehensive structure of the Incident Response Lifecycle, which is a critical framework for effectively managing cybersecurity incidents.

The lifecycle consists of several phases, starting with Preparation, which involves establishing and training response teams, creating response plans, and implementing necessary tools. This is followed by the Detection and Analysis phase, where potential security incidents are identified and assessed to determine their nature and impact. Next is the Containment, Eradication, and Recovery phase, which focuses on containing the incident to prevent further damage, eradicating the threat, and restoring systems to normal operations. Finally, the Post-Incident Activity phase involves reviewing and analyzing the response to improve future incident responses and strengthen overall security posture.

This systematic approach ensures that organizations are prepared for incidents, can respond quickly and effectively, and learn from each event to bolster their defenses against future threats. The other choices do not encapsulate all the necessary phases involved in a thorough incident response process.
