Which phase of the incident response process involves detecting and analyzing security incidents?

The phase of the incident response process that focuses on detecting and analyzing security incidents is the Detection and Analysis phase. This is a crucial step in the incident response lifecycle because it is during this phase that security teams actively monitor systems and networks to identify potential security threats.

In this phase, various tools and techniques, such as intrusion detection systems, log analysis, and threat intelligence, are employed to recognize indicators of compromise or abnormal behaviors that may signify an ongoing security incident. Once a potential incident is detected, the analysis involves a deeper investigation to understand the scope, impact, and nature of the incident, allowing responders to make informed decisions on how to address it. This analytical process is what enables the team to differentiate between false positives and actual incidents, ensuring that effective containment and remediation measures can be put in place.

The other phases play important roles in the overall incident response framework, but they focus on different aspects. Preparation involves establishing the policies, procedures, and tools needed to effectively respond to incidents. Containment, Eradication, and Recovery deal with addressing an incident once it has been confirmed, and Post-Incident Activity involves reviewing and refining the incident response process after the incident has been resolved.
