What are the phases of the incident response lifecycle?

The key stages in the lifecycle of an incident response plan typically include:

1. Preparation: This stage involves developing and documenting the incident response plan, establishing roles and responsibilities, conducting training and awareness programs, and ensuring that the necessary tools and resources are in place.

2. Detection and Identification: In this stage, incidents are detected through various security controls and monitoring mechanisms. The goal is to identify the nature and scope of the incident to determine the appropriate response.

3. Containment: Once an incident is identified, the next step is to contain it to prevent further damage or impact. This may involve isolating affected systems, blocking malicious activities, and implementing temporary solutions.

4. Eradication: After containing the incident, the focus shifts to eradicating the root cause to ensure that the issue is fully resolved. This may involve removing malware, applying security patches, and implementing long-term solutions to prevent future incidents.

5. Recovery: The recovery stage involves restoring affected systems and services to normal operation. This includes data restoration, system reconfiguration, and ensuring that all necessary measures are taken to resume business operations.

6. Lessons Learned: After the incident has been resolved, it is important to conduct a post-incident review to analyze what happened, identify areas for improvement, and update the incident response plan accordingly. This stage helps organizations learn from past incidents and enhance their overall security posture.

Each of these stages plays a critical role in managing threats effectively by providing a structured approach to detecting, responding to,
