Incident Eradication and Recovery
After incident containment, the eradication phase focuses on eliminating all components and artifacts related to the security incident. This may involve cleaning or replacing affected systems, applying patches, updating software, and removing unauthorized access accounts. Appropriate documentation should be maintained during the eradication phase to track all actions taken by the Incident Response Team. Once the threat has been eradicated, the recovery phase starts. The primary goal of the recovery phase is to restore affected systems, applications, and data to normal operation with minimal impact on the organization's business continuity. This may involve deploying backups, performing system reconfiguration, and validating the completeness and integrity of restored data. The recovery phase should also include monitoring efforts to ensure that the threat has been completely eliminated and to detect potential resurgence.
