Final answer:
The preservation of evidence is performed during the Containment, Eradication, and Recovery phase of incident response, ensuring evidence is kept intact for future inquiries.
Step-by-step explanation:
The preservation of evidence in incident response is performed during the Containment, Eradication, and Recovery phase. Preservation is crucial at this phase to ensure that any evidence of the incident is secured for future analysis, legal purposes, or post-incident review. After an incident is detected and analyzed, which happens in the Detection and Analysis phase, the next immediate step is to contain the incident to prevent further damage, eradicate the source of the incident, and then recover any affected systems.
During containment, it is vital to preserve evidence in its original state, which involves careful documentation and handling of the affected systems and data involved. Proper preservation methods allow organizations to perform a thorough investigation during the Post-Incident Activity phase and develop lessons learned to improve future preparedness.
