Eccouncil Exam 212-89 Topic 5 Question 81 Discussion

In the incident handling and response (IH&R) process, backing up the data on affected systems is a critical step that usually falls under the Containment phase. The Containment phase is crucial for limiting the scope and severity of an incident, ensuring that it does not spread further or affect additional systems. Backing up affected systems during containment is essential for several reasons: it preserves a snapshot of the system in its current state for forensic analysis, ensures that data is not lost if the system needs to be wiped or altered during the response process, and helps in the recovery process if data is corrupted or lost.

By performing a complete backup of the infected system during the Containment phase, Alice ensures that there is a reliable copy of all data and system states before any major actions, such as eradication or deeper forensic analysis, are taken. This step is also preparatory for the potential use of the backup in analyzing how the incident occurred and in restoring system functionality after the incident is resolved.
