When discussing a remediation plan for acritical vulnerability, it is essential to include arollback planbecause:

Post-Implementation Issues:Changes can cause unexpected issues or system instability.

Risk Mitigation:A rollback plan ensures quick restoration to the previous state if problems arise.

Best Practice:Always plan for potential failures when applying significant security changes.

Change Management:Ensures continuity by maintaining a safe fallback option.

Other options analysis:

A. Canceling remediation:This is not a proactive or practical approach.

C. Severity-based rollback:Rollback plans should be standard regardless of severity.

D. Additional staff presence:Does not eliminate the need for a rollback strategy.
