Go through each question and its explanation. Use this set as a focused practice pack for Incident Response.
Short-term containment provides immediate isolation—such as disconnecting a system from the network—to stop ongoing damage. Long-term containment maintains stability while enabling deeper investigation, often using patches or temporary network segmentation until systems are rebuilt.
For complete preparation, combine this set with full subject-wise practice for Incident Response. You can also explore other subjects and sets from the links below.
Before reintroducing a system to production, teams must re-image or verify its integrity and run validation scans. This ensures that no residual malware or hidden backdoors remain active.
Lessons learned from containment and recovery are vital for continuous improvement. Teams analyze what worked, what failed, and update playbooks, response timelines, and communication flows accordingly. Regular post-mortems turn incidents into training opportunities for stronger resilience.
Confidential communication ensures sensitive details don’t leak externally. Updates should be limited to IR and management personnel, keeping consistent, verified information flow to avoid confusion or panic.
Containment aims to control and minimize the damage of an ongoing incident. It focuses on isolating affected systems or networks so that the threat does not spread further, buying time for eradication and recovery planning.
Short-term containment focuses on halting the spread of an incident immediately. Disconnecting an infected system prevents lateral movement of malware and buys time for forensic analysis and eradication planning.
Forensic evidence helps investigators trace the origin and scope of an attack. Preserving logs, memory dumps, and network captures ensures that later analysis and legal teams have valid, untampered data to work with.
Eradication focuses on eliminating the root cause of the incident—malware, backdoors, or misconfigurations—so that the threat cannot reappear. After eradication, verification scans and audits confirm that systems are clean.
Recovery is the process of restoring systems to normal operations in a controlled and verified manner. It includes validating system integrity, patching vulnerabilities, and continuous monitoring for re-infection.
Containment typically includes: 1. Identifying affected assets. 2. Disconnecting or isolating compromised systems. 3. Blocking malicious IPs or domains. 4. Applying temporary patches or access restrictions. 5. Preserving evidence for investigation. Each step minimizes spread while maintaining data integrity for future analysis.
Recovery focuses on restoring affected systems safely. Key steps include re-imaging or cleaning compromised hosts, restoring data from verified backups, reconfiguring network access, verifying system integrity, and gradually reconnecting systems to production with heightened monitoring. After recovery, post-incident reviews confirm success.
Containment must act fast to reduce damage but should not destroy critical evidence or interrupt essential services. Acting too aggressively may shut down business systems, while slow responses allow threats to spread. The best IR teams use context-driven judgment for each case.
System validation ensures that the root cause is fully eliminated and normal operations are safe to resume. It involves vulnerability scans, configuration checks, and integrity validation to confirm no leftover malware, unauthorized users, or open attack paths exist.
