Slide 4 - The Incident Response Logic
| Phase | Medical Analogy | Cybersecurity Action |
|---|---|---|
| Containment | Prevent metastasis (stop spread) | Isolate hosts & block malicious traffic |
| Resection/Fix | Surgical removal of damaged tissue | Remove compromised accounts & services |
| Chemotherapy | Eliminate invisible residual cells | Patch, reimage & verify removal |

Slide 6 - Dual Containment Strategy
Short-Term Containment Goal: Stop the bleeding.
- Isolate infected hosts entirely.
- Block malicious IP addresses.
- Terminate suspicious outbound traffic to C2 servers.
- Disable compromised user accounts.
- Shut down specific services.
Long-Term Containment Goal: Maintain operations safely.
- Build a controlled environment.
- Deploy patches to vulnerable systems.
- Harden access controls.
- Preserve forensic evidence for later eradication analysis.

Eradication Process
Removing every trace and confirming a clean slate
Slide 8 of 11
Slide 8 - Key Questions for Eradication
- What was left behind? (Backdoors, registry keys)
- Who was touched? (Systems, accounts, compromised assets)
- When did it start? (Determining the full attack timeline and dwell time)
- How to proceed? (Patch at the root, reimage machines, verify clean status)

Lessons Learned
Learning from past failures and success stories
Slide 10 of 11
Slide 10 - Historical Security Case Studies
Target (2013): Failure to Contain
- Attackers entered via third-party HVAC vendor.
- Security tool flagged malware.
- Alerts were ignored.
- Result: 40 million credit cards stolen.
- Failure: Containment never occurred despite detection.
Maersk (2017): Lucky Recovery
- NotPetya ransomware attack.
- 45,000 PCs and 4,000 servers destroyed.
- Total Active Directory infrastructure lost.
- Recovery was accidental (offline server in Ghana survived).
- Takeaway: Lack of proper plan is not a strategy.

Slide 11 - Conclusion
Plan, Contain, Eradicate, Verify.
Containment is about buying time; Eradication is about restoring integrity. Always confirm clean.
