Which TWO actions are key components of the 'Containment' phase in incident response?
⚠ Common exam trap
Test-takers frequently confuse the order of incident response phases: candidates often mistake eradication (Option C) or recovery (Option A) for containment, but containment must occur first to stop the attack from spreading before any cleanup or restoration begins.

Correct answer & explanation
✓
Implementing temporary workarounds to stop damage
Containment is the immediate priority in incident response to stop the spread of damage and prevent further compromise. Implementing temporary workarounds—such as isolating affected systems, blocking malicious IPs via firewall rules, or disabling compromised accounts—directly halts the incident's impact without waiting for full eradication or recovery. Option E is also correct because deploying patches or configuration changes can serve as a containment measure by closing the vulnerability that allowed the attack, thereby preventing the attacker from re-entering or continuing the exploit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restoring systems from backups
Why it's wrong here
Restoration is part of recovery, not containment.
- ✓
Implementing temporary workarounds to stop damage
Why this is correct
Short-term containment prevents further harm.
- ✗
Eradicating malware from infected systems
Why it's wrong here
Eradication follows containment.
- ✗
Writing a final incident report
Why it's wrong here
Reporting is part of post-incident activity.
- ✓
Deploying patches or configuration changes to secure systems
Why this is correct
Long-term containment hardens systems against further exploitation.
