After containing a security incident, the incident response team conducts a root cause analysis. Which of the following is the PRIMARY purpose of this activity?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To identify the initial attack vector
Root cause analysis aims to identify the underlying cause of the incident to prevent recurrence. It is a key part of post-incident activity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
To identify the initial attack vector
Why this is correct
Identifying the initial attack vector is the primary objective of root cause analysis because it pinpoints the exact vulnerability or entry point exploited by the threat actor. This technical understanding allows security teams to implement targeted remediation controls, such as patching specific software or updating firewall rules, to prevent identical future compromises.
- ✗
To calculate the financial loss
Why it's wrong here
Although quantifying the financial impact of a breach is important for business leadership and insurance claims, it is a business impact analysis function rather than a technical root cause analysis. Root cause analysis focuses strictly on the technical "how" and "why" of the exploit, rather than the monetary damages incurred during or after the event.
- ✗
To document the timeline
Why it's wrong here
Establishing a chronological timeline of attacker activities is a critical component of the broader incident reconstruction phase, but it serves as an input to root cause analysis rather than the ultimate goal. The timeline details when events occurred, whereas root cause analysis seeks to explain the underlying systemic vulnerabilities that permitted those events to happen in the first place.
- ✗
To assign blame to individuals
Why it's wrong here
Effective incident response relies on a blameless culture to ensure transparent reporting and honest post-incident reviews. Assigning personal fault to employees or administrators counterproductively discourages transparency and fails to address the systemic process failures, misconfigurations, or software bugs that actually enabled the security incident.
