Performing computer or network Forensics is an activity recommended by the _________ function within the NIST CSF.

Question

BlackTom AI · Accepted Answer

The Respond function in the NIST Cybersecurity Framework (CSF) encompasses activities such as response planning, communications, analysis, mitigation, and improvements—so performing computer or network forensics falls squarely under Respond.

1) Relevant knowledge points and concepts
- NIST CSF has five core functions: Identify, Protect, Detect, Respond, Recover.
- Respond includes the Analysis category, which covers investigation and forensic activities to determine scope, impact, and root cause of incidents.
- Forensics involves evidence collection, preservation, analysis, and reporting to support containment, mitigation, and potential legal actions.

2) Step-by-step reasoning
- Step 1: Determine which CSF function addresses investigation after an incident. The function concerned with actions taken once an incident is detected is Respond.
- Step 2: Map forensics tasks (evidence collection, timeline reconstruction, malware analysis) to CSF categories. These are part of “Analysis” and “Mitigation” within Respond.
- Step 3: Conclude that since forensics aids incident handling, it is recommended by Respond.

3) Calculations/intermediate steps
- No numerical calculations are needed. The logical mapping is: incident detected → activate response → perform forensics → inform containment/mitigation → recovery.

4) Why the correct answer is correct
- Respond explicitly includes analyzing incidents and conducting investigations to understand what happened and how to reduce impact. Forensics provides the technical analysis and evidence required for these Respond activities, making Respond the appropriate CSF function.

5) Why other options are incorrect
- Protect: Focuses on safeguards to prevent incidents (e.g., access control, maintenance), not post-incident investigation.
- Detect: Focuses on monitoring and discovery of potential cybersecurity events (e.g., IDS, logging), not the investigative follow-up.
- Recover: Focuses on restoring services and systems after an incident, not on forensic analysis to determine cause or support response.

6) Conclusion
Therefore, the correct CSF function that recommends performing computer or network forensics is Respond, which matches the provided answer: Respond.
