The answer is capturing memory from the endpoint to find encryption keys. This is the most critical forensic step because encrypted data exfiltration, such as HTTPS traffic, uses session keys that exist in plaintext within a system’s volatile memory (RAM) during the active connection. By performing a memory capture before the endpoint is powered down, investigators can extract these keys and decrypt the exfiltrated data, directly addressing the core challenge of encrypted data exfiltration forensic step analysis. On the Certified Information Security Manager CISM exam, this question tests your understanding of incident response procedures and the priority of preserving volatile evidence over static disk analysis. A common trap is choosing network log review or disk imaging, which are secondary steps that cannot recover live encryption keys. Remember the mnemonic “RAM Reveals Keys” to recall that memory capture is the first and most vital action when dealing with encrypted data exfiltration.
CISM Incident Management Practice Question
This CISM practice question tests your understanding of incident management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a data breach investigation, the team discovers that an attacker exfiltrated data via encrypted HTTPS to a server abroad. Which forensic step is most critical?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Capture memory from the endpoint to find encryption keys
Capturing memory from the endpoint may reveal encryption keys used for the HTTPS session, allowing decryption.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Capture memory from the endpoint to find encryption keys
Why this is correct
Correct: Memory may contain the symmetric keys used for the HTTPS session.
Related concept
Read the scenario before looking for a memorised answer.
✗
Analyze firewall logs for the connection
Why it's wrong here
Firewall logs show metadata but not the exfiltrated content.
✗
Decrypt the traffic using the server's private key
Why it's wrong here
The server's private key is not available to the investigator.
✗
Trace the IP address to identify the attacker
Why it's wrong here
IP tracing is difficult and may not yield usable evidence.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
