Quick Answer
The correct first step when investigating unusual outbound traffic is to check the server’s running processes and connections. This is because the analyst must gather situational awareness before taking any action; examining active processes reveals which application or service initiated the encrypted connection to the unknown external IP, confirming whether the traffic is malicious or a misconfigured legitimate service. On the ISC2 Certified in Cybersecurity CC exam, this question tests the Incident Response phase of “detection and analysis,” where premature containment (like blocking the IP) or reactive steps (like notifying management) can destroy forensic evidence or escalate an incident. A common trap is jumping to containment without verification, but the exam emphasizes that investigation always precedes action. Memory tip: think “Processes before blocks” — you cannot stop what you have not identified.
This CC practice question tests your understanding of security operations. 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.
A security operations center (SOC) analyst notices unusual outbound network traffic from a server that typically only receives connections. The traffic is encrypted and goes to an unknown external IP. Which step should the analyst perform FIRST?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Check the server's running processes and connections
Local investigation helps confirm compromise.
Power off the server
Why wrong: Powering off may destroy volatile evidence.
Block the outbound traffic at the firewall
Why wrong: Blocking may disrupt legitimate services if not confirmed.
Notify the system owner
Why wrong: Notification is important but not the first technical step.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Check the server's running processes and connections
Option D is correct because the analyst needs to gather more information before containing. Option A is too aggressive without confirmation. Option B is premature. Option C is reactive but less critical than investigation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
