The answer is to perform memory forensics before containment. This is the correct choice because when a host has been communicating with a known C2 server for two weeks, the attacker has likely established deep persistence through rootkits, injected code, or kernel-level hooks that exist only in volatile memory. Disconnecting or shutting down the host immediately would destroy this critical evidence, making it impossible to analyze the full scope of the compromise, including the specific malware variant and lateral movement artifacts. On the Systems Security Certified Practitioner SSCP exam, this scenario tests your understanding of the incident response lifecycle, specifically the balance between containment and evidence preservation. A common trap is to assume immediate disconnection is always best, but for long-term C2 infections, memory forensics before containment is prioritized to capture running processes and network connections. Remember the mnemonic: “Don’t yank the plug, grab the RAM first.”
SSCP Incident Response and Recovery Practice Question
This SSCP practice question tests your understanding of incident response and recovery. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 company's IDS generated an alert for a suspicious outbound connection to a known C2 server. The incident team discovers the host has been communicating for 2 weeks. Which containment strategy is most appropriate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform memory forensics before disconnecting
Performing memory forensics before disconnecting (A) is the most appropriate containment strategy because the host has been compromised for two weeks, meaning the attacker may have deployed rootkits, injected malicious code into system processes, or established persistence mechanisms that reside only in volatile memory. Disconnecting or shutting down the host immediately would destroy this volatile evidence, hindering the incident response team's ability to identify the full scope of the compromise, including the specific malware variant, C2 communication methods, and any lateral movement artifacts. Memory forensics allows the team to capture running processes, network connections, and loaded kernel modules, which are critical for understanding the attacker's tactics and preventing future incidents.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Perform memory forensics before disconnecting
Why this is correct
Memory capture preserves evidence of running processes and network connections.

✗
Block the C2 IP at the perimeter
Why it's wrong here
This prevents further C2 communication but does not contain the host itself.
✗
Shut down the host
Why it's wrong here
Shutdown destroys volatile data and may trigger anti-forensics.
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose immediate disconnection (D) or IP blocking (B) as a quick containment action, failing to recognize that preserving volatile evidence is a higher priority in a long-term compromise to ensure a complete forensic analysis and effective remediation.
Detailed technical explanation
How to think about this question
Memory forensics tools like Volatility or Rekall can extract artifacts such as hidden processes (via DKOM), injected DLLs, and network socket information from a memory dump, which are often not visible to traditional disk-based forensic tools. In a real-world scenario, an attacker may use process hollowing or reflective DLL injection to run payloads entirely in memory, leaving no trace on disk; capturing this volatile data before containment is the only way to recover the malicious code. Additionally, the two-week communication window suggests the attacker may have established a persistent backdoor using techniques like scheduled tasks or WMI event subscriptions, which can be identified in memory but would be lost if the system is powered off.

Real-world example
How this comes up in practice
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.
