Which TWO host-based analysis techniques are most effective for detecting fileless malware?
⚠ Common exam trap
Cisco often tests the distinction between host-based and network-based analysis techniques, and the trap here is that candidates may select network traffic analysis (B) because it can detect fileless malware's network activity, but the question specifically asks for host-based techniques, making B incorrect.

Correct answer & explanation
✓
Process memory analysis to detect injected code
Process memory analysis (A) is effective because fileless malware resides in memory without writing to disk, so examining running processes for injected code, suspicious memory regions, or anomalous API calls can directly detect the malicious payload. PowerShell script block logging (E) captures the full text of PowerShell commands executed, including obfuscated or encoded scripts that fileless malware often uses to load payloads directly into memory, making it a powerful host-based detection technique.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Process memory analysis to detect injected code
Why this is correct
Fileless malware often injects code into memory.
- ✗
Network traffic analysis
Why it's wrong here
Network analysis is not host-based; it's network-based.
- ✗
Signature-based file scanning
Why it's wrong here
Fileless malware has no file to scan.
- ✗
Registry analysis for persistence
Why it's wrong here
Fileless may still use registry, but not primary detection technique.
- ✓
PowerShell script block logging
Why this is correct
Many fileless attacks use PowerShell; enabling logging captures commands.
