CS0-003 Incident Response and Management Practice Question
During a forensic investigation of a compromised Linux server, the analyst needs to acquire memory for analysis. The system is running and the analyst cannot power it off. Which tool is MOST appropriate for acquiring memory in this scenario?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
LiME
LiME (Linux Memory Extractor) is a tool designed for acquiring memory from Linux systems while they are running, and it can be loaded as a kernel module without shutting down.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
LiME
Why this is correct
LiME (Linux Memory Extractor) is a kernel-mode tool specifically designed for volatile memory acquisition on Linux systems. It operates as a Kernel Loadable Module (LKM), allowing investigators to capture full RAM dumps with minimal footprint and high integrity, even bypassing restrictions that might block user-space memory access.
- ✗
FTK Imager
Why it's wrong here
FTK Imager is a widely used forensic tool primarily designed for Windows environments to perform disk imaging and logical file extraction. While it does support volatile memory acquisition on Windows systems, it cannot be natively executed on a live Linux server to capture its RAM.
- ✗
WinPmem
Why it's wrong here
WinPmem is an open-source physical memory acquisition tool specifically engineered for Microsoft Windows operating systems. It utilizes a dedicated kernel driver to read physical memory, making it completely incompatible with and unable to run on Linux architectures.
- ✗
dd
Why it's wrong here
The dd utility is a standard command-line tool used for copying and converting raw data, typically utilized for creating bit-stream disk images of storage drives. It is not suitable or safe for live memory acquisition on modern Linux kernels, as reading directly from /dev/mem or /dev/kmem is heavily restricted or disabled for security reasons.
