Kernel Modules

Overview

Evidence: Kernel Modules Description: Collect Kernel Modules Category: System Platform: Linux Short Name: kernelmo Is Parsed: Yes Sent to Investigation Hub: Yes Collect File(s): No

Background

Linux kernel modules provide information about loaded kernel extensions and drivers. This data is essential for understanding system kernel configuration and detecting unauthorized kernel modifications.

Data Collected

This collector gathers structured data about kernel modules.

Kernel Modules Data

Field	Description	Example
ID	Primary key (auto-increment)	1
Name	Module name	nf_conntrack
Size	Module size in bytes	123456
UsedBy	Number of references	2
Dependencies	Module dependencies	nf_conntrack_ipv4
State	Module state	Live
Address	Module memory address	0xffffffffc0000000

Collection Method

This collector parses the necessary data from the kernel_modules table.

This collector collects files from the following locations:

• /proc/modules

• /lib/modules/

Usage

This evidence is crucial for forensic investigations as it provides kernel module information. It helps investigators understand kernel configuration, detect unauthorized kernel modifications, and investigate kernel-based attacks. The data can reveal loaded modules, kernel extensions, and potential kernel vulnerabilities. Analysts can use this information to identify kernel compromises, trace kernel activities, and assess kernel security posture.

Notes

This data may contain sensitive information that should be handled according to data protection requirements. Ensure proper chain of custody is maintained during collection and analysis.
