Host System Changes

Monitor Host System changes

Some pods need to change the host system or kernel parameters in order to perform administrative tasks, obvious examples are pods loading a kernel module to extend the operating system functionality, or pods managing the network.

However, there are also other cases where a compromised container may want to load a kernel module to hide its behaviour.

In this aspect, monitoring such host system changes helps to identify pods and containers that affect the host system.

Monitor Linux kernel modules

A kernel module is a code that can be loaded into the kernel image at runtime, without rebooting. These modules, which can be loaded by pods and containers, can modify the host system. The Monitor Linux kernel modules guide will assist you in observing such events.
