Linux Kernel and Loadable Modules
Explore the role of the Linux kernel and loadable modules in system control. Understand how to check kernel status, manage loadable modules, and safely tune kernel settings. This lesson enhances your ability to handle kernel interactions carefully during web application penetration testing.
We'll cover the following...
