IT Pro Today ☛ Enhance Linux Kernel Security Using Lockdown Mode and Kernel Self-Protection
The Linux kernel is the open-source core of any Linux operating system. It runs protected processes in what is known as “kernel space,” or “kernel land,” located in ring 0 of the operating system. Kernel land is protected from user actions occurring in “user space” or “userland,” creating a security boundary that prevents accidental or malicious damage to essential system files. For user applications to interact with the kernel, they must make a system call to access its capabilities.
Securing the kernel is both critical and complex. The kernel must be resistant to various types of attacks, whether they originate locally or remotely. The challenge is compounded by the diversity of environments and architectures where Linux is deployed.
