Description: A hardened kernel is an operating system kernel that has been modified to enhance security by reducing vulnerabilities. This approach involves implementing various techniques and configurations that limit the possibilities of exploiting security flaws. The main features of a hardened kernel include permission restrictions, disabling unnecessary functions, and applying security patches more rigorously. These modifications are essential in environments where security is critical, such as servers and systems handling sensitive information. By hardening the kernel, the goal is to create a more robust barrier against cyberattacks, thereby ensuring greater integrity and availability of the system. This type of kernel is especially relevant in various operating systems, where security is a priority for system administrators and organizations relying on the stability and protection of their technological infrastructures.
