The Linux kernel is a robust and adaptable foundation for modern computing, supporting exceptional performance, scalability, and security. Tools like SELinux, AppArmor, and seccomp provide kernel-level security to safeguard applications and systems. The kernel's integration of file systems such as ext4, Btrfs, and ZFS offers high-performance storage solutions. FUSE enables custom file system development in user space. These capabilities make the Linux kernel suitable for demanding applications like containerization, virtualization, security, and high-performance networking.
