Seccomp

Security-enhanced Linux (SELinux) is a security module that provides an additional layer of protection for Linux systems. SELinux uses mandatory access control (MAC) to restrict the actions that users and processes can perform on the system. This can help to prevent unauthorized access to sensitive data and applications. SELinux is a powerful tool that can help to improve the security of Linux systems, but it can also be complex to configure and manage. One of the key components of SELinux is seccomp, which stands for secure computing mode. Seccomp is a kernel feature that allows processes to restrict the system calls that they can make. This can help to prevent processes from performing unauthorized actions, such as accessing sensitive files or executing malicious code.
