Firejail

Firejail

A SUID program, Firejail enhances security by isolating untrusted applications within a sandbox using Linux namespaces and seccomp-bpf. This lightweight tool operates on Linux systems with a 3.x kernel, enabling processes to maintain a private view of shared resources. With minimal overhead and no complex configurations, it effectively protects user privacy by restricting access to sensitive data across various applications, including popular web browsers and media players.
