Firejail is a SUID security sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table.
Firejail can sandbox any type of processes: servers, graphical applications, and even user login sessions. Written in C with virtually no dependencies, it should work on any Linux computer with a 3.x kernel version. Debian, Ubuntu, Mint, OpenSUSE, and Fedora packages are provided. An Arch Linux package is maintained in AUR.
- Linux namespaces support: mount, UTS, IPC, PID, network
- Process separation
- Filesystem support: local filesystem mounted read-only, chroot filesystem, and overlay filesystem
- Support for running multiple sandboxes on top of the same filesystem
- Server sandboxing
- GUI application sandboxing
- User login session sandboxing
- Private mode
- Filesystem security profile support; default security profiles for Firefox, Midori and Evince
- Bash, zsh and csh shell support
- Seccomp support
- Extensive networking support
- Extensive monitoring support
- Source: Extract the the files from the archive and run ./configure && make && sudo make install in the archive directory. Firejail only needs libc and POSIX threads (libpthreads) for compilation, no additional libraries are required.
