# Firejail [![Build Status](https://gitlab.com/Firejail/firejail_ci/badges/master/pipeline.svg)](https://gitlab.com/Firejail/firejail_ci/pipelines/) [![Packaging status](https://repology.org/badge/tiny-repos/firejail.svg)](https://repology.org/project/firejail/versions) Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. 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 work in a SELinux or AppArmor environment, and it is integrated with Linux Control Groups. Written in C with virtually no dependencies, the software runs on any Linux computer with a 3.x kernel version or newer. It can sandbox any type of processes: servers, graphical applications, and even user login sessions. The software includes sandbox profiles for a number of more common Linux programs, such as Mozilla Firefox, Chromium, VLC, Transmission etc. The sandbox is lightweight, the overhead is low. There are no complicated configuration files to edit, no socket connections open, no daemons running in the background. All security features are implemented directly in Linux kernel and available on any Linux computer.

If you believe you have found one, please report it by emailing us at netblue30@protonmail.com ## Installing Try installing Firejail from your system packages first. Firejail is included in Alpine, ALT Linux, Arch, Chakra, Debian, Deepin, Devuan, Fedora, Gentoo, Manjaro, Mint, NixOS, Parabola, Parrot, PCLinuxOS, ROSA, Solus, Slackware/SlackBuilds, Trisquel, Ubuntu, Void and possibly others. The firejail 0.9.52-LTS version is deprecated. On Ubuntu 18.04 LTS users are advised to use the [PPA](https://launchpad.net/~deki/+archive/ubuntu/firejail). On Debian buster we recommend to use the [backports](https://packages.debian.org/buster-backports/firejail) package. You can also install one of the [released packages](http://sourceforge.net/projects/firejail/files/firejail), or clone Firejail’s source code from our Git repository and compile manually: ````` $ git clone https://github.com/netblue30/firejail.git $ cd firejail $ ./configure && make && sudo make install-strip ````` On Debian/Ubuntu you will need to install git and gcc compiler. AppArmor development libraries and pkg-config are required when using --apparmor ./configure option: ````` $ sudo apt-get install git build-essential libapparmor-dev pkg-config gawk ````` For --selinux option, add libselinux1-dev (libselinux-devel for Fedora). Detailed information on using firejail from git is available on the [wiki](https://github.com/netblue30/firejail/wiki/Using-firejail-from-git). ## Running the sandbox To start the sandbox, prefix your command with “firejail”: ````` $ firejail firefox # starting Mozilla Firefox $ firejail transmission-gtk # starting Transmission BitTorrent $ firejail vlc # starting VideoLAN Client $ sudo firejail /etc/init.d/nginx start ````` Run "firejail --list" in a terminal to list all active sandboxes. Example: ````` $ firejail --list 1617:netblue:/usr/bin/firejail /usr/bin/firefox-esr 7719:netblue:/usr/bin/firejail /usr/bin/transmission-qt 7779:netblue:/usr/bin/firejail /usr/bin/galculator 7874:netblue:/usr/bin/firejail /usr/bin/vlc --started-from-file file:///home/netblue/firejail-whitelist.mp4 7916:netblue:firejail --list ````` ## Desktop integration Integrate your sandbox into your desktop by running the following two commands: ````` $ firecfg --fix-sound $ sudo firecfg ````` The first command solves some shared memory/PID namespace bugs in PulseAudio software prior to version 9. The second command integrates Firejail into your desktop. You would need to logout and login back to apply PulseAudio changes. Start your programs the way you are used to: desktop manager menus, file manager, desktop launchers. The integration applies to any program supported by default by Firejail. There are about 250 default applications in current Firejail version, and the number goes up with every new release. We keep the application list in [/usr/lib/firejail/firecfg.config](https://github.com/netblue30/firejail/blob/master/src/firecfg/firecfg.config) file. ## Security profiles Most Firejail command line options can be passed to the sandbox using profile files. You can find the profiles for all supported applications in [/etc/firejail](https://github.com/netblue30/firejail/tree/master/etc) directory. If you keep additional Firejail security profiles in a public repository, please give us a link: * https://github.com/chiraag-nataraj/firejail-profiles * https://github.com/triceratops1/fe Use this issue to request new profiles: [#1139](https://github.com/netblue30/firejail/issues/1139) You can also use this tool to get a list of syscalls needed by a program: [contrib/syscalls.sh](contrib/syscalls.sh). We also keep a list of profile fixes for previous released versions in [etc-fixes](https://github.com/netblue30/firejail/tree/master/etc-fixes) directory. ````` ````` ## Latest released version: 0.9.64 ## Current development version: 0.9.65 Milestone page: https://github.com/netblue30/firejail/milestone/1 Release discussion: https://github.com/netblue30/firejail/issues/3696 ### Profile Statistics A small tool to print profile statistics. Compile as usual and run in /etc/profiles: ``` $ sudo cp src/profstats/profstats /etc/firejail/. $ cd /etc/firejail $ ./profstats *.profile Warning: multiple caps in transmission-daemon.profile Stats: profiles 1064 include local profile 1064 (include profile-name.local) include globals 1064 (include globals.local) blacklist ~/.ssh 959 (include disable-common.inc) seccomp 975 capabilities 1063 noexec 944 (include disable-exec.inc) memory-deny-write-execute 229 apparmor 605 private-bin 564 private-dev 932 private-etc 462 private-tmp 823 whitelist home directory 502 whitelist var 744 (include whitelist-var-common.inc) whitelist run/user 461 (include whitelist-runuser-common.inc or blacklist ${RUNUSER}) whitelist usr/share 451 (include whitelist-usr-share-common.inc net none 345 dbus-user none 564 dbus-user filter 85 dbus-system none 696 dbus-system filter 7 ``` ### New profiles: kdiff3, spectacle, chromium-browser-privacy, gtk-straw-viewer, gtk-youtube-viewer, gtk2-youtube-viewer, gtk3-youtube-viewer, straw-viewer, lutris, dolphin-emu, authenticator-rs, servo, tutanota-desktop, npm, marker, yarn, lsar, unar, agetpkg, mdr, shotwell, qnapi, guvcview, pkglog
