Firejail

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. 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

Current development version: 0.9.37

IPv6 support:

      --ip6=address
              Assign IPv6 addresses to the last network interface defined by a
              --net option.

              Example:
              $ firejail --net=eth0 --ip6=2001:0db8:0:f101::1/64 firefox

       --netfilter6=filename
              Enable the IPv6 network filter specified by filename in the  new
              network  namespace.  The  filter  file  format  is the format of
              ip6tables-save  and  ip6table-restore  commands.   New   network
              namespaces  are  created  using  --net  option. If a new network
              namespaces is not created, --netfilter6 option does nothing.
