Firejail is a SUID program that reduces the risk of security breaches by restricting the running environment of
untrusted applications using Linux namespaces and seccomp-bpf. 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.
