Essential System Tools: Firejail – Excellent Security Sandboxing
This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For details of all tools in this series, please check the table at the summary page of this article.
For this article, we’ll look at Firejail, a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, Linux capabilities and seccomp-bpf.
What are namespaces? They are a method of detaching processes from a specific layer of the kernel and assigning them to a new layer. The processes see a different file system root with no access to the original file system. This concept is extended to the other operating system layers. A specific process therefore resides in a virtual operating system.
