FreeBSD – the unknown Giant

FreeBSD is a free, open-source and UNIX-like operating system. Though relatively unknown, it’s a performing and powerful work-horse, capable of coping with massive work-loads whilest remaining fast, ultra-stable and rock-solid. Blogging about FreeBSD and operating systems based on this versatile, safe and secure OS, I want to generate more interest in FreeBSD and its dependants. If you need a reliable, rock-solid and performing system for either your desktop or servers, consider FreeBSD!

Securing Network Services with FreeBSD Jails

November 24, 2009 by Gerard   Leave a comment

In this article by Christer Edwards, we will explore FreeBSD Jails. FreeBSD Jails are a kernel-level security mechanism which allows you to safely segregate processes within a sandbox environment. Jails are commonly used to secure production network services like DNS or Email by restricting what a process can access. In the case of a malicious attack on one service, all other Jailed processes would remain secure. FreeBSD Jails securely limits, in an administratively simple way, the amount of damage an attacker can do to a server.
