With every passing day new operating systems come to live, new Distros are release, and yet they don’t implement a maximum security. With a machine available on the internet for public or private use, is very important to keep in mind that no matter how many measures of security are taken, the machine or the service you provide will always be at risk. As many know it is very hard to keep up to date with daily new releases, patches and of course exploits that can seriously compromise our system or services. Reason why many administrators decide to move a step ahead towards security and implement a jail that contains each service they provide.

Chroot or jailing a service that complies with security policies and at least the minimum security measures is ideal to limit the possible access an attacker can have if the service get compromised. When putting the service in a jail an attacker will not be allow to move out of this jail, which will minimize the data getting compromised and limit the access the attacker could have.
