Authbind

authbind is a Linux utility that allows a network services which typically run as root to run as a regular user. It allows the user to bind to permit specific users and groups access to individual TCP and UDP ports numbered less than 1024, all of which would otherwise be reserved for the root user. This allows the user to run services that are prone to attack in such a way that they are not, in and of themselves, a valid means for an attacker to achieve privilege escalation.
