Keeping Unix Systems Up To Date

Many security problems arise from systems being installed correctly but then being neglected. New security holes are found from time to time and it is ssential that patches and updates be regularly applied to a system if it is to be secure.

Unix Support provides the updates and patches for Red Hat Linux, Debian Linux, Solaris, Irix and Compaq Tru64 Unix. We also provide help for Solaris, Red Hat Linux and Debian Linux for systems to be compared against the available updates and patches.
