Castle Linux

Castle Linux is a Russian distribution of GNU/Linux, based on the distribution French Mandrake Linux and inspired by the project Openwall Linux. It is strongly directed safety.

Castle Linux is developed by the Muscovite company ALT Linux TEAM and draws its name from the Château , of Franz Kafka. In this novel, a land-surveyor tries to penetrate in a castle without success, which constitutes an obvious reference to the failure of the intrusions on a computing system based on Castle Linux.

The distribution, indeed, innovated by proposing various chrootés services (the user connected via the service believes being in the root ( root ) of the system, whereas it is actually in a preset repertory above which it cannot go up). In same optics, it has also included the software of control based on access rules to the core Linux RSBAC (for Rule Set Based Access Control ), and this for one time when this kind of characteristics was reserved to the specialists in safety.

The characteristic of RSBAC is to create a “super user” ( superuser ), named officer (the “officer” of the system). This user is the only one with being able to control the system fully, by the means of access rules between the processes and the Linux core. Thus, the access to the critical parts of the system can be restricted with this only user, while the user root (who is normally the super user on the systems Unix) can itself be imprisoned in a chroot .

Taking a more commercial orientation in 2001, this distribution does not remain about it less today a reference as regards safety and even seems to return to its original intention.
