General Dynamics PitBull^®

What sets the originally developed for the US military operating system PitBull^® apart from everything known so far is that it does not have an all-powerful administrator role. Malware attempting to gain privileges through privilege escalation for further network spread fails at this point.

Furthermore, the 145 individual rights that replace the all-powerful administrator role enable fine-grained rights assignment and very individual sharing areas. This allows administrators to focus on their core task of administration instead of dealing with liability and culpability issues. For example, a backup manager only needs to secure files but does not need to read them. With such rights assignment, he cannot be held responsible for data leakage.

The security concept of PitBull^® is perfected by individually adjustable security contexts, the so-called compartments. These enable effective sandboxing and stop attackers at the entry point. They cannot spread further.
