Significant progress toward general acceptance of applying mandatory access control to systems has been made recently. Security Enhanced Linux (SELinux), in particular, has been enabled by default in some Linux distributions for several years. However, current SELinux deployments only effectively control a single system. Inter-system and remote resource access control capabilities are starting to appear in SELinux, but extending policy management capabilities to cover these networked systems remains an open problem. This paper discusses issues that must be addressed to support security policies distributed across a network, including policy development changes needed to be able to express a coherent security policy for a network of systems, managing the distribution of a multi-system policy, and synchronizing policy updates, and compares options to provide this support.
