From: "Joseph S. D. Yao" <jsdy () cospo osis gov> Similarly, chrooting is a deterrent, not a guarantee (and, especially, not as much of a guarantee as it used to be). Yes, it would be nice if it compartmented more than it did. In fact, that's an interesting idea: as chroot partitions the file system, perhaps there might be other services to partition off other kernel services? For the future.
All B1 systems do this now, and B1 versions are available for most commercial OS products. Other products, such as Argus's Decaf do partitioning as well, but without the B1 mechanisms. This is the main argument used for B-level security. paul --------------------------------------------------------- Paul McNabb Argus Systems Group, Inc.
