The Generic Software Wrappers Toolkit allows you to wrap closed-source applications to constrain or transform their behavior. Wrappers are written that intercept system calls and other system events, and allow you to deny, transform, log, or augment the system events. They are written in a custom language that abstracts away many of the gritty issues, allowing the wrapper author to concentrate on policy. Sample wrappers include dbfencrypt, which provides transparent access to "encrypted" files; controlledx, which limits the programs a process can execute; and id-seq, a trainable sequence-based intrusion detection wrapper.
