I'm trying to create an audit rule to exclude all rsync actions when run by a process with a certain subject type (jcdx_fsbackup_t).
Our policy allows the action to happen, however as a result we generate a ton of audit data on file access and recreation at the target point. Anyone have a good idea of how to discard all these events? Ideally the caller would send in a self-generated event such as "ryncing rick/src2/ to /temp-home" or similar. This is for a dedicated file backup procedure. Obviously I do not want to discard all rsync events, just when launched by our trusted program. Nor would I really want all that program's events discarded since I want it to be able to submit proactive events which summarize its behavior. Below are some event samples. Other ideas are welcome also if my approach is myopic/flawed.
