Look at the routing entries and ensure that no one has added or
updated any entries to run programs that you are not aware of.
A routing entry defines what a job does once it enters the subsystem. The
subsystem uses routing entries for all job types: batch, interactive, and
communications jobs. A routing entry specifies the following:
- The class for the job. Like job queue entries, the class that is associated
with a job can affect its performance but does not represent a security exposure.
- The program that runs when the job starts.
