    The exit points are documented to allow user-created programming, and some examples as well as some free-ware offerings can be found around the Internet. There are various caveats, though, that can take some time and experience to work through.

    Because of the time that it can take and the vulnerabilities that can be created through inexperience, it's almost always both cheaper and safer to pick a commercial offering.

    We only ever had one user that would routinely abuse the system, so we always knew where to look. We changed his password to expire every 7 days, after that he got the hint and started to behave better.

    IBM has some examples of exit programs. We use one of theirs to protect FTP access. I believe there is another one for ODBC.
    If you want to just purchase a package, check out KISCO's offering. Their package is quite comprehensive and reasonably priced. It would save you a lot of time.

    Time is saved not only in initial coding and testing. Exit program behavior needs to be revalidated after various PTFs and especially fully tested before OS upgrades. Vendors of the packages will generally get test versions of new OS releases before GA, and they ensure that their programming is updated before customers upgrade their systems.
