And its close relative, system security.  You don't have to worry much about Putin's cronies if you're running RSX or RSTS/E.

I'm always amazed when I hear people complaining about the "security issues" of old mainframe systems that "urgently need to be replaced by modern systems".   You don't find viruses in OS/360, but they are a dime a dozen in the most popular modern OS, and new holes are created daily by hordes of modern sloppy programmers.
