The Cuckoo's Egg
Was a very good read, particularly for its day. I was involved with a military R&D center at the time and was sys admin for about four local systems. It was enlightening at the time to realize how vulnerable many allegedly "secure" systems were. This was particularly true if the mainfraime was, for example, a Digital Equipment Corp (DEC) computer. The contractor techs routinely left the system's "back door" access set to "Field" and "Service" respectively for the username and password! By the way, Stoll pointed this out in his book.
While the story is "old," the one point this article makes, although poorly, is that much of the same thing is going on today - multiplied many times over.
For those of you who haven't read it, The Cuckoo's Egg is, at the very least, an excellent detective story. At best, it can be an eye-opener even today.
