I've seen, for many years, the acronym "CAIN", where the C is 
"Confidentiality". I think that was in the Orange Book.

There's also, historically, an R for "Robustness" or "Reliability" in many 
military contexts, instead of the N for Nonrepudiation. That is, protection 
from denial-of-service attacks.

Lastly, the A is often Authorization rather than Authentication, since 
integrity implies identification of the source.

The first time I recall seeing PAIN was just a few weeks ago, in postings 
by Lynn.

I don't know if that helps, because I certainly got mightily confused while 
writing it.

Greg.
