What is the source of the acronym PAIN?
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.

I.e., its provenance?
Google shows only a few hits, indicating it is not widespread.
