Testing DLP with SSNs

Our DLP solution (by Trend Micro) claims to cross-reference SSNs against the actual census list of SSNs for valid SSNs. We would like to do some extnensive testing related to DLP. How can we test the SSN policy if it will only recognize and block actual, real SSNs?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you can try out this test sample http://www.identityfinder.com/kb/Getting-Started/110845
i was also thinking besides being positive testing, the coverage gauge should have the test set having below "variety"
- formatted SSN (in the form NNN-NN-NNNN, where N is any number from 0-9)
- unformatted SSN (in the form of NNNNNNNNN, where N is any number from 0-9, simply removes '-')
- invalid as SSN (in the form of faked SSN's and invalid sequences like 123-45-6789 or full sections containing all 0's)
- proximity matches such as a leading or trailing value (SSN, SS#, etc.)

probably regex for SSN is most of DLP friends and searching via bing below can generate more test sample if required. Do consider other carrier for SSN as content - not sure if it also detect that in image, binary etc or simply document format like Office, adobe etc...
