We filter for SSN, but it does not catch everything. I realize a consecutive 9 digit number would be a bad idea and we do not have a rule in place for that anyway. What I do need is a way to catch SSN in the following format: xxx-xx-1234 or xxx-12-3456. We use the built-in DLP rule for SSN, but it does not catch those formats. It only catches of it is in the form of 123-45-6789. We have a different rule that will look for the letters SSN or Social Security, etc, but those are not always included in the email. How do I go about this? I presume it would have to be a RegEx policy customization, but this is not something I have done before. So if someone is doing this and it is working, please give me the "for dummies" version of how to implement it.
Thanks in advance
