Detect ABA_RoutingNumber

[masonjarrod]

An ABA routing number is a nine-digit code that is less personal than one's Social Security number. The routing number was created by the American Bankers Association (ABA) in 1910 and then later adopted by the industry in 1911 (“Routing Number Policy & Procedures | American Bankers Association”).

ABA_Routing Number is a number in the format of AAAA (Federal Reserve Routing Symbol) YYYYY (ABA Institution Identifier) C (Check Digit).

Detection Steps:

Create a regex pattern to match the Routing numbers (same format as above).
Test the pattern with sample valid and invalid numbers.
Add this check to our PII scan system.
If a number is found, we will then mask or block it in any sort of inputs, similar to the Medicare database logs.

Hey Jarrod, good start with the background and structure. I think the description could focus more on why protecting routing numbers matters (like preventing fraud). Also, detection steps are missing. Overall solid, just needs more focus on security and detection.
