I’m sure it’s not conjured from nowhere, but the only policy I’ve found that dictates minimum password length [IA-5(1)] is CNSSI-1253 (Dated Mar 2014) that says 12 characters minimum. “A case sensitive 12-character mix of upper case letters, lower case letters, numbers and special characters in including at least one of each.” I checked the classified and intelligence overlays, and didn’t see any reference to the control. So, can anyone point me to a policy that leads to 15 characters being in the STIG? Tom A.
