I haven't checked just yet, but I believe the password length information is within the OF A 500-27 and possibly within the CNSSI 1253 Appendix J (depending on customer requirements.

SP 800-53 IA-5 (1)(a) globalized to 14+ due to the LM hash factor?

All,

 

While we’re on the topic of source policies, I’ve been trying to track down the reasoning for the 15 character minimum.  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?
