| Description | ||||
| Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements. | ||||

Check Text (C-223508r1001119_chk)
From an ACF command screen enter:
SET CONTROL(GSO)
LIST PSWD
If "PSWDXHIST" is not specified, this is a finding.
If "PSWDXHIST#" is set to "5" or greater, this is not a finding.
Fix Text (F-25169r500658_fix)
Configure Password option "PSWXHST" is coded and "PSWXHST#" is "5" or greater.
