Overview

Finding ID Version Rule ID IA Controls Severity
V-73315 WN16-AC-000040 SV-87967r1_rule Medium
Description
A system is more vulnerable to unauthorized access when system users recycle the same password several times without being required to change to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes. The default value is "24" for Windows domain systems. DoD has decided this is the appropriate value for all Windows systems.
