Check: SRG-OS-000075-GPOS-00043

General Purpose Operating System SRG: SRG-OS-000075-GPOS-00043 (in versions v3 r1 through v1 r6)

Title

Operating systems must enforce 24 hours/1 day as the minimum password lifetime. (Cat II impact)

Discussion

Enforcing a minimum password lifetime helps to prevent repeated password changes to defeat the password reuse or history enforcement requirement. If users are allowed to immediately and continually change their password, then the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse.
