Title

Windows Server 2025 users must be prompted to authenticate when the system wakes from sleep (plugged in).

Control

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Power\PowerSettings\0e796bdb-100d-47d6-a2d5-f7d2daa51f51\ Value Name: ACSettingIndex Type: REG_DWORD Value: 0x00000001 (1)

Discussion

A system that does not require authentication when resuming from sleep may provide access to unauthorized users. Authentication must always be required when accessing a system. This setting ensures users are prompted for a password when the system wakes from sleep (plugged in).
