This security setting determines whether pressing CTRL+ALT+DEL is required before a user can log on.
If this policy is enabled on a computer, a user is not required to press CTRL+ALT+DEL to log on. Not having to press CTRL+ALT+DEL leaves users susceptible to attacks that attempt to intercept the users' passwords. Requiring CTRL+ALT+DEL before users log on ensures that users are communicating by means of a trusted path when entering their passwords.
If this policy is disabled, any user is required to press CTRL+ALT+DEL before logging on to Windows.
Default on domain-computers: Enabled: At least Windows 8/Disabled: Windows 7 or earlier.
Default on stand-alone computers: Enabled.
Countermeasure:
Configure the Disable CTRL+ALT+DEL requirement for logon setting to Disabled.
Potential Impact:
Unless they use a smart card to log on, users will have to simultaneously press three keys before the logon dialog box will display.
