Assessment Title

Rule Text

The Recovery Console option is set to permit automatic logon to the system.

Description

Discussion Text

This is a Category 1 finding because if this option is set, the Recovery Console does not require you to provide a password and will automatically log on to the system, giving Administrator access to system files. By default, the Recovery Console requires you to provide the password for the Administrator account before accessing the system.
