The operating system must not allow an unattended or automatic logon to the system.


Overview

Finding ID Version Rule ID IA Controls Severity
V-67697 AOSX-11-000925 SV-82187r1_rule Medium
Description
When automatic logins are enabled, the default user account is automatically logged in at boot time without prompting the user for a password. Even if the screen is later locked, a malicious user would be able to reboot the computer in order to log in. Disabling automatic logins mitigates this risk.
