Login control

You can change the login screen defaults for security reasons after a system installation.

Potential hackers can get valuable information from the default AIX login screen, such as the host name and the version of the operating system. This information would allow them to determine which exploitation methods to attempt. For security reasons, you may want to change the login screen defaults as soon as possible after a system installation.

The KDE and GNOME desktops share some of the same security issues. For more information about KDE and GNOME, refer to the Installation and migration.
