Limited access to overlays
Description
The Limited Access to Overlays (LAPW) feature introduced in
X11 Release 16 provides a greater degree of control of
password assignment and overlay access. In addition, it expands
tracking of switch access.
This feature provides additional security by allowing you to
define up to 100 LAPW passwords per system. The LAPW
password may be 4 to 16 alphanumeric characters in both
uppercase and lowercase. A maximum of four characters are
allowed in either Password 1 or Password 2.
How LAPW works
You can define access to specific overlays for each password
and specify a “Print-only” capability. You can also configure an
audit trail to record the date, time, and password used, and the
overlay programs accessed.
The system monitors failed logon attempts, compares the
number with a predefined threshold, and locks the entry port if
the threshold is exceeded. The Meridian 1 reports lock-out
conditions on all TTYs and provides a special report to the next
administrator who logs on.
