The Distributed Console Access Facility (DCAF) Console must be restricted to only authorized personnel.

Rule version HLESC080 · STIG v2 · 2026-08-31

Discussion

The DCAF Console enables an operator to access the ESCON Director Application remotely. Access to a DCAF Console by unauthorized personnel could result in varying of ESCON Directors online or offline and applying configuration changes. Unrestricted use by unauthorized personnel could lead to bypass of security, unlimited access to the system, and an altering of the environment. This would result in a loss of secure operations and will impact data operating integrity of the environment. NOTE: Many newer installations no longer support the ESCON Director Application. For installations not supporting the ESCON Director Application, this check is not applicable.

Check

If the ESCON Director Application is present, verify that sign-on access to the DCAF Console is restricted to authorized personnel, otherwise, this check is not applicable.

If sign-on access to the DCAF Console is not restricted, this is a finding.

Fix

Review access authorization to DCAF Consoles. Ensure that all personnel are restricted to authorized levels of access.

Remote access to the LAN may be provided through DCAF via a LAN or modem connection. DCAF passwords should be implemented to prevent unauthorized access.
