The Mainframe Product must maintain a separate execution domain for each executing process.

Description
Applications can maintain separate execution domains for each executing process by assigning each process a separate address space. Each process has a distinct address space so that communication between processes is performed in a manner controlled through the security functions, and one process cannot modify the executing code of another process. Maintaining separate execution domains for executing processes can be achieved, for example, by implementing separate address spaces. An example is a web browser with process isolation that provides tabs that are separate processes using separate address spaces to prevent one tab crashing the entire browser. This requirement also applies to Zero Trust initiatives.

Who does this work

13 NICE work roles and 8 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-205586r1137804_chk)

If the Mainframe Product has no function or capability for multi-session operation, this is not applicable. If the Mainframe Product is not configured to uniquely define and engineer each session to execute independently of any other session, this is a finding.

Fix Text (F-5852r299986_fix)

Configure the Mainframe Product to uniquely define and engineer each session to execute independently of any other session.
