SC-39 Process Isolation

System and Communications Protection

Low Moderate High

Description

Maintain a separate execution domain for each executing system process.

Supplemental Guidance

Systems can maintain separate execution domains for each executing process by assigning each process a separate address space. Each system 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.
