Description
Some adversaries launch attacks with the intent of executing code in non-executable regions of memory or in memory locations that are prohibited. Security safeguards employed to protect memory include, for example, data execution prevention and address space layout randomization. Data execution prevention safeguards can either be hardware-enforced or software-enforced with hardware providing the greater strength of mechanism.
Examples of attacks are buffer overflow attacks.
Determine if critical core programs to the operating system are identified.
If the Mainframe Product does not protect critical core programs, this is a finding.
If an external security manager (ESM) is in use verify that the ESM is configured and/or has rules to protect critical core programs. If it does not, this is a finding.
Fix Text (F-5854r851352_fix)
Configure the Mainframe Product to identify critical core programs to the operating system for protection in accordance with applicable access control policies.
This can be accomplished by an external security manager (ESM). Configure the ESM to restrict access to these critical core programs to appropriate users in accordance with applicable access control policies.
