| Security functions are defined as "the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based." If the security functions were to be undermined, the MDM server could be compromised.
MDM server administrators can increase the assurance in security functions by employing well-defined security policy models, structured, disciplined, and rigorous hardware and software development techniques, and sound system/security engineering principles. The MDM server element must isolate security functions from non-security functions by means of an isolation boundary (implemented via partitions and domains) controlling access to and protecting the integrity of, the hardware, software, and firmware performing those security functions. The MDM server must maintain a separate execution domain (e.g., address space) for each executing process. |
