Security Mechanisms

Security Mechanisms (How)

Will be needed to implement the logical security services from the layer above (logical). Different mechanisms will be used in different contexts

for the same service, and an indication of where each selected mechanism should be used.

Security mechanisms are encryption, access control, digital signatures, virus

scanning, etc. and the physical machines upon which these mechanisms will be hosted.

Check Table 12-1, pages 343-347, to see and example of mapping security mechanisms to security services.
