Security features range from boot protection, discretionary access control
, key management, electronic signature, and DES-based data encryption and authentication.
The criteria for an E2/F-C2 rating are similar to those of the NCSC and require essentially the same functions -- identification and authentication, discretionary access control
, audit and object reuse.
Along with features that meet the B1 MDIA requirements, Trusted UNICOS provides functional aspects of higher-level requirements, including B3 discretionary access control
(DAC), B2 trusted facility management, and A1 trusted distribution, Falde said.
