Readers are reminded that the certification of this product (TOE) is the result of maintenance, rather than an actual re-evaluation of the product. Maintenance only considers the affect of TOE changes on the assurance baseline (i.e. the original evaluated TOE); maintenance is not intended to provide assurance in regard to the resistance of the TOE to new vulnerabilities or attack methods discovered since the date of the initial certificate. Such assurance can only be gained through re-evaluation.
Using a security impact analysis of the changes made to the TOE, which was provided by the developer, the CCEVS has determined that the impact of changes on the TOE are considered minor and that independent evaluator analysis was not necessary. A summary of the results can be found in the Maintenance Report, which is written in relation to the product's original validation report and Security Target. Readers are therefore reminded to read the Security Target, Validation Report, and the Assurance Maintenance Report to fully understand the meaning of what a maintained certificate represents.
There have been no changes to the product or development environment.
The FDE AA cPP 2.0 was updated to FDE AA cPP 2.0E to account for changes to correct deficiencies identified in the initial validation of the cPPs in conjunction with the TOE evaluation, and incorporate all Technical Decisions. The Full Drive Encryption international Technical Community (FDE iTC) determined the impact of the changes to FDE AA cPP 2.0E were minor. The majority of the changes were typographical errors related to the conventions for indicating assignments and selections and there was one dependency SFR missing.
FDE AA cPP 2.0E added FMT_SMR.1: Security Roles, a previously missing dependency for FMT_MOF.1: Management of Functions Behavior and FMT_SMF.1: Specification of Management Functions. FMT_SMR.1 adds the requirement that the TOE Security Functionality (TSF) maintains roles for authorized users and be able to associate users with roles. The TOE already had this capability, as necessitated by FMT_MOF.1 and FMT_SMF.1. No additional evaluation activities for FMT_SMR.1 were added, as they were already covered in evaluation activities for FMT_MOF.1 and FMT_SMF.1. Therefore, no changes were required to the product.
The FDE EE cPP 2.0 was updated to FDE EE cPP2.0E The FDE iTC determined the impact of the changes to FDE EE cPP 2.0 E were typographical errors related to the conventions for indicating assignments and selections and did not impact the security functionality of the PP.
Only two technical decisions incorporated into FDE AA cPP 2.0E and FDE EE cPP2.0E were published after the initial evaluation, TD0383 and TD0384, neither of which is applicable to this evaluation. Therefore, no changes were required to the product.
The corrections to typographical errors were all incorporated into the ST and did not require any changes to the product.
