Rationale for Removing Dependencies on FIA_UID.1
Since this TOE employs FIA_UID.2, which is hierarchical to FIA_UID.1, the dependency on FIA_UID.1 is
satisfied by FIA_UAU.2 and FMR_SMR.1.
6.3.4 Security Assurance Requirements Rationale
This TOE is a commercially available product. It is assumed that it will be used in general offices, and that
the possibility of basic security attacks on this TOE exists. Architectural design (ADV_TDS.2) is adequate to
show the validity of commercially available products. A high attack potential is required for attacks that
circumvent or tamper with the TSF, which is not covered in this evaluation. The vulnerability analysis
(AVA_VAN.2) is therefore adequate for general needs.
However, protection of the secrecy of relevant information is required to make security attacks more difficult,
and it is important to ensure a secure development environment. Development security (ALC_DVS.1) is
therefore important also.
Based on the terms and costs of the evaluation, the evaluation assurance level of EAL3 is appropriate for this
TOE.
