Issue Description
The Network Interpretations Team (NIT) has issued a technical decision regarding handling of X.509 certificates when ssh-rsa is used for all remote communication in NDcPP v1.0 and FW cPP v1.0. Specifically, if all remote communication (both with remote servers and remote administrators) use SSH with "ssh-rsa" and the TOE does not use digital certificates for trusted updates then the FIA_X509_EXT.1, FIA_X509_EXT.2, FIA_X509_EXT.3 requirements are not applicable to any required services provided by the TOE. In this scenario, it does not make sense for the FIA_X509_EXT.1, FIA_X509_EXT.2, FIA_X509_EXT.3 requirements to be mandatory. Resolution
To align with NIT interpretation # 201610, the FIA_X509_EXT SFRs are moved to Annex B and are now selection-based requirements. For further information, please see the NIT interpretation at: https://www.niap-ccevs.org/Documents_and_Guidance/ccevs/NITDecisionRfi10.pdf Justification
