identify an authorized system administrator or general user.
By FIA_UAU.7, unauthorized disclosure of the authentication

is protected.
By FMT_MOF.1, the person who enables/disables TOE security
functions and makes functional settings is limited to system
administrator.
By FMT_MTD.1, the person who can make settings of TOE security
functions is limited to system administrator. Thus, only system

unauthorized person from using the TOE.
By satisfying the following security requirements, O.RESTRICT can be
realized:
By FIA_AFL.1 (1), successive attacks are prevented because the power
needs to be cycled when the number of key operator authentication
failures reaches the defined number of times.
By FIA_AFL.1 (2), successive attacks are prevented because the power
needs to be cycled when the number of SA authentication failures (at
local authentication) reaches the defined number of times.
By FIA_AFL.1 (3), when general user authentication fails, “incorrect
password” message is displayed, requesting password re-entry.
By FIA_AFL.1 (4), when SA authentication fails (at remote
authentication), “incorrect password” message is displayed, requesting
password re-entry.
By FIA_UIA.1 and FIA_UID.1, user authentication is performed to
identify an authorized general user and system administrator.
