Security Objectives
Security Functional Requirements Rationale
By FIA_UAU.7, unauthorized disclosure of the authentication
information (password) is prevented because the authentication feedback
is protected.
O.USER
O.USER is the objective that identifies the TOE user and allows only the
authorized user to retrieve, and delete the document data and to change
password.
By satisfying the following security requirements, O.USER can be
realized:
By FDP_ACC.1 and FDP_ACF.1, user authentication is performed. Only
authorized user is allowed to operate the objects.
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_ATD.1 and FIA_USB.1, each role of key operator, SA, and
general user is maintained and only the authorized users are associated
with the subjects.
By FIA_SOS1, the minimum length of password for SA and general user
is limited.
By FIA_UAU.1 and FIA_UID.1, user authentication is performed to
identify an authorized general user and system administrator.
By FIA_UAU.7, unauthorized disclosure of the authentication
information (password) is prevented because the authentication feedback
is protected.
By FMT_MSA.1, the query, modify, deletion, and creation of security
attributes are managed.
By FMT_MSA.3, the suitable default values are managed.
By FMT_MTD.1, the setting of password for key operator is limited to
key operator, that for SA is limited to key operator and SA, and that for
general user is limited to system administrator and the general user
(when it is his/her own).
By FMT_SMF.1, TOE security management functions are provided for
authorized users.
