Fuji Xerox C2265/C2263
Security Functional Requirements Rationale
protect User Document Data on the internal network between TOE and IT
products from any threat.
Thus, the functional requirements related to this objective are surely
fulfilled.
O.FUNC.NO_ALT is the objective to protect User Document Data of TOE
from unauthorized alternation.
This security objective can be realized by satisfying the following security
functional requirements:
Only the authorized user is permitted to operate User Document Data by
conducting the user identification by the following:
FDP_ACC.1(a),FDP_ACC.1(h), FDP_ACF.1(a),FDP_ACF.1(h), and
FIA_UID.1.
By FMT_MSA.1(a), FMT_MSA.1(h), the query, modification, deletion, and
creation of security attributes are managed.
By FMT_MSA.3 (a), FMT_MSA.3 (h), the suitable default values are
managed.
By FMT_SMR.1, the role of key operator, SA , system administrator and
general user is maintained and associated with the key operator, SA ,
system administrator and general user.
By FMT_SMF.1, TOE security management functions are provided for
system administrator.
By FTP_ITC.1, communication data encryption protocol is supported to
protect User Document Data on the internal network between TOE and IT
products from any threat.
Thus, the functional requirements related to this objective are surely
fulfilled.
O.PROT.NO_ALT is the objective to protect TSF Data of TOE from
unauthorized alternation.
This security objective can be realized by satisfying the following security
functional requirements:
By FIA_UID.2, only the authorized system administrator is permitted to
handle TSF Data by conducting the user identification.
By FMT_MOF.1, the user who enables/disables TOE security functions and
makes functional settings is limited to system administrator.
By FMT_MSA.1(a), FMT_MSA.1(b), FMT_MSA.1(c),FMT_MSA.1(d),
FMT_MSA.1(e), FMT_MSA.1(f),FMT_MSA.1(g), FMT_MSA.1(h),
modification, deletion, and creation of security attributes are managed.
By FMT_MTD.1 (a), the person who can make settings of TOE security
functions is limited to system administrator. Thus, only system
administrators can query and modify TOE setting Data.
