Security Management (TSF_FMT)
The TOE accomplishes security management for the security function, TSF data, and security
attribute.
Only U.ADMINISTRATOR can manage the security functions through the LUI (Local User
Interface) and RUI (Remote User Interface): security functions can be start and stop by
U.ADMINISTRATOR. The LUI is touch-screen based management service which is
provided by TOE. RUI is web-based management service using HTTP/HTTPS protocol.
TSF data and their possible operations are specified by U.ADMINISTRATOR.
Security attributes can be operated by U.ADMINISTRATOR.
Security Audit Data (TSF_FAU)
The TOE creates an audit record security audit event including job log, security event log,
and operation log. The audit data consist of the type of event, date and time of the event,
success or failure, log out and access of log data.
Only U.ADMINISTRATOR is authorized to view (or export) the audit data but even
U.ADMINISTRATOR shall not delete log data manually.
The TOE protects Security Audit Data stored on the hard disk drive. It prevents any
unauthorized alteration to the Security Audit Data, and when each log events exceeds the
maximum number, the TOE overwrites the oldest stored audit records and generates an audit
record of overwriting.
Image Overwrite (TSF_IOW)
The TOE provides Image Overwrite functions that delete the stored file from the MFP's hard
disk drive. The Image Overwrite function consists of Automatic Image Overwrite and
Manual Image Overwrite. The TOE implements an Automatic Image Overwrite to overwrite
temporary files created during the copying, printing, faxing and scanning (scan to e-mail,
scan to FTP, and scan to SMB task processes). The image overwrite security function can
also be invoked manually only by U.ADMINISTRATOR through the LUI. Once invoked, the
Manual Image Overwrite cancels all print and scan jobs, halts the printer interface (network),
overwrites the hard disk according to the procedures set by U. ADMINISTRATOR. If there
are any problems during overwriting, the Manual Image Overwrite job automatically restarts
to overwrite the remaining area.
