7.9 Software Verification Function

The Software Verification Function is to verify the integrity of the executable codes of the MFP Control

Software and FCU Control Software and confirm that these codes can be trusted.

FPT_TST.1

The TOE verifies software at the TOE start-up.

The TOE verifies the integrity of the MFP Control Software first by using the hash and then by checking the

certificate. If the hash does not match its original value or the certificate verification fails, the TOE displays

the error message and becomes unavailable. If the hash matches its original value and the certificate is

verified, the TOE becomes available. The TOE also verifies the integrity of the audit log data files.

The TOE outputs the information used for integrity verification so that the integrity of the FCU Control

Software can be verified. To check the integrity of the FCU Control Software, the information the TOE

outputs will be compared with the information described in the guidance documents, so that the integrity of

the FCU Control Software can be verified.

7.10 Fax Line Separation Function

The Fax Line Separation Function is to receive only faxes as input information from telephone lines so that

unauthorised intrusion from telephone lines can be prevented. This function also can be used to prohibit

transmissions of received faxes so that unauthorised intrusion from telephone lines to the LAN can be

prevented.

FPT_FDI_EXP.1

The TOE receives fax data only as input information from telephone lines. If any communication that does

not comply with the fax protocol is performed, the line is disconnected. Since the TOE is set to prohibit

forwarding of received fax data during installation, received fax data will not be forwarded.
