Samsung MFP Security Kit Type_B V1.5 Security Target



malignant codes are discovered, the TOE destroys the fax image. Fax

security functions follow the fax flow control policy.

The fax flow control policy is as follows:

Direct access to a received fax image from the fax modem to the user PC

through the internal network is not possible. Communication can be made

only through TOE.

The fax image received from the fax line is inspected first. When the data

is determined to be safe, the memory copy continues from the fax

memory area to the network memory area.

When a fax board is not installed, the information flow does not exist and

does not need the protection.

• Fax modem controller in the TOE is physically separated with MFP

controller, and fax function is logically separated with MFP functions.

• Fax interface only answers to the predefined fax protocol, and never

answers to any other protocol.

Fax modem controller provides only a standardized fax image format of

MMR, MR, or MH of T.4 specification. Therefore, the TOE does not answer

to malicious code or vicious executable files.

Relevant SFR: FDP_IFC.2(1), FDP_IFF.1(1)
