Ricoh Aficio MP 3352 Security Target - Page 74

Page 73 of 91 (3) Complicate decoding of login password. FIA_UAU.7 displays dummy letters as authentication feedback on the Operation Panel and prevents the login password from disclosure. FIA_SOS.1 accepts only passwords that satisfy the minimum character number and password character combination specified for the Basic Authentication by the MFP administrator, and makes it difficult to guess the password. For the External Authentication, this depends on the settings for the External Authentication. FIA_AFL.1 does not allow the user who is unsuccessfully authenticated by the Basic Authentication for certain times to access to the TOE for certain period. For the External Authentication, this depends on the settings for the External Authentication. (4) Terminate login automatically. FTA_SSL.3 automatically logs out of the Operation Panel or a Web browser after no operation is performed from the Operation Panel or a Web browser for certain period and the auto logout time elapses. It also logs out the status of document data reception after the completion of document data reception from the printer driver or fax driver. The TOE terminates the session with RC Gate after completing the communication with RC Gate. (5) Management of the security attributes. According to FMT_MSA.1(b), the login user name and available function list of normal user are managed by the MFP administrator, and users are not allowed to operate the function type. FMT_MSA.3(b) sets the restrictive default value to the function type. By satisfying FDP_ACC.1(b), FDP_ACF.1(b), FIA_UID.1(a), FIA_UID.1(b), FIA_UID.2, FIA_UAU.1(a), FIA_UAU.1(b), FIA_UAU.2, FIA_ATD.1, FIA_USB.1, FIA_UAU.7, FIA_AFL.1, FIA_SOS.1, FTA_SSL.3, FMT_MSA.1(b) and FMT_MSA.3(b), which are the security functional requirements for these countermeasures, O.USER.AUTHORIZED is fulfilled. The function for 2600.1-SMI (F.SMI), selected SFR Package from the PP, is used in conjunction with the function whose access control is enforced by FDP_ACC.1(b) and FDP_ACF.1(b). Therefore, the access control for F.SMI is included with the access control by FDP_ACC.1(b) and FDP_ACF.1(b) and fulfilled. O.INTERFACE.MANAGED Management of external interfaces by TOE O.INTERFACE.MANAGED is the security objective to ensure that the TOE manages the operation of external interface according to the security policy. To fulfil this security objective, it is required to implement the following countermeasures. (1) Identify and authenticate the users prior to use the Operation Panel and LAN interface. FIA_UID.1(a) and FIA_UID.1(b) identify the persons who attempt to use the TOE from the Operation Panel or client computer on the network, and FIA_UAU.1(a) and FIA_UAU.1(b) authenticate the identified users. FIA_UID.2 identifies the persons who attempt to use the TOE from the interface for RC Gate communication, and FIA_UAU.2 authenticates the persons. (2) Automatically terminate the connection to the Operation Panel and LAN interface. FTA_SSL.3 terminates the session after no operation is performed from the Operation Panel or LAN interface for certain period. Copyright (c) 2011 RICOH COMPANY, LTD. All rights reserved.
