Executive Summary The purpose of this report is to document the results of the evaluation of SecureSwitch® Dual Network Switch, Model #5000600, a product of Market Central, Inc., of Pittsburgh, PA.1 This report is not an endorsement of the product by any agency of the United States Government, and no warranty of the product is either expressed or implied. Evaluation at EAL42 of SecureSwitch® Dual Network Switch, Model #5000600, a stand- alone, all-hardware product was performed by the COACT, Inc.3 CAFE Laboratory of Columbia, MD. The project, which also involved the evaluation of the applicable Security Target (ST), was completed on October 31, 2001. The SecureSwitch Dual Network Switch, Model #5000600 TOE is a mechanical switch assembly that controls the connections to two separate networks. The TOE provides the capability to connect to only one of the networks at any given time, and prevents crosstalk, or bleed-over, from one network to the other. The TOE consists of two separate mechanical switches, connected with a non-metallic bar that prevents both switches from being either open or closed at the same time. One switch must be open and one closed. The housing of the TOE is also non-metallic, to prevent conduction of any signal between the two separate networks. Additionally, internal to the TOE, each of the switch mechanisms is encased in a composite copper/iron shielding to prevent any electromagnetic coupling of the two networks. The non-metallic housing of the TOE is assembled with tamper-resistant screws to reduce the possibility of a user gaining physical access to the composite copper/iron shielding, switches, and/or internal wiring. The SecureSwitch® Dual Network Switch, Model #5000600 does not claim conformance to any Protection Profile (PP). The Security Target (ST) for the SecureSwitch® Dual Network Switch, Model #5000600, is contained within the COACT, Inc. document Market Central SecureSwitch® Security Target, V1.3, dated October 29, 2001 [STV1.3]. The ST is compliant with the Specification of Security Targets requirements found within Annex C of Part 1 of the CC [CCV2.1P1]. The SecureSwitch® Dual Network Switch, Model #5000600 TOE has been shown to be compliant with the TOE security functional requirements; the IT security functional requirements; and the security assurance requirements identified within the ST. 1 Market Central, Inc., 500 Business Center Drive, Pittsburgh, PA 15205-1333.

The validation team followed the procedures outlined in the CCEVS Publication Number 3, Guidance to Validators of IT Security Evaluations [CCEVS3]. The validation team concluded that the evaluation verdicts of Pass for both the ST and the TOE. 2. Identification Name and model number of evaluated product: SecureSwitch® Dual Network Switch, Model #5000600 Developer: Market Central Inc. 500 Business Center Drive Pittsburgh, PA 15205-1333 Voice: (412) 494-2800 TOE Description: 6 The SecureSwitch Dual Network Switch, Model #5000600 TOE is a mechanical switch assembly that controls the connections to two separate networks. The TOE provides the capability to connect to only one of the networks at any given time, and prevents crosstalk, or bleed-over, from one network to the other. The TOE consists of two separate mechanical switches, connected with a non-metallic bar that prevents both switches from being either open or closed at the same time. One switch must be open and one closed. The housing of the TOE is also non-metallic, to prevent conduction of any signal between the two separate networks. Additionally, internal to the TOE, each of the switch mechanisms is encased in a composite copper/iron shielding, to prevent any electromagnetic coupling of the two networks. The non-metallic housing of the TOE is assembled with tamper-resistant screws, to reduce the possibility of a user from gaining physical access to the composite copper/iron shielding, switches, and internal wiring. Images of the SecureSwitch Dual Network Switch, Model #5000600 TOE are shown in Figure 1 and Figure 2. Figure 1. SecureSwitch®, front view. Figure 2. SecureSwitch®, rear view. 7 3. Security Policy The security policy for the SecureSwitch® Dual Network Switch, Model #5000600 TOE, a mechanical switch assembly that controls connections to two separate networks, is as follows: 1. The networks are identified as Network A and Network B. Both Network A and Network B interface with the TOE via RJ45 connectors located at the rear of the TOE (see Figure 2). 2. The TOE allows signals from either Network A or Network B to pass through it. The user of the TOE selects either Network A or Network B as the signal source via switches located at the front of the TOE (see Figure 1). These switches are joined by a bar in a manner that prevents both switches from being opened (i.e., no signal flow) or closed (i.e., signal flow) at the same time. 3. For the TOE, the following electronic isolation metric shall apply to ensure there is a minimum isolation between two sides of an open switch: • From 200 kHz to 300 kHz, the TOE shall show an attenuation greater than 78 dB. • From 300 kHz to 1.3 MHz, the TOE shall show an attenuation greater than 78 dB. • From 1.0 MHz to 11.0 MHz, the TOE shall show an attenuation greater than 79 dB. • From 10.0 MHz to 110.0 MHz, the TOE shall show an attenuation greater than 75 dB. Note: Quality RF coaxial switches normally are rated > 60 dB. 4. Assumptions and Clarification of Scope 4.1 Usage Assumptions The SecureSwitch® Dual Network Switch, Model #5000600 is an all-hardware stand- alone TOE. The following assumptions were made during the evaluation of the TOE. • The TOE was assumed to be connected as follows: - to one computer and two separate networks using standard network connectors or 8 - to two separate computers and two separate networks using standard network connectors; • Connections to and from the TOE were assumed to involve shielded cabling to minimize emanations from the connections; • Users of the TOE were assumed to possess the necessary privileges to access the network connections managed by the TOE; • Users of the TOE were assumed to be non-hostile; • Users of the TOE were assumed to follow all guidance. 4.2 Environmental Assumptions The following environmental assumption was made during the evaluation of the SecureSwitch® Dual Network Switch, Model #5000600 TOE. • The TOE was assumed to be located within controlled access facilities to prevent unauthorized physical access. 4.3 Clarification of Scope The SecureSwitch® Dual Network Switch, Model #5000600 was evaluated as a stand- alone TOE. In practice, however, it is realistic to assume that a purchaser of the TOE will use the product as a component of a system (e.g., consisting of a PC supporting an operating system and application software; a monitor; a keyboard; a mouse; network interface cards; shielded cables; and the TOE). Although the TOE has been evaluated at EAL4, it cannot be assumed that such a system provides EAL4 assurance. 5. Architectural Information The all-hardware SecureSwitch® Dual Network Switch, Model #5000600 TOE is comprised of three layers, identified as follows: • The two independent switch mechanisms (see Figure 1, Figure 4, and Figure 5); • The electronic interface connectors (see Figure 3); • The copper/iron shielded casing (see Figure 4 and Figure 5). Figure 1 and Figure 2 show the front and rear view, respectively, of the TOE. As can be seen in Figure 1, each of the two switch interfaces has a knob attached. The two knobs are connected by a crossbar, enabling both of them to switch at the same time. The crossbar is the only connection between the two switching mechanisms. Figure 3 contains an image of the left Ethernet PC board assembly (there are two per TOE, one left and one right). 9 Figure 3. Left Ethernet PC board assembly. Each Ethernet PC board assembly is placed into a proprietary copper/iron shielded casing as shown in Figure 4. Figure 4. Shielded tubes, each containing an Ethernet PC board assembly. Figure 5 shows the two shielded tubes, each containing an Ethernet PC board assembly, in position within the TOE prior to placement of the upper external protective casing. 10 Figure 5. Shielded tubes, each containing an Ethernet PC board assembly, in position within the TOE. The fully-assembled SecureSwitch® Dual Network Switch, Model #5000600 TOE (Figure 1 and Figure 2) contains no electrical connections between the two independent switch mechanisms. 6.
