The devices in question include the following. Shore Micro SM-2400 Programmable Bypass Switch: This device has TX copper connectors and may support Gigabit Ethernet. Optical Bypass Switch with Heartbeat: This device has SX fiber connectors and supports Gigabit Ethernet. 10/100/1000 Bypass Switch with Heartbeat: This device has TX copper connectors and supports Gigabit Ethernet. Interface Masters Niagara 2295RJ: This device has TX copper connectors and supports Gigabit Ethernet. I find it interesting that it does not require a power supply, but I wonder how it supports a heartbeat without power? Niagara 2282: This is an internal NIC that acts as a bypass switch. It has SX fiber connectors and supports Gigabit Ethernet. Niagara 2280: This is an internal NIC that acts as a bypass switch. It has SX fiber connectors and supports Gigabit Ethernet. I don't see functional differences between this NIC and the previous, but that is a preliminary assessment. So those are the devices. This is how I intend to deploy them for testing.
traffic generator transmitter NIC
bypass switch inbound NIC
bypass switch monitor NIC 1 --> sensor NIC 1
bypass switch monitor NIC 2 --> sensor NIC 2
bypass switch outbound NIC
traffic generator receiver NIC
For the internal devices, I will have the internal NIC in the sensor feeding a second NIC in the same sensor.
At the moment my main goals are to fully understand how each device works, feature-wise. I plan to do some limited testing this week with the equipment on hand. Next week I plan to use commercial load generators to stress the devices.
Let me know as a comment on TaoSecurity Blog or email to richard [at] taosecurity.com if you have ideas regarding what I should do with these systems.
