Determining optimal Sensor location

Instead, consider the configuration in Figure “Stack” configuration for a single path:

Figure 3: Stack Configuration

In this scenario, the Sensors are “stacked” (one after the other) in much the same way you

might daisy chain a pair of switches.

Note: A crossover cable is required to make the connection between the Sensor

monitoring ports.

These Sensors are configured to run inline, failopen, and function as a failover Pair.

The advantages of this redundant configuration over others on a network with a single

path are as follows:

• There is no dependency on the Layer 2 or Layer 3 topologies for Sensor redundancy.

• If one Sensor fails, it fails open, and the other Sensor continues to scan with no

interruption.

• Because they are configured as a failover Pair, state will be maintained.

The single disadvantage is that duplicate alerts will be generated for UDP and ICMP

attacks. (More on this later in this document.)
