| Abstract: | A monitoring device for monitoring transactions on a bus includes
content-addressable memory ("CAM") and a response policy unit. The CAM
includes an input coupled to receive a bus transaction tag based on bus
traffic on the bus. The CAM stores data tags associated with rules of a
security policy to compare the bus transaction tag to the data tags. The
CAM generates an output signal indicating whether one or more matches
occurred. The response policy unit is coupled to the CAM to receive the
output signal from the CAM and to execute a policy action in response to
the output signal. |
