Abstract
A detection and response system that generates an Alert if unauthorized scanning is detected on a computer network that includes a look-up table to record state value corresponding to the sequence in which SYN, SYN/ACK and RST packets are observed. A set of algorithms executed on a processing engine adjusts the state value in response to observing the packets. When the state value reaches a predetermined value indicating that all three packets have been seen, the algorithm generates an Alert.
