A network is a collection of many devices, where each node is said to be wired or wireless connection between them. And now a day's most of the threat comes to the network either from outside or from a sort of situation which occurs internally due to many reasons. So the Intrusions or threat which occurs due to these situations are generally more damageable than the normal ones. This paper is introducing a technique to analyze various types of alerts & also generating attack graph for such alerts by using two algorithm i.e. correlation of isolated alerts to alert-pair, attack graph generation. And after analyzing the threat the authors are also performing evaluation technique to determine the seriousness of the threat and remove it.
