Intrusion Detection Systems (IDS) have been widely deployed in practice for detecting malicious behavior on network communication and hosts. The problem of false-positive alerts is a popular existing problem for most of IDS approaches. The solution to address this problem is correlation and clustering of alerts. To meet the practical requirements, this process needs to be finished as fast as possible, which is a challenging task as the amount of alerts produced in large scale deployments of distributed IDS is significantly high, due to the deployment of IDS sensors in cloud computing and open network designs (e.g., SOA).
