Latest Patents

Fitzgerald's latest patents include a groundbreaking system for network intrusion detection with distributed correlation. This network security system employs multiple levels of processing to identify security threats. Multiple host machines may each contain an agent that detects possibilities of security threats based on raw data sensed locally at that host. The hosts may share information obtained from local analysis, and each host may use information generated at one or more other hosts, in combination with information generated locally, to identify a security concern, indicating with greater certainty that a security threat exists. Based on security concerns generated by multiple hosts, a security threat may be indicated, and protective action may be taken.

Another significant patent involves the analysis of computer network activity by successively removing accepted types of access events. This analysis system is designed to identify potentially malicious activity within a computer network. It performs this task by interacting with a user to successively remove known instances of non-malicious activity, ultimately revealing potentially malicious activity. The analysis system interacts with the user by inviting them to apply labels to identified examples of network behavior. Upon response by the user, the analysis system supplies new examples of network behavior to the user. In one implementation, the analysis system generates such examples using a combination of feature-based analysis and graph-based analysis. The graph-based analysis relies on the analysis of graph structure associated with access events, such as by identifying entropy scores for respective portions of the graph structure.
