    摘要: In one embodiment, the present invention is a method and apparatus for detecting malware infection. One embodiment of a method for detecting a malware infection at a local host in a network, includes monitoring communications between the local host and one or more entities external to the network, generating a dialog warning if the communications include a transaction indicative of a malware infection, declaring a malware infection if, within a predefined period of time, the dialog warnings includes at least one dialog warning indicating a transaction initiated at the local host and at least one dialog warning indicating an additional transaction indicative of a malware infection, and outputting an infection profile for the local host.

    摘要: In one embodiment, the present invention is a method and apparatus for generating highly predictive blacklists. One embodiment of a method for generating a blacklist of network addresses for a user of a network includes collecting security log data from users of the network, the security log data identifying observed attacks by attack sources, assigning the attack sources to the blacklist based on a combination of the relevance each attack source to the user and the maliciousness of the attack source, and outputting the blacklist.

    摘要: A method of network surveillance includes receiving network packets handled by a network entity and building at least one long-term and a least one short-term statistical profile from a measure of the network packets that monitors data transfers, errors, or network connections. A comparison of the statistical profiles is used to determine whether the difference between the statistical profiles indicates suspicious network activity.

    摘要: This invention uses Bayesian techniques to prioritize alerts or alert groups generated by intrusion detection systems and other information security devices, such as network analyzers, network monitors, firewalls, antivirus software, authentication services, host and application security services, etc. In a preferred embodiment, alerts are examined for the presence of one or more relevant features, such as the type of an attack, the target of an attack, the outcome of an attack, etc. At least a subset of the features is then provided to a real-time Bayes network, which assigns relevance scores to the received alerts or alert groups. In another embodiment, a network manager (a person) can disagree with the relevance score assigned by the Bayes network, and give an alert or alert group a different relevance score. The Bayes network is then modified so that similar future alerts or alert groups will be assigned a relevance score that more closely matches the score given by the network manager.
