摘要： Methods, media, and systems for detecting an anomalous sequence of function calls are provided. The methods can include compressing a sequence of function calls made by the execution of a program using a compression model; and determining the presence of an anomalous sequence of function calls in the sequence of function calls based on the extent to which the sequence of function calls is compressed. The methods can further include executing at least one known program; observing at least one sequence of function calls made by the execution of the at least one known program; assigning each type of function call in the at least one sequence of function calls made by the at least one known program a unique identifier; and creating at least part of the compression model by recording at least one sequence of unique identifiers.

摘要： Systems, methods, and media for detecting network anomalies are provided. In some embodiments, a training dataset of communication protocol messages having argument strings is received. The content and structure associated with each of the argument strings is determined and a probabilistic model is trained using the determined content and structure of each of the argument strings. A communication protocol message having an argument string that is transmitted from a first processor to a second processor across a computer network is received. The received communication protocol message is compared to the probabilistic model and then it is determined whether the communication protocol message is anomalous.

摘要： Systems and methods provide an alert correlator and an alert distributor that enable early signs of an attack to be detected and rapidly disseminated to collaborating systems. The alert correlator utilizes data structures to correlate alert detections and provide a mechanism through which threat information can be revealed to other collaborating systems. The alert distributor uses an efficient technique to group collaborating systems and then pass data between certain members of those groups according to a schedule. In this way data can be routinely distributed without generating excess traffic loads.

摘要： In accordance with some embodiments, systems and methods that protect an application from attacks are provided. In some embodiments, traffic from a communication network is received by an anomaly detection component. The anomaly detection component monitors the received traffic and routes the traffic either to the protected application or to a honeypot, where the honeypot shares all state information with the application. If the received traffic is routed to the honeypot, the honeypot monitors the traffic for an attack. If an attack occurs, the honeypot repairs the protected application (e.g., discarding any state changes incurred from the attack, reverting to previously saved state information, etc.).
