    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: In a method of generating an anomaly detection model for classifying activities of a computer system, using a training set of data corresponding to activity on the computer system, the training set comprising a plurality of instances of data having features, and wherein each feature in said plurality of features has a plurality of values. For a selected feature and a selected value of the selected feature, a quantity is determined which corresponds to the relative sparsity of such value. The quantity may correspond to the difference between the number occurrences of the selected value and the number of occurrences of the most frequently occurring value. These instances are classified as anomaly and added to the training set of normal data to generate a rule set or other detection model.

    摘要: The semantic integration problem for merging multiple databases of very large size, the merge/purge problem, can be solved by multiple runs of the sorted neighborhood method or the clustering method with small windows followed by the computation of the transitive closure over the results of each run. The sorted neighborhood method works well under this scheme but is computationally expensive due to the sorting phase. An alternative method based on data clustering that reduces the complexity to linear time making multiple runs followed by transitive closure feasible and efficient. A method is provided for identifying duplicate records in a database, each record having at least one field and a plurality of keys, including the steps of sorting the records according to a criteria applied to a first key; comparing a number of consecutive sorted records to each other, wherein the number is less than a number of records in said database and identifying a first group of duplicate records; storing the identity of the first group; sorting the records according to a criteria applied to a second key; comparing a number of consecutive sorted records to each other, wherein the number is less than a number of records in said database and identifying a second group of duplicate records; storing the identity of the second group; and subjecting the union of the first and second groups to transitive closure.
