The traditional IDS can not effectively manage the new continuously changing intrusion detection attacks. To deal with the problem, data mining based intrusion detection methods have been the hot fields in intrusion detection research. An outlier mining based adaptive intrusion detection framework is proposed in this paper. In the proposed framework, the outliers are firstly detected by similarity...
Given a program and an attack pattern (specified as a regular expression), we automatically generate string-based vulnerability signatures, i.e., a characterization that includes all malicious inputs that can be used to generate attacks. We use an automata-based string analysis framework. Using forward reachability analysis we compute an over-approximation of all possible values that string variables...
Along with increasing credit cards and growing trade volume in China, credit card fraud rises sharply. How to enhance the detection and prevention of credit card fraud becomes the focus of risk control of banks. This paper proposes a credit card fraud detection model using outlier detection based on distance sum according to the infrequency and unconventionality of fraud in credit card transaction...
