Security mechanisms within DBMSs are far from effective to detect and prevent anomalous behavior of applications and intrusions from attackers. In fact, intrusions executed by unauthorized users to explore system vulnerabilities, and malicious database transactions executed by authorized users, both cannot be detected and prevented by typical security mechanisms. In this paper we proposed a database...
Dissemination control is concerned with controlling electronic resources even after they have been delivered to a legitimate recipient. This paper proposes a secure resource dissemination system framework in which resource providers and recipients are interacted mutually in an anonymous, accountable, and trustworthy way, while security constraints on diverse resources can be continuously protected...
This paper presents a new approach to detect attacks from network activities. Network connections were transformed into data points in the predefined feature space. The influence function was designed to quantify the influence of an object and, further, the data field was divided into positive field and negative field according to the source point's category. To perform classification, all the labeled...

In this paper, we propose a method to find the anomalous behaviors in network traffic. We map the network connection records into different feature spaces typically of high dimension according to their protocols and services. In training, we perform clustering to group training data points into clusters, from which we select some clusters as normal and known-attack profile according to a simple, but...
