Ja'far Alqatawna presented on applying data mining in security. He discussed trends showing that while encryption and defenses have advanced, security incidents are increasing. Factors contributing to insecurity include new technologies, connectivity, extensibility, and complexity. Data mining can help by analyzing large security data through classification, clustering, prediction, and correlation. Alqatawna discussed applying data mining for behavioral biometrics authentication, malicious spam detection, cybercrime detection, and adaptive security. He outlined two ongoing research projects on malicious spam detection in educational email systems and on social networks.
