As we become more dependent on data in every aspect of our lives the task of protecting it and applications dependant on it becomes harder. The sheer quantity of data and sophistication of the attacks is rapidly making manual analysis infeasible. Security Analytics will examine how we can protect data and automate the analysis of data to better detect, predict and prevent privacy and security vulnerabilities.
The subject will first introduce the types of information leakage that can occur under several threat models and explore methods for protecting sensitive content during data analysis. The second part of the subject will introduce methods from machine learning that are widely used for cyber security analysis. Specific unsupervised machine learning techniques will be covered in more detail, which include methods for anomaly detection, alarm correlation and intrusion detection. The third part of the subject will introduce some of the theoretical challenges and emerging issues for security analytics research, based on recent trends in the evolution of security threats.
Indicative examples of the emerging challenges and issues that will be studied are privacy‐preserving analytics, adversarial machine learning, concept drift and new applications in monitoring critical infrastructure.
