Massive distributed and parallel log analysis for organizational security

Security log analysis is extremely useful for uncovering intrusions and anomalies. However, the sheer volume of log data demands new frameworks and techniques of computing and security. We present a lightweight distributed and parallel security log analysis framework that allows organizations to analyze a massive number of system, network, and transaction logs efficiently and scalably. Different from the general distributed frameworks, e.g., MapReduce, our framework is specifically designed for security log analysis. It features a minimum set of necessary properties, such as dynamic task scheduling for streaming logs. For prototyping, we implement our framework in Amazon cloud environments (EC2 and S3) with a basic analysis application. Our evaluation demonstrates the effectiveness of our design and shows the potential of our cloud-based distributed framework in large-scale log analysis scenarios.
