Abstract

Traversing through multiple pages of log entries, trying to detect malicious and anomalous behavior and being able to correlate events to address multiple use cases is a non trivial task for a security administrator. It requires resources, expert knowledge and time. In this paper, we present a novel security visualization system entitled Avisa. It accentuates fundamental matters of information visualization, namely interaction and animation and synthesizes it with intrusion detection audit traces. Visual constraints inspired the use of heuristic metrics to select and display hosts with irregular and variant behaviors. We thoroughly describe the ideas behind the heuristic metrics and perform an empirical analysis to individually evaluate each metric's functionality. Avisa's intuitive interface, accompanied by the power of the heuristic functions, allows the perception of patterns and emergent properties, facilitating in understanding the underlying data.
