Abstract

Runtime verification permits checking system properties that cannot be fully verified off-line. This is particularly true when the system includes complex third-party components, such as general-purpose operating systems and software libraries, and when the properties of interest include security and performance. The challenge is to find reliable ways to monitor these properties in realistic systems. In particular, it is important to have assurance that violations will be reported when they actually occur. For instance, a monitor may not detect a security violation if the violation results from a series of system events that are not in its model.

We describe how combining runtime monitors for diverse features such as memory management, security-related events, performance data, and higher-level temporal properties can result in more effective runtime verification. After discussing some basic notions for combining and relating monitors, we illustrate their application in an intrusion-tolerant Web server architecture under development at SRI.
