Agent based system for network availability and vulnerability monitoring

Monitoring of distributed systems for management purposes is a complex task aggravated by heterogeneity and distribution of resources and tools. This paper describes implementation of the agent-based system for network (Internet) services monitoring. The system is designed in a modular fashion to provide easy and efficient inclusion of diverse network services' monitoring components. Software agents are implemented aimed at verification of accessibility of network services, as well as their potential vulnerability. Specialized services and verifiers for the web and e-mail services are also implemented. The system implementation is based on the XJAF agent framework and the Java EE technology.
