Executive Summary

Due to the people increasing reliance on computer systems, security incidents and their causes are important problems that need to be addressed. To contribute to this objective, the paper describes a new tool for the discovery of security vulnerabilities on network connected servers. The AJECT tool uses a specification of the server's communication protocol to automatically generate a large number of attacks accordingly to some predefined test classes. Then, while it performs these attacks through the network, it monitors the behavior of the server both from a client perspective and inside the target machine. The observation of an incorrect behavior indicates a successful attack and the potential existence of vulnerability.
