Scanning for vulnerabilities is the first step for both securing and attacking a network. In this video, Chad Russell demonstrates how OpenVAS can be used to scan your network for hosts and fingerprint their listening services to obtain access. All that is needed to follow along is access to a Linux operating system and a basic knowledge of the command line. System administrators and security engineers will be able to use this information proactively to patch and secure their networks before attackers exploit weaknesses.
