Network security tools

Assuming familiarity with C, Perl, and the use of assessment tools, this guide introduces techniques for modifying open source assessment tools and testing security vulnerabilities in networks and web applications. The authors, who are managers at Ernst & Young's advanced security center, discuss Nessus, Ettercap, Hydra, Nikto, the Metasploit framework, the PMD tool, Linux kernel modules, network sniffers, and packet injectors.
