The Exploit Database is a CVE compliant archive of public exploits and corresponding vulnerable software, developed for use by penetration testers and vulnerability researchers. NMAP and NSE has hundreds of commands you can use to scan an IP, but Ive chosen these commands for specific reasons; to increase verbosity, to enable OS and version detection, and to probe open ports for service information.
