Which software below combines known scanning techniques and exploits to allow for hybrid exploits?

a. sub7

b. metasploit

c. nmap

d. nessus?

The answer would be metasploit as it has tools for both scanning and exploiting a system. Sub7 is a program used only for creating trojan horse exploits, nmap uses scanning techniques to create a map of a network and nessus uses scans to detect vulnerabilities in a system. Metasploit is the only piece of software that has the functionality to do both.
