Answer:
metasploit.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Metasploit is a penetration testing tool that combines known scanning and exploit techniques to explore potentially new attack routes. It's officially and formally licensed to Rapid7, a company based in Boston, Massachusetts.
Basically, metasploit is a framework that's mainly focused on availing end users such as ethical hackers, with information about security vulnerabilities in a system, development of intrusion detection system (IDS) signature and modular penetration testing.
