Which of the following is the MAIN purpose of system hardening?

System hardening is a process that involves implementing security measures to reduce the system’s vulnerability. The main purpose of this process is to limit the number of attack vectors that can be exploited by threats. By removing unnecessary programs, closing unused ports, and applying security patches, the system’s attack surface is reduced, making it more difficult for attackers to find vulnerabilities to exploit.

References: The concept of system hardening is covered in ISACA’s resources as a means to protect information assets by addressing threats to information processed, stored, and transported by internetworked information systems1. It is a collection of tools and techniques aimed at reducing vulnerability in various areas of an IT system2.
