What do you call the scope that hacker can use to break into a system?

The scope that a hacker can use to break into a system is often referred to as an "attack surface." This includes all potential points of entry, such as software vulnerabilities, network interfaces, and user access points. By identifying and exploiting weaknesses in this attack surface, hackers can gain unauthorized access to a system. Effective security measures aim to reduce the attack surface to minimize potential vulnerabilities.
