Attack surface
The set of possible ways in for an attacker: exposed services, accounts, devices, and even people.
The attack surface is everything through which a hacker can try to get in: sites and services exposed on the Internet, accounts, devices, but also people via manipulation. The larger and less well understood it is, the greater the risk of a flaw being found. Reducing it, by disabling what is unnecessary and keeping an up-to-date inventory, is one of the most effective measures.
