Attack Surface

An attack surface is the sum of an organization’s attacker-exposed IT assets, whether these assets are secure or vulnerable, known or unknown, in active use or not and regardless of IT/security team is aware of them.

The attack surface changes continuously over time, and includes assets that are on-premises, in the cloud, and in subsidiary networks as well as those in third-party or partner environments.
