🎯 What is an Attack Surface?

Your Attack Surface is the sum of all entry points an attacker could target:

🌐 Digital: Open ports, exposed cloud assets & APIs.

👤 Human: Employees targeted by phishing.

Rule: Larger attack surface = Harder to defend.
Key Step: Reduce exposure by closing unused ports, patching regularly, and enforcing strict access controls.
