An attack surface is the sum of all the points where an attacker can try to enter or extract data from an environment. It includes all the hardware, software, network, and human components that are exposed to potential threats. An attack vector is the path or means by which an attacker can exploit a vulnerability in the attack surface. It describes the type, source, and technique of an attack, such as phishing, malware, denial-of-service, etc. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 1: Security Concepts, Lesson 1.1: The CIA Triad and Security Concepts, Topic 1.1.3: Threats, Vulnerabilities, and Exploits
