What Is an Attack Surface?
An attack surface consists of every point where an unauthorized person could attempt to enter a system, manipulate its operation, or extract information. Certification questions may describe a growing environment and ask which action most effectively reduces its attack surface. Accounts, endpoints, applications, open ports, cloud services, programming interfaces, remote-access tools, vendors, and employees can all create possible paths of attack. Installing unnecessary software or leaving inactive accounts enabled expands the attack surface even when those resources are not actively used. Organizations reduce exposure by removing unneeded services, closing ports, limiting privileges, consolidating systems, reviewing vendors, patching assets, and maintaining an accurate inventory of accessible resources.
