An attack surface is the full set of points where an unauthorized user could try to enter or extract data from a system. It includes every exposed endpoint, API, port, service, credential, and human path an attacker might target. Reducing the attack surface means eliminating unnecessary exposure to lower risk.
Attack surface grows quietly: a forgotten subdomain, an exposed admin panel, a stale API key, a third-party integration. Attackers inventory these continuously, so defenders need to as well.
Attack surface management is the ongoing discipline of discovering, monitoring, and shrinking that exposure. The fastest risk reduction is usually removing things you no longer need rather than adding new defenses.
