Attack Surface Management (ASM) is the process of identifying, monitoring, and managing an organization's attack surface—the sum of all potential entry points that an attacker could exploit to gain unauthorized access to systems, networks, or data. The attack surface includes all assets, such as applications, servers, endpoints, cloud services, and network devices, that are exposed to the internet or accessible by users. ASM involves continuously discovering and assessing these assets to identify vulnerabilities, misconfigurations, and other security risks that could be exploited by attackers. By proactively managing the attack surface, organizations can reduce their exposure to cyber threats.
