Attack Surface Management (ASM) is a security procedure that aims to minimize the likelihood of an attack on an organization's information systems. All system entry points, such as network interfaces, programs, services, and user accounts, must be systematically identified and evaluated. ASM aims to reduce a system's attack surface, making it more challenging for attackers to exploit flaws and gain unauthorized access.

ASM employs several strategies and instruments to locate and evaluate potential attack vectors, including threat modeling, penetration testing, and security evaluations. These evaluations inform the prioritization of mitigation efforts to enhance the organization's security posture.

ASM is a continuous process that involves monitoring and updating the attack surface to lower the organization's total risk by ensuring that security vulnerabilities are found and fixed quickly.

Organizations may improve their overall security posture, reduce the potential effect of a successful assault, and make it harder for attackers to access their systems by decreasing the attack surface.
