What is attack surface management?
Attack Surface Management (ASM) is a cybersecurity strategy aiming to identify, assess, and secure all external digital assets accessible from the internet. In a world where digital footprints expand daily, ASM monitors and mitigates the risks associated with these evolving attack vectors. By continuously identifying exposed data, unsecured servers, misconfigured cloud services, and other vulnerabilities, it minimizes the ‘surface’ that attackers can exploit. ASM solutions also help organizations adhere to security compliance regulations. This proactive approach is crucial in today’s digital landscape to safeguard the integrity, confidentiality, and availability of an organization’s information systems. Remember, in cybersecurity, your defenses are only as strong as your weakest point; ASM ensures there are as few weak points as possible.

Finding your new attack surface management software
Understanding the Components of an Attack Surface
Physical components
Physical components include any hardware that can be physically accessed or manipulated to gain unauthorized entry into a system. This includes servers, laptops, smartphones, routers, and IoT devices. Ensuring physical security is a fundamental part of ASM.
Digital components
Digital components of an attack surface are the software or digital systems, including operating systems, applications, databases, and networks, that can be exploited. A large digital attack surface may pose a higher risk due to the potential for software bugs, misconfigurations, and unpatched vulnerabilities.
Human components
Humans represent the third pillar of an attack surface. This includes employees, contractors, or any individual with access to your systems. Human error, negligence, or malicious intent can introduce serious vulnerabilities, making education and awareness key elements in managing this aspect of the attack surface.

Key challenges in attack surface management
Growing complexity of networks
As businesses adopt new technologies, their attack surfaces expand and become more complex. This includes a rise in the use of cloud services, IoT devices, and mobile technologies, which can create additional entry points for attackers.
Rapidly evolving threat landscape
Cyber threats are constantly evolving, with new vulnerabilities and attack vectors emerging regularly. This makes the task of managing and securing an organization’s attack surface an ongoing challenge.
Managing unknown assets
A significant challenge in ASM is the management of unknown or unmanaged assets. These can range from forgotten servers to third-party applications, which often slip under the radar and provide potential footholds for attackers.
Best practices for effective attack surface management
Regular asset discovery and management
Continuous identification and tracking of assets is crucial for effective ASM. Regular inventory checks, network mapping, and automated discovery tools can help keep track of all components in your attack surface.
Continuous vulnerability assessments
Regularly scanning for vulnerabilities helps identify weaknesses that could be exploited by attackers. Employing continuous vulnerability assessment tools provides a more proactive and dynamic approach to threat management.
Prioritization of remediation efforts
Not all vulnerabilities pose the same risk. Prioritizing remediation efforts based on the potential impact and ease of exploitability of vulnerabilities helps optimize resource allocation and reduce risk faster.
Employee training and awareness
People are often the weakest link in security. Regular cybersecurity training and awareness programs can significantly reduce the risk of human-induced security incidents and enhance your overall security posture.
