What is an Attack Surface?

An attack surface refers to all the possible points where an unauthorized user or malicious actor could attempt to access a system or network. These entry points can range from publicly accessible assets (like domains, servers, APIs) to hidden misconfigurations or gaps within an organization's security infrastructure.

Attack surfaces are generally categorized into two types: physical and digital.

  • Physical attack surfaces include devices and infrastructure (e.g., workstations, servers, network hardware) that an attacker could physically access. These are often easier to secure by implementing access control policies and physical security best practices.
  • Digital attack surfaces, on the other hand, are more complex and constantly evolving. They include internet-facing assets, cloud services, subdomains, APIs, credentials leaks, third-party dependencies, and more. Managing digital attack surfaces requires continuous discovery and monitoring—especially as organizations grow and adopt new technologies.

The size and complexity of an organization's attack surface depends on its digital footprint, which may include both known and unknown assets. This makes proactive visibility and management critical.
