What is an internal attack surface?

Internal attack surface consists of all cyber assets within an organization's internal environment, including its networks, systems, and resources. 

How does it differ from the external attack surface?

The external attack surface involves protecting an organization’s perimeter from outside threats, while the internal attack surface focuses on assets and vulnerabilities that could be exploited inside the network, often by attackers who have already bypassed external defenses or by internal actors.

How do you identify and map your organization's internal attack surface?

To identify and map your organization’s internal attack surface, start by creating a comprehensive inventory of all internal assets, prioritize them based on criticality, and identify any vulnerabilities. Assess access paths and permissions to understand potential risk areas. For continuous discovery, monitoring, and analysis, leverage a Cyber Asset Attack Surface Management (CAASM) solution to ensure real-time visibility and control over your internal assets.
