Attack Surface Management

Chapter 7. Measuring Attack Surface

In this chapter, we explore the process of measuring an organization’s attack surface, focusing on both internal and external aspects. We will explore how identity and access management are pivotal in securing these surfaces and introduce essential techniques like threat modeling and attack surface mapping. These methods are crucial for assessing and enhancing the security framework, providing a comprehensive overview and actionable insights into protecting an organization’s digital and physical assets against potential threats.

Attack Surface Analysis

Attack surface analysis (ASA) is an essential practice in ASM that identifies, classifies, and prioritizes vulnerabilities across an organization’s digital and physical assets. By defining and understanding the scope of potential risks within networks, applications, and systems, ASA serves as a crucial tool for ensuring robust security measures are in place. This comprehensive visibility is pivotal for organizations to safeguard their infrastructure against various threats.

The significance of ASA extends beyond mere identification; it is foundational in shaping an organization’s security strategies. By providing a clear map of vulnerabilities, ASA enables security teams to effectively develop targeted measures and policies that address specific weaknesses. That approach improves the security of sensitive assets and supports the broader objectives of risk management.
