1. Introduction: Attack Surface Management Challenges in the Digital Age
1.1 Evolution Background of Attack Surface Management
Today in 2025, enterprises face unprecedented cybersecurity challenges. As digital transformation deepens, large enterprises must manage a rapidly growing number of digital assets, including cloud services, API interfaces, web applications, mobile applications, IoT devices, and third-party integrations. These assets are distributed across multi-cloud environments, edge computing nodes, and traditional data centers, forming a highly complex and dynamic attack surface.
Traditional cybersecurity methods primarily focus on protecting known assets, while modern attackers often start with forgotten "shadow IT," misconfigured cloud services, or outdated third-party components. Many data breaches originate from shadow IT assets that are not effectively identified and managed by enterprise security teams. This "unknown unknown" becomes the biggest blind spot in enterprise security protection.
1.2 Paradigm Shift Brought by AI Technology
