Exposure Management Guidebook for Security Practitioners

This guidebook serves as a comprehensive resource for security practitioners seeking to implement exposure management (EM) within their organizations. It outlines the significance of EM in proactively identifying and managing attack surface risks, emphasizing the need for automation and scalability to enhance efficiency. The document details the framework of continuous threat exposure management (CTEM), which includes five key steps: scoping, discovery, prioritization, validation, and mobilization. Each step is designed to improve an organization’s security posture by reducing vulnerabilities before they can be exploited. Additionally, the guidebook discusses the challenges posed by traditional vulnerability management approaches, highlighting the gaps in asset coverage and the need for a more integrated and automated workflow. It also provides practical steps for initiating an EM program, including recognizing the need for change and assembling a task force. Overall, the guidebook aims to equip security teams with the knowledge and tools necessary to effectively manage their external attack surfaces.
