It outlines the challenges posed by the expanding digital perimeter, emphasizing that organizations frequently underestimate their attack surfaces. Key issues include shadow IT, legacy infrastructure, orphaned assets, third-party connections, and cloud sprawl. The paper presents real-world consequences of security breaches, such as the Change Healthcare incident, which highlighted the risks associated with insufficient subsidiary security. Additionally, it addresses operational challenges, regulatory complexities, and inconsistent security standards that arise in multi-entity organizations.
