8. When undertaking a cloud migration of multiple SaaS applications, an organization's systems administrators struggled with the complexity of extending identity and access management to cloud-based assets. Which of the following service models would have reduced the complexity of this project?
Answer: C
ZTNA would have reduced the complexity of the cloud migration project.
Implementing Zero Trust Network Access (ZTNA) would have simplified the integration of identity and access management for cloud-based assets during the migration of multiple SaaS applications. This approach provides secure access to applications regardless of the user's location, streamlining the management of access controls.
A) RADIUS
RADIUS (Remote Authentication Dial-In User Service) is primarily focused on network access authentication and may not adequately address the complexities of managing access for multiple cloud applications. While it can facilitate secure user authentication, it does not provide the comprehensive access management and segmentation capabilities that ZTNA offers for cloud environments.
B) SDN
Software-Defined Networking (SDN) focuses on managing and optimizing network resources and traffic. While it can improve network management, SDN does not specifically address the challenges of identity and access management for cloud applications. Therefore, it would not effectively reduce the complexity faced by systems administrators during a cloud migration.
C) ZTNA
ZTNA provides a framework that enhances security by verifying user identity and context before granting access to applications. This model simplifies the administration of access controls across various SaaS applications, making it easier for organizations to manage and enforce security policies during a cloud migration.
D) SWG
Secure Web Gateway (SWG) is designed to protect users from online threats and enforce security policies for web traffic. However, it does not inherently simplify identity and access management for cloud-based applications as ZTNA does. As such, it would not provide the same level of support in reducing complexity during the migration process.
Conclusion
ZTNA is the most suitable service model for simplifying identity and access management during a cloud migration of multiple SaaS applications. Unlike RADIUS, SDN, or SWG, ZTNA streamlines access control and enhances security by ensuring that only verified users can access specific applications, thereby effectively addressing the complexities faced by systems administrators in this scenario.
