In INDIGO, ensuring the security of both orchestration and established 5G services is crucial. It’s also important for end-users to know the security level of the services they use. Key security considerations include:

• Assessing Security Levels: Using both direct (southbound API) and indirect (northbound API) information to evaluate the network’s security level.
• Intelligent Processing: Using AI and Machine Learning (ML) through the DoD security rApp to configure radio bearers and slices for DoD use.
• Responsive Security Measures: Reacting to triggers to change RAN settings to maintain secure operations, ensuring DoD-grade security with built-in auditable features.

For the Security rApp, INDIGO is considering NIST Zero-Trust capabilities. These capabilities could be implemented as third-party rApps that can be quickly onboarded, either from commercial partners or other Track G Phase 2 project teams.

This approach ensures robust security for the orchestration process and the 5G services provided, aligning with the stringent requirements of the Department of Defense and providing transparency to end-users regarding the security of their services.
