5G API Security

5G API Security Training by Tonex

Fifth Generation (5G) systems depend on Application Programming Interfaces (APIs) for interactions between core network functions and for controlled exposure of mobile capabilities to business partners. 5G API Security Training by Tonex develops a practical understanding of service-based communication, network exposure, identity verification, and fine-grained authorization. Participants review access tokens, client identities, gateway policy, data minimization, and the operational consequences of excessive permissions. The course distinguishes internal core interfaces from external developer-facing interfaces and explains how trust, consent, and traffic controls should reflect the sensitivity of each service.

Strong interface controls improve cybersecurity by restricting unauthorized requests and sensitive data disclosure. Effective monitoring strengthens cybersecurity resilience by detecting suspicious token use, service abuse, and unsafe integration changes.

A practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in 5g api security projects.

Learning Objectives

• Distinguish internal 5G service interfaces from externally exposed network capability APIs.
• Explain authentication, authorization, and client trust in mobile service integrations.
• Assess token scopes, consent obligations, and personal data access boundaries.
• Specify gateway protections for rate limiting, input validation, and service resilience.
• Identify abuse scenarios involving exposed functions and third-party API consumers.
• Develop monitoring, incident response, and interface change governance requirements.
• Enhance cybersecurity by enforcing least privilege and auditable API access.

Course Modules

Module 1: 5G Service Interface Fundamentals

• Explain service-based communication between mobile core network functions
• Identify protected internal interfaces and externally exposed service capabilities
• Describe the role of the Network Exposure Function in controlled access
• Map application clients, network providers, and service trust boundaries
• Document sensitive information flows and interface ownership assignments
• Assess how exposed endpoints increase operational and cybersecurity dependencies

Module 2: API Authentication and Authorization

• Distinguish client authentication from permission to use particular services
• Examine Open Authorization (OAuth) 2.0 access token usage principles
• Review token scope, audience, expiration, and issuer validation requirements
• Define service permission boundaries for internal and external clients
• Assess secure credential storage and rotation responsibilities across integrations
• Document certificate trust and protected communication requirements for endpoints

Module 3: Consent Privacy and Data Protection

• Identify network API operations that may involve personal information
• Separate service authorization from valid subscriber consent where applicable
• Define data minimization requirements for returned location and identity attributes
• Assess privacy risks in application event notifications and callbacks
• Specify retention and access controls for sensitive request records
• Document consent evidence and privacy responsibilities across service partners

Module 4: Gateway Controls and Abuse Prevention

• Design consistent gateway policies for exposed mobile network services
• Apply request validation and clear service schema enforcement requirements
• Define rate limits and quotas appropriate to service sensitivity
• Assess risks from replay attempts and unauthorized parameter manipulation
• Review protection against resource exhaustion and abnormal request patterns
• Record exceptions for legacy clients and necessary compensating safeguards

Module 5: API Threat Detection and Incidents

• Identify event records needed for request attribution and investigation
• Correlate token usage, client identities, response codes, and service activity
• Detect anomalous consumption patterns and unexpected access to restricted capabilities
• Define suspicious client suspension and credential revocation procedures
• Coordinate incident communications with partners and network service owners
• Preserve investigation evidence while respecting applicable privacy safeguards

Module 6: API Security Assurance and Governance

• Establish secure onboarding requirements for third-party network API consumers
