Secure 5G Configuration

Secure 5G Configuration Training by Tonex

Misconfigured interfaces, excessive administrative privileges, and undocumented changes can undermine otherwise sound fifth-generation (5G) network designs. Secure 5G Configuration Training by Tonex develops a structured approach to defining, reviewing, and maintaining secure settings across network functions, radio access components, and supporting cloud environments. Participants examine configuration baselines, access restrictions, service exposure, encryption settings, logging, and controlled updates. The course emphasizes how to verify intended outcomes, distinguish operator policy from vendor defaults, and preserve records needed to investigate unexpected service behavior or configuration drift.

Disciplined configuration practices improve cybersecurity by reducing exploitable exposure and unauthorized changes. Continuous drift monitoring and accountable approvals strengthen cybersecurity resilience across operational network environments.

The course follows a practical training approach that includes exercises, real-world case studies, and examples of processes and documentation used in secure 5g configuration projects.

Course Modules

Module 1: Secure Configuration Baseline Principles

• Define approved configuration states for critical mobile network components
• Separate mandatory security controls from site-specific operational choices
• Review vendor defaults for unnecessary interfaces and permissive settings
• Document required protocols and restricted management communication paths
• Assign ownership for maintaining baseline templates and security exceptions
• Establish traceability from requirements to implemented configuration values

Module 2: Core Function Security Settings

• Review service exposure settings and permitted network function interactions
• Validate authentication and service authorization policy configuration assumptions
• Restrict unnecessary signaling endpoints and service discovery permissions
• Verify protection settings for administrative and service communication channels
• Identify weaknesses in subscriber and session policy administration
• Record function-specific deviations from approved network security baselines

Module 3: Access and Credential Configuration

• Enforce least privilege for network and platform administration accounts
• Define controlled procedures for issuing and revoking administrative credentials
• Review certificate lifetimes, trust anchors, and renewal responsibilities
• Separate emergency access from routine operational management permissions
• Disable dormant accounts and unnecessary remote management capabilities
• Establish periodic evidence of account and credential configuration reviews

Module 4: Hosting and Interface Hardening

• Review isolation between network functions and shared hosting services
• Limit platform service accounts and container runtime permissions
• Configure restricted traffic paths for management and network workloads
• Specify logging settings for privileged operations and service access
• Protect sensitive configuration records and deployment secrets against disclosure
• Assess interface security requirements for external enterprise and supplier connections

Module 5: Configuration Changes and Drift Detection

• Define approval gates for high-impact security configuration modifications
• Compare running settings against documented and versioned reference baselines
• Distinguish expected maintenance changes from unapproved configuration drift
• Verify integrity and provenance of configuration deployment artifacts
• Document corrective actions and rollback criteria for unsafe changes
• Review change effects across dependent network services and tenants

Module 6: Audit Readiness and Recovery Controls

• Establish secure backups of essential network and platform configurations
• Control restoration access and protect stored configuration secrets
• Collect evidence of baseline compliance and authorized deviations
• Summarize configuration weaknesses according to operational business risk
• Verify completion of corrective actions through recorded review evidence
• Maintain periodic baseline refresh and configuration governance schedules
