Why These Skills Matter?

 

Protecting Mission-Critical 5G Infrastructure: CNFs carry essential network functions such as UPF, AMF, and SMF. A misconfigured Kubernetes cluster can create vulnerabilities, leading to service outages or unauthorized access.

• Ensuring Network Resilience and Availability: Kubernetes skills enable operators to manage pods, nodes, and clusters efficiently. This ensures high availability, rapid recovery, and continuity of 5G services even under attack or failure conditions.

• Securing Containerized Workloads: Containers can be ephemeral and distributed, increasing the attack surface. Knowledge of RBAC, network policies, secrets management, and service mesh security is essential to safeguard CNFs.

• Compliance and Audit Readiness: Telco networks are subject to strict regulatory and cybersecurity standards. Kubernetes administration and monitoring skills ensure configurations are auditable, compliant, and defensible.

 

Entry requirements

• At least 3 years of cyber security experience

• Min. 1 year of work experience in telecommunication

• Been through T1-1 and T1-2 course in CyberXCenter, knowing the basic fundamentals of Telecommunication network

 

 

These skills empower telecom professionals to build, operate, and secure next-generation 5G networks, balancing innovation, performance, and cybersecurity. Without them, networks are vulnerable to service disruptions, cyberattacks, and regulatory penalties.

 

 

COURSE DURATION:

• 3 days of Instructor-led training

 

 

 

EXPECTATION AFTER THE TRAINING:

​

• Securely Deploy and Manage Kubernetes Clusters: Confidently set up, configure, and administer Kubernetes clusters tailored for 5G CNFs and implement RBAC, secrets management, and network policies to reduce attack surfaces.

• Operate and Monitor 5G CNFs Effectively: Deploy containerized network functions (CNFs) with proper scaling, high availability, and fault tolerance and use monitoring and logging tools (Prometheus, Grafana, ELK) to detect performance issues or security anomalies.

• Automate and Streamline Operations with Security: Integrate CI/CD pipelines and GitOps practices for safe, automated deployment of CNFs and perform updates, rollbacks, and patching without compromising cluster security.

• Troubleshoot and Respond to Security Incidents : Identify and resolve pod, node, and network issues quickly and apply best practices for incident detection and mitigation in Kubernetes-based 5G networks.
