This three-day course discusses edge security concepts for the service provider network. It discusses security for 5G networks on the main GPRS interfaces. Key topics include deploying an SRX Series device in different parts of the service provider network, implementing carrier-grade NAT, distributed denial of service (DDoS), malware inspection, command-and-control (C&C) prevention, IPsec tunnels, 5G security, control plane hardening, and BGP hardening. Additional topics include deploying MX-SPC3 card, configuring and verifying IPsec VPNs, and carrier-grade NAT, with unified services framework on MX Series platforms.

Students will gain experience in configuring, testing, and troubleshooting Junos OS through demonstrations and hands-on labs. This course is based on Junos OS 21.1R1.11.

• Define the general security architecture for 4G and 5G networks.
