Résumé du cours
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 CGNAT, DDoS, malware inspection, command-and-control prevention, IPsec tunnels, 5G security, control plane hardening, and BGP hardening. Students will gain experience in configuring, testing, and troubleshooting the Junos OS through demonstrations and hands-on labs. This course is based on Junos OS 21.1R1.11.
