Layer 2 Security

This course provides a detailed understanding of network security technologies used to protect switching environments from common Layer 2 attacks and security threats. It explains how attackers can target the switching layer and how organizations can use built-in security features to reduce these risks. Throughout the course, learners will explore important Layer 2 protection tools and features, including DHCP Snooping, Dynamic ARP Inspection, Port Security, Private VLANs, and other switching security mechanisms. The course is designed to help learners understand how these features work, how they are applied in real network environments, and how they help strengthen the overall security of enterprise switching infrastructure.
