For years, security was focused primarily on Layer 3 of the OSI model with Layer 2 getting less attention. This ‘house of cards’ scenario must be prevented in today’s modern networks. The data link layer 2 of the OSI model, provides MAC address based connectivity within a broadcast domain, such as an Ethernet LAN. Network technologies are implemented in stacks, broken into layers. This layer can be protected with a wide array of techniques for securing VLANs and 802.1Q trunks. Various solutions like ACLs, VACLs, and PACLs are explored as well.
