Cisco IINS 3.0: Cisco IOS Zone Based Firewall
This course is directed towards networking professionals who need to understand common security concepts and deploy basic security techniques using a variety of popular security solutions including IOS routers, IOS switches, Cisco Adaptive Security Appliances and Windows and Linux hosts. This course is also designed for security practitioners who want to pass the IINS 3.0 exam.
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.
