As the network engineer for your company you are responsible for all network-related tasks. One day your security officer comes to you and asks is you can further enhance the network security. He wants you to implement an IOS Firewall feature to protect incoming traffic

One of the issues facing network and security engineers is defending the network against dynamic threats. This means traffic that cannot easily be identified by regular means, such as an application that changes layer 4 ports or tunnels within an existing protocol. Because of this, a solution is needed to match and filter based on specific information within the packet that is unique to the application you want to block.

In the previous installment of our series of IPv6 security posts, we covered some of the ways addressing has changed in IPv6 compared to IPv4. In this post, we'll talk about some of the things to consider when securing IPv6 compared to IPv4. Before digging into this topic, however, it is important to remember that while IPv6 may have different security concerns than IPv4, it is not necessarily any more secure than IPv4. Furthermore, the post will focus on those aspects that are different or unique to IPv6, since many of the common best practices for IPv4 networks also apply to IPv6 networks.
