On Wednesday I presented "Don't Get Caught with Your Layers Down" along with my intern Bryan on securing Layers 2 and 3 of your network. As I promised the Northeast Ohio Information Security Forum, the presentation is now available for download.
I hope everyone enjoyed the presentation and found value in discussing security issues about the lower layers. Even though these topics are older, we believe they still hold value. Bryan and I developed this presentation after discussing that everyone is currently focused on the protecting the upper layers of the stack. We are starting to neglect the lower layers again.
There are a lot of easy Layer 2 and 3 restrictions that can be implemented on your network that will not cost you anything extra. Your infrastructure vendors should be implementing most of these options in their products.
