Cisco Security Good "Oldies"

Forgive me for sharing a little bit old documents here. Indeed they are not too old - published in 3-4 year ago. But people in IT usually treat documents released more than 6 months are "old".

In my opinion, if an "old" document is still referred by key vendors/parties, I would treasure the document's high value, and its importance. Also, some concrete standpoints are always true in IT arena.. Eg. 7 layers, Virus is always bad, Firewall is always good for your health, etc...

Please find the following documents from Cisco that I recommend. They are good oldies.  :D
