- Greg Ferro published some great thoughts on certifications versus experience. While a lot of people tend to disagree with him (at least a bit ... myself included), he has some very good points.
- Joe Harris posted the "IOS order of operation" list. Unfortunately it looks incorrect; I'm positive that in some cases NAT looks at the packet (and creates the translation) even if the inbound ACL drops it.
- Anyone who has ever been involved in security must read Security Maxims from Roger Johnston (hat tip to Bruce Schneier).
- I got promoted to holy cows. At least I have good company. BTW, if you're concerned about the security of your switch configuration, check what NSA has to say about it.
- Thinking problem management has a great post explaining why you need service documentation.
- Ethan Banks is back and writes about RGEs (Resume Generating Events).
- Anthony Sequeira writes about transparent firewall on ASA/PIX.
