Jack Daniel, a self-professed curmudgeon and owner of a truly magnificent beard, has a very direct and non-nonsense perspective on the topics he chooses to write about. He is also a bit of a fibber about that curmudgeon part. Jack is a great friend and has done as much for the information security community as anybody I can think of.
He is actively involved in the Security BSides movement and sits on the board of the National Information Security Group (NSAIG.) He writes on a variety of topics and I enjoy his work. Pop his blog, Uncommon Sense Security, in the must-read folder in your RSS reader.
Here are some recent contributions as a sample:
You can also follow Jack on Twitter. He is @jack_daniel there.
