In order to understand a hazard you have to know how it operates. I thought about this next piece for a couple of days. By writing about it am I promoting its use by giving information to those who might do harm in the future. Or, does the gain exist in that you have more information and understanding of how denial of service attacks work. I figure someone who wants to do harm can find the information elsewhere so I came down on the side of getting information into your hands (really heads).
See How to Plan and Execute an act of Electronic Civil Disobedience (ECD) for some basic information on how a denial of service attack can be orchestrated. There is a PDF at the link above.
Later today I'll comment more on cyber terrorism in another blog post.
