Internet security research firm Team Cymru has begun publishing a four part series explaining the hows and whys of denial of service attacks.
The series plugs a long standing knowledge gap. ISPs, for example, can learn about DDoS attack trends from the likes of Arbor Networks, but if you're running a small online business then it's all very confusing, which is where Team Cymru's research (YouTube channel here
) comes in.
An accompanying paper (published here
on Monday to coincide with the release of the second video in the series) explains the various types of DDoS attacks (revenge, extortion, disrupting the business of a rival, political protests etc). It outlines the motivations of miscreants and suggests countermeasures.
