A DoS attack is generally orchestrated by an attacker using a single compromised node. DDoS attack is distributed. Typically, an attacker first compromises a number of nodes (called zombies) and then from these bunch of compromised nodes, sends the attack with the purpose of bringing down the service quickly. 2) See Notes (slide 8, Challenges, 2/01/10) 3) See the Handout from the class webpage: http://edition.cnn.com/2005/TECH/internet/01/20/evil.twins/index.html For guidelines on how to mitigate evil twin, see the link on the class webpage: http://www.eweek.com/article2/0,1759,1755275,00.asp 4) a.
