Explain a distributed denial of service attack
A distributed denial of service (DDoS) attack may take the form of a SYN flood or smurf attack. The distinguishing feature of the DDoS is the sheer scope of the event. The perpetrator of a DDoS attack may employ a virtual army of so-called zombie or bot (robot) computers to launch the attack. Since vast numbers of unsuspecting intermediaries are needed, the attack often involves one or more Internet Relay Chat (IRC) networks as a source of zombies. The perpetrator accesses the IRC and uploads a malicious program such as a Trojan horse, which contains DDoS attack script. This program is subsequently downloaded to the PCs of the many thousands of people who visit the IRC site. The attack program runs in the background on the new zombie computers, which are now under the control of the perpetrator. Via the zombie control program the perpetrator can direct the DDoS to specific victims and turn on or off the attack at will.
