Here*is another top ten cyber security threat for 2008:
***** —*Denial-of-service attacks.
Distributed denial-of-service (DoS) attacks*in cyberspace*are one of the most difficult threats to defend against.***Criminals or terrorists,* for example, can use*botnets to send a large number of queries or other malicious traffic*to servers, effectively shutting them down.**A*successful, sustained denial-of-service attack against*critical infrastructure, such as the*DNS root servers, could potentially shut down the Internet.****
The U.S. government once warned the American private financial services*industry of a looming al Qaeda DoS attack against online stock trading and banking web sites.* Blackmailers and extortionists often*threaten DoS attacks against their victims and the threat of DoS attacks is very real for high-profile web servers such as banks, credit card payment gateways and other critical infrastructure.*
Denial-of-service attacks remain a serious threat in 2008.
