Cyber Attacks on Governments

Forum Introduction
Blank South Korean ministry Web pages; AFP/Getty On the Fourth of July, cyber attacks started targeting computers at the White House, the Pentagon and other major U.S. government agencies. The New York Stock Exchange and the South Korean government were also targets. Who and what are behind the attacks? Two experts take your questions.
QUESTIONS
How can the average person protect his or her computer or Web site from being infected and used in similar cyber attacks?
What software vulnerabilities were exploited in the attacks? How has the software company responded?
I visited a foreign Web site and was greeted with a message saying I was under a malware attack. What should I have done?
When another nation launches a cyber attack on the United States government, why is it never discussed as an act of war?
How did malicious code get planted on so many computers? Did all the infected computers have to be turned on to be hijacked?
Can computers or servers be programmed to ignore repeated contacts from the same IP address to lower the risk of such attacks?
Do you foresee average Internet users benefitting from Internet2 community research?
Government security aside, is it sensible to expose one's personal financial to the Internet through online banking and brokerage?
Can adaptive software in routers be used to cope with cyber attacks?
Andy of St. Louis, Mo., asks:
The closed Internet2 community of mostly research universities and governments is working to develop safer and faster computer-networking technologies. Do you foresee the average Internet user benefitting from their research?
ANSWERS

Randy Sabett responds:

Advances continue to be made in numerous areas of research, including those related to network and online security. I believe that such advances will provide user benefits in the near future. I think we have reached a point where enough momentum exists that we can develop the "culture of security" I mentioned earlier. This, in combination with the focus being paid by the Obama administration to this issue, will result in such advances being put into use. As a result, the deployment of safe and faster technologies will actually stand a chance of being successfully adopted and deployed.

A significant focus of the Internet2 community is in the area of authentication (read this for more information and technical background). As you can see in my response below related to financial transactions, I believe authentication continues to be one of the most important technology areas in terms of providing significant benefits across the board for all stakeholders. Many of the problems that exist today are due to communications or connections with unknown entities. If you receive an email saying "click on this important document that I just sent you" and it appears to be from a friend, do you actually know that your friend sent it? This relates to the issue of human authentication. More subtlety (but perhaps even more importantly), does your computer know that it is talking to the right computer at the other end for a particular communication or could it be an imposter computer? This relates to the issue of device authentication. Advances in both areas will offer significant benefits.

Advancements that occur in the academic and government areas eventually benefit the general public as the solutions they find become part of what is commercially available.
