Comments on: USFK Says Their Webpage Not Attacked By North Korean Hackers http://rokdrop.com/2009/07/12/usfk-says-their-webpage-not-attacked-by-north-korean-hackers/ Korea From North to South Sat, 20 Mar 2010 00:17:12 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: JoeC http://rokdrop.com/2009/07/12/usfk-says-their-webpage-not-attacked-by-north-korean-hackers/comment-page-1/#comment-348678 JoeC Mon, 13 Jul 2009 10:03:46 +0000 http://rokdrop.com/?p=14815#comment-348678 A denial of service attack is not an internal attack; such as having your system infected by a worm or virus. It's an external attack where your gateways are bombarded with requests from thousands of outside computers simultaneously and incessantly. The system becomes overwhelmed and cannot process legitimate requests. The most common defence is to tell your systems to ignore traffic from the suspect sources. When you can't narrow down the sources of the attack, then you only accept requests from your own trusted domain. In the case of USFK, that trusted domain is the .MIL Generals LaPorte and Bell used to have their kachi kapshida on USFK.mil where they had a dialogue with the Korean public published in hangul. If that is no longer part of the USFK mission, then I guess USFK is telling the truth and shutting down public access as a precaution during the attacks is not a mission impact.

No damage was reported on US government sites, perhaps with the exception of denial of use for outside sources. The biggest losers would be government sites that do not routinely update against virises.
