What is a DoS/DDoS Attack ?
Internet Partners: Frequently Asked Questions (FAQs)Short for Denial of Service attack, a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols. For all known DoS attacks, there are software fixes that system administrators can install to limit the damage caused by the attacks. But, like viruses, new DoS attacks are constantly being dreamed up by hackers.

Infamous examples include the Blaster Worm, Code Red, Code Red II, SQL Slammer, and MyDoom. DDoS attacks enlist the help of dozens to thousands of unsuspecting ‘zombie’ servers, who unwittingly participate in the attack.Related Questions

What are the recent DoS/DDoS attack trends and how IG 200/2000 protect against the evolving threats?
Intruguard Devices - FAQsIn earlier days (a few years back), most attacks used to be spoofed and we do a great job in preventing spoofed floods through SYN, ICMP, UDP flood prevention etc. through SYN cookies and other mechanisms. These days we are seeing a lot of attacks which come from Botnets and limited IPs. We do an excellent job of stopping these attacks through our patent pending source tracking mechanisms which punish attackers and limit number of packets/source, connections/source, etc.

Georgia Tech Information Security CenterNo. From a simplistic perspective, the best solution is to secure computers from being hijacked and used as attack platforms. This cuts the problem off before it can ever manifest. Thus many experts suggest that we "pull together as a community" to secure our internet computers from becoming unwitting accomplices to such malicious intruders.

Georgia Tech Information Security CenterA website DDoS is executed by flooding one or more of the site's web servers with so many requests that it becomes unavailable for normal use.

DDoS attacks typically take advantage of several computers which simultaneously launch hundreds of thousands of requests at the target website.

I tried running DOS MAME under DOS about a year ago. I couldn't get the drivers for my sound card set up under DOS so I had to run without sound. Without sound, DOS MAME was at most frameskip 1 faster than mamew without sound, if that much.
Related QuestionsWhy is the compiler DOS based, not Windows?
HI-TECH Software Frequently Asked QuestionsWell, firstly we are developing a Windows user interface. This will be Win-32, i.e. it will run under Windows 95 and Windows NT. But since the compiler is a non-graphical application, and the DOS interface runs quite happily under all flavours of Windows already, it has not been as high a priority as making sure that the basic functionality is top-notch. In other words, we believe an excellent compiler with a DOS front-end is better than an average compiler with a Windows front end.
