Steve Gibson Discovers Roots of Denial of Service Attacks

Slashdot pointed out an article that Steve Gibson wrote, documenting his efforts to defend against a series of Distributed Denial of Service Attacks against his company's Web Site, GRC.com. This is one of the most outstanding investigations into "the community" that launches DDoS attacks that has ever been put together.

There are so many useful pieces of information to take away from this, that we consider it required reading for:

  • Internet Service Providers,
  • companies with mission-critical Web Sites on the Internet,
  • consumers and small businesses who have PCs on broadband connections, but have not educated themselves about network security.

Even if you have installed a "personal firewall" software product on your PC, you should read this article. The article provides documented proof of the performance of ZoneAlarm and BlackICE Defender against Sub7 Trojan attacks. We were surprised at the results.
