Growing Up the Internet

Roger A. Grimes has written an interesting article for InfoWorld discussing the reality that relatively minor players can take down large segments of the internet and that many critical systems rely upon the internet. He suggests the only way to overcome these attacks requires an upgrade of the internet, not just piecemeal upgrades of various corporations or endpoints.

He recommends two strategies to accomplish this upgrade:

  1. Use of more secure methods of authentication to ensure traffic is being sent from legitimate sources to legitimate recipients.
  2. The creation of centralized services that would be able to analyze web traffic and determine when hostile attacks were occurring and inform other network entities about these.
