Don't be lulled by firewalls

The recent Nimda virus caused untold damage to companies throughout the world. IT administrators spent days disinfecting and patching infected systems, as well as belatedly applying current security patches to systems running Microsoft's Internet Information Server software. Nimda did an incredibly thorough job of finding systems running IIS, even if those systems weren't really Web servers.

The Pen Is Mightier than the Electronic Signature

It's not often that you can get Internet legislation passed nearly unanimously in both Congress and the U.S. Senate, then signed with a flourish by the president.

Lack of a clear focus for PKI, coupled with a lack of interoperability across all PKI-using systems, will cause untold delays in getting products to work together.
