Last time, we started looking at the upcoming .Net MyServices technology offering from Microsoft with a peek into its mechanisms. Today, we'll see why this user-centric technology is important for you, the network manager, to understand.
There are two reasons you need to take an interest - security and money.
Security first. Even though Bill Gates' famous memo from last month calls for all of Microsoft to put security at a higher priority than new functionality, we'll need to keep a very close eye on MyServices, which has a number of areas that could cause security problems. The Passport service, which lies at the heart of MyServices as its authentication mechanism, has already been compromised at least once, and it could happen again. The messages exchanged by .Net servers and MyServices clients use well-documented protocols, such as XML and Simple Object Access Protocol (SOAP), which can be compromised if not properly implemented.
There is also the problem of criminal servers. Nothing but good sense prevents users from being enticed to share information (such as credit card numbers) with servers set up by criminals in a massive, worldwide con game. While you can't do much to protect your users when they're at home (except, possibly, to warn them), you can take actions on your network to block access to these rogue sites and the incoming messages they use to entice your users.
Today's firewalls and antispam agents can be easily adapted to this use. The exact details won't be available until we know more about the structure of MyServices, but we'll keep you informed.
Next issue: The money angle.
