Microsoft has released a new webcast for E-mail Security in their web site.
This month’s live Security360 Webcast takes place Tuesday, Dec. 20. More details can be found at http://www.microsoft.com/events/series/mikenash.mspx.
I can recommend you to browse http://www.microsoft.com/technet/security/default.mspx as a top level page to find out what's important with security from a technical perspective.
Besides, there are a Link called “Want Less Technical Detail?” which is suitable to end users.
You can refer you family or friends to visit this link and view the short videos about preventing
Malware, Phishing, Pharming, Spam...etc.
