Right now there are a total of 5 different security newsletters from Microsoft. Two for home users and three for geeks, uhh … I mean IT professionals.
If you’re a home user:
* The Microsoft Security Newsletter for Home Users — a bimonthly publication.
* The Microsoft Security Update — a monthly publication.
If you’re an IT type:
* The Microsoft Security Notification Service — a monthly newsletter
* The Microsoft Security Notification Service: Comprehensive Version — same as the one above but it includes modifications to previously published notices.
* The Microsoft Security Newsletter — published monthly
If you have a Microsoft Passport you can sign up for these at the Passport subscription center. If you don’t have a Microsoft Passport you can sign up for one here.
You can also sign up for the Security Notification Service without a Passport. Go here to do that.
