Microsoft Technical Security Notifications
Help protect your computing environment by keeping up to date on Microsoft technical security notifications. Notifications are available in RSS, mobile device and online at the TechNet Security Bulletin Search page.
For IT Professionals
Microsoft's free monthly Security Notification Service provides links to security-related software updates and notification of re-released Microsoft Security Bulletins. The goal of this service is to provide accurate information you can use to protect your computers and systems from malicious attacks. These bulletins are written for IT professionals and contain in-depth technical information.
The free Comprehensive alerts serve as an incremental supplement to the Basic Alerts. It provides advance notification of upcoming security bulletins, security advisories, and timely notification of any minor changes to previously released Microsoft Security Bulletins or Advisories.
Security Advisories Alerts
Microsoft Security Advisories are a way for Microsoft to communicate security information to customers about issues that may not be classified as vulnerabilities and may not require a security bulletin. Each advisory will be accompanied with a unique Microsoft Knowledge Base Article number for reference to provide additional information about the changes.
Microsoft Security Response Center Blog Alerts
The Microsoft Security Response Center (MSRC) blog provides a real-time way for the MSRC to communicate with customers. Topics include day-to-day, "behind the scenes" information to help customers understand Microsoft security response efforts; updates during the early stages of security incidents; and regular postings for the bulletin release cycle.
