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.

Verifying Our Digital Signature
Pretty Good Privacy (PGP) is an Internet standard for digitally signing and encrypting e-mail and other documents. The Microsoft Security Response Center (MSRC) uses PGP to digitally sign all security notifications. However, it is not required to read security notifications, read security update information, or install security updates. You can obtain the MSRC public PGP key at the MSRC Security Notification PGP Web page. Numerous third-party vendors produce PGP-compatible applications for a variety of platforms, but Microsoft cannot recommend the right solution for your environment.
