Microsoft Security Bulletin MS15-032 (3038314)
This critical security update resolves vulnerabilities in Internet Explorer. For more information, please see Microsoft Security Bulletin MS15-032.
Disabling SSL 3.0
As communicated in our February 2015 security updates blog, today we’re releasing an update that disables SSL 3.0 by default in Internet Explorer 11. Enterprise customers can choose to enable SSL 3.0 for compatibility with their web applications, however we strongly recommend instead that they update their web servers and web applications to use latest security protocols such as TLS 1.2. For more information, please see Microsoft Security Advisory 3009008.
Staying up-to-date
Most customers have automatic updates enabled and will not need to take any action because these updates will be downloaded and installed automatically. Customers who have automatic updates disabled need to check for updates and install this update manually.
