The Windows Secure Channel (Schannel) component has been a cornerstone of Microsoft's security architecture, facilitating encrypted communications across various Windows services. However, its critical role has also made it a focal point for security vulnerabilities over the years. A notable...

Transport Layer Security (TLS) is at the heart of secure communications on the modern internet, defending data in transit from eavesdropping, tampering, and other threats. For organizations relying on Windows Server to deliver web applications or manage infrastructure, keeping TLS protocols up...

For Windows users relying on Quick Assist to deliver remote troubleshooting, support, or collaboration, a sudden error message halting the session—reading “We ended the connection because the minimum security requirements were not met”—can be deeply frustrating and disruptive. This error...

Microsoft has taken a significant step in bolstering cybersecurity by integrating post-quantum cryptography (PQC) into Windows 11 and Linux systems. This proactive measure addresses the looming threat posed by quantum computers, which have the potential to break traditional encryption methods...

The world of cybersecurity is perpetually on alert, facing an unending procession of new threats that demand fresh defensive measures. However, a new frontier has started to crystallize on the horizon—one that many researchers and technology leaders now call the next great battle in...

The world of cybersecurity is undergoing a tectonic shift as the relentless march of quantum computing edges ever closer to practical realization. For decades, the bedrock of digital security—cryptography—has relied on mathematical problems that are infeasible for classical computers to solve...

Windows Admin Center is a fantastic utility for managing Windows Server instances. With its ability to work from any location, whether on-premises, in Azure, or other cloud environments, it’s an essential tool in the arsenal of IT admins. But let’s be real—technology rarely comes without its...

In the realm of online security, consistent advancements are essential to enhance the protection of digital interactions and safeguard sensitive information. An integral aspect of this security landscape involves Transport Layer Security (TLS) server authentication. Recently, Microsoft announced...

Hi, I have suddenly started getting issues with websites (eg a failure to connect to Sage Pay from a shopping site) - Chrome and Edge browsers. I believe I am up to date with Windows 10 updates and Chrome is right up to date version, just reinstalled to be sure. eg -I tried accessing PC World...

Hello! This is gonna be an odd post in this section, considering that my problems are unrelated to server usage altogether, but maybe someone can help me out here. I got a copy of Windows Server 2008 R2 from the Dreamspark program years ago by attending college. I decided I wanted to use this...

Original release date: November 14, 2017 Systems Affected Network systems Overview This joint Technical Alert (TA) is the result of analytic efforts between the Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI). Working with U.S. government partners, DHS...

Original release date: March 16, 2017 Systems Affected All systems behind a hypertext transfer protocol secure (HTTPS) interception product are potentially affected. Overview Many organizations use HTTPS interception products for several purposes, including detecting malware that uses HTTPS...

Today, a group of eight researchers from across the security industry released a research report on SHA-1 that demonstrates for the first time, a “hash collision” for the full SHA-1 hash algorithm (called “SHAttered”). This is a significant step toward understanding this type of security issue...

In September 2015, Microsoft announced the end-of-support for the RC4 cipher in Microsoft Edge and Internet Explorer 11 in 2016, as there is consensus across the industry that RC4 is no longer cryptographically secure. Today, we are releasing KB3151631 with the August 9, 2016 cumulative updates...

I created this reg file to disable SSLv2, v3 and TLS 1.0 as well as disabling weak encryption cipher suites.

Revision Note: V1.0 (May 10, 2016): Advisory published. Summary: FalseStart allows the TLS client to send application data before receiving and verifying the server Finished message. This allows an attacker to launch a man-in-the-middle (MiTM) attack to force the TLS client to encrypt the first...
