I have a Windows Server 2016 hosted on AWS EC2 using Plesk Onyx as a hosting control panel. More information To deploy your own cipher suite ordering for Schannel in Windows, you must prioritize cipher suites that are … My point is to why Microsoft would ship it enabled by default on Windows Server 2016 which was released just a couple of months back. Time to disable weak ciphers on IIS Ok, we have a failing test in our CI/CD pipeline that checks the cipher suites – let’s work on fixing it! More information To deploy your own cipher suite ordering for Schannel in Windows, you must prioritize cipher suites that … Important HTTP/2 web services fail with non-HTTP/2-compatible cipher suites. The excuse that its patched on the client side doesn't take away that PCI compliance and other audits will mark IIS and WinServer as insecure.
