Terminate HTTPS traffic from clients, relieving your upstream web and application servers of the computational load of SSL/TLS encryption. As a mitigation you can either try to force them to use another cipher by configuring an appropriate SSLCipherSuite and activate SSLHonorCipherOrder, or embed weak DH params in your Regarding your actual question, which is about the Qualys SSL Labs test tool itself, we'll have to dig into how their rating system works. This was my ssl cipher setting in haproxy which I picked up from a haproxy thread: global ssl-default-bind-ciphers EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECD I am trying to understand ciphers settings in nginx. 1, etc. keystore server. 0 have known weaknesses.
