I've received a bad bad grade over on SSL Labs for my view security server (5.3.1), most notable is "This server supports insecure Diffie-Hellman (DH) key exchange parameters (LogJam)"
I've searched high and low for a way to change this, and keep getting stuck on instructions describing things that don't exist on my server (i.e. Jre/security.properties) and this being an inherited system, it's hard to tell if the instructions are wrong or my server is more broken than I thought.
Any help or places to look would be greatly appreciated.
Horizon View 5.x went end of general support on 2016/09/14 and end of technical guidance on 2018/09/14. Instead of trying to modify this environment that you inherited where you could end up in a situation with no support I would urgently advise upgrading or migrating to 7.x (Horizon View 6.x goes end of general support in less than 6 months (2019/06/19)).
