During a recent security audit, I was informed that our Sonicwall device needed to support a stronger encryption algorithm for 443 TCP/HTTPS connections. The auditors reported that 443 was using the RC4-128 Bit cipher. I found an option for SSL VPN (which we are running over 4433) and I changed that to an AES cipher, but I do not see an option to change the cipher for 443 connections to the Sonicwall.
Is it possible to update the cipher setting for port 443 connections?
The only 443 connection we use is for configuration management.
I am running a Sonicwall NSA240, SonicOS Enhanced 126.96.36.199-30o
