• TLSv1.3

Cipher Suites

• ECDHE-ECDSA-AES256-GCM-SHA384
• ECDHE-RSA-AES256-GCM-SHA384
• ECDHE-ECDSA-CHACHA20-POLY1305
• ECDHE-RSA-CHACHA20-POLY1305
• ECDHE-ECDSA-AES128-GCM-SHA256
• ECDHE-RSA-AES128-GCM-SHA256
• ECDHE-ECDSA-AES256-SHA384
• ECDHE-RSA-AES256-SHA384
• ECDHE-ECDSA-AES128-SHA256
• ECDHE-RSA-AES128-SHA256

In on-prem installations of IriusRisk, you can validate the use of these protocols and ciphers by viewing the contents of the /etc/nginx/conf.d/irius.conf file using this command:

docker exec -ti iriusrisk-nginx cat /etc/nginx/conf.d/irius.conf

You can find the SSL configuration settings after the production config section in irius.conf:

ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';
