HTTP-6710 - SSL configuration in nginx
To protect the privacy of users, including sniffing of sensitive data on networks, enable SSL/TLS in nginx.
How to solve
Enabling TLS in nginx allows it to encrypt the connection between the server and user. Commonly this is referred to as using a SSL certificate. It is good to know that older SSL protocols (SSL v2 and SSL v3) are considered to be weak and should be avoided. The nginx configuration will still use the related "ssl" option, but that is independent of the actual protocols which are used. For new deployments consider only to use TLS v1.2.
- Enable SSL on the listen statement of an entry, or with "ssl on;"
- Define the certificate
- Define the allowed ciphers
- Define the allowed protocols (SSL / TLS)
- Apply additional measures like SSL stapling
