Hi Team,

Our client is using Version : PostgreSQL 9.6.17 , they have done vulnerability
assessment and found that :

- TLS version 1.0 Protocol detection
- The remote service encrypt traffic with older version of TLS

We suggested the below changes in PostgresSQL.conf

ssl_ciphers = 'HIGH:!aNULL' *OR *ssl_ciphers = 'HIGH:TLSv1.2:!aNULL'
ssl_prefer_server_ciphers = on
ssl_ecdh_curve = 'prime256v1'

But the scan report is still the same. Can you please guide with the
configuration in the present Postgres version to remediate it.

Thanks
