How to test
After restarting the server run the following query to see if the ssl settings are correct: show variables like '%ssl%';
DB2
Tested with Version
We do not test this here, since we only reference other papers for DB2 so far.
Settings
ssl_cipherspecs:
In the link above the whole SSL-configuration is described in-depth. The following command shows only how to set the recommended ciphersuites.
- Recommended and supported ciphersuites
db2 update dbm cfg using SSL_CIPHERSPECS TLS_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA

PostgreSQL
Tested with Versions
- Debian Wheezy and PostgreSQL 9.1
- Linux Mint 14 nadia / Ubuntu 12.10 quantal with PostgreSQL 9.1+136 and OpenSSL 1.0.1c
Settings
To start in SSL mode the server.crt and server.key must exist in the servers data directory $PGDATA.
| Starting with version 9.2, you have the possibility to set the path manually. |

It’s recommended to read Security and Authentication in the manual. PostgreSQL Documentation on Secure TCP/IP Connections with SSL. PostgreSQL Documentation on Client Authentication.
How to test
To test your ssl settings, run psql with the sslmode parameter: $ psql "sslmode=require host=postgres-server dbname=database" your-username
