Configure SSL/TLS Strong Encryption
You can configure SSL/TLS strong encryption for Tenable.sc Director-client communications to meet the security needs of your organization. For more information about Tenable.sc encryption, see Encryption Strength.
To configure SSL/TLS strong encryptions for Tenable.sc Director communications:
/opt/sc/support/conf/sslciphers.conffile in a text editor.
Add the following content at the end of the file:SSLCipherSuite <cipher you want to use for SSL/TLS encryption>
# SSL Ciphers
SSLProtocol ALL -SSLv2 -SSLv3
Restart Tenable.sc Director, as described in Start, Stop, or Restart Tenable.sc Director.
Tenable.sc Director restarts.
In /opt/sc/support/logs, open ssl_request_log.
The log file text appears.
Verify the configuration in ssl_request_log matches the cipher you specified. If the configuration and cipher do not match, investigate the following:
Confirm that you provided the cipher using correct syntax.
Confirm that your browser supports the cipher you provided.
Confirm that you do not have other applications installed that redirect or layer additional encryption for SSL traffic.
