Minimum Advertised SSL/TLS Version

The sslmin option sets the minimum allowed TLS version. Use this option to mitigate the use of older, more vulnerable versions of TLS.

When the tls-version parameter is set to compatibility within a tls-profile configuration element, the sslmin option specifies the lowest TLS version allowed. By default, when tls-version is set to compatibility, the Oracle Communications Session Border Controller advertises only TLS1.1 and TLS1.2. To advertise TLS1.0 as well, set sslmin to tls1.0.

In security-config, the sslmin option values can be: tls1.0, tls1.1 or tls1.2.
