## 2.4 Disable SSLv3

By default, SSLv3 should be disabled.

Specifying the `weblogic.security.SSL.protocolVersion` system property in a command-line argument that starts the WebLogic Server lets you specify the protocol that is used for SSL connections.

The following command-line arguments can be specified so that WebLogic Server supports only TLS connections:

`- Dweblogic.security.SSL.protocolVersion=TLS1`

Note:

If you don’t specify the above property, WebLogic assumes SSLv3 by default.
