How to Configure SSL/TLS Protocols in Oracle WebLogic Server - Disable SSL 2.0/3.0 and Enable TLS 1.2 / TLS 1.3

The content of this document was formerly within <Note 1936300.1>, "How to Change SSL Protocols (Disable SSL 2.0/3.0) in Oracle Fusion Middleware Products", primarily written to address the SSL V3.0 "Poodle" Vulnerability, CVE-2014-3566. While still applicable to address Poodle (disabling SSLv3), configuring SSL/TLS protocols is a general administration task to meet a company's business needs for an application using SSL/TLS.

If you have other Oracle Fusion Middleware products installed or using third-party applications, care should be taken before updating the JDK or restricting SSL protocols. Some applications may not support all protocols. Check the certification or the requirements of the other installed components or applications making secure connections. Since updating the JDK may be the biggest change to gain new SSL features for WLS, see <Note 1492980.1>, "How to Install and Maintain the Java SE Installed or Used with FMW 11g/12c Products".

• Following this should be the first step:

  - For WLS, this will also provide the PSU and JDK updates affecting SSL protocol and cipher usage
