Information in this document applies to any platform.

Goal

This document explains steps to disable weak SSLCipherSuites used by the EM 13c OMS, Agent and WLS.
This procedure is useful if a security policy determines usage of only the strong cipher suites for the communication between the OMS and Agent, for EM Console access or if a security scan reports a Weak CBC Mode Vulnerability for EM components.

If you want to disable the weak cipher suites to address any security exposure, then check the information listed below:

1. Collect the scan report and note the port number on which the exposure is reported.
2. Check the EM process running on that port, by referring to port numbers in <EM INSTANCE HOME>/em/EMGC_OMS1/emgc.properties file.
3. Follow the solution provided in this document for respective process or application.
