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. For EM 12c,follow <Note1477287.1> EM 12c:How to Disable Weak SSLCipherSuites Used by Enterprise Manager Cloud Control
