Information in this document applies to any platform.


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/ 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

4.The following variable paths are used in this note:

<EM_INSTANCE_BASE> = Base Location where EM OMS is installed
<GCDOMAIN HOME> = <EM_INSTANCE_BASE>/gc_inst/user_projects/domains/GCDomain/
