Does any one has the steps to secure Listener for 11g rel 2 (11.2.0.3) using SECURE_REGISTER_LISTENER ?
We are using TCP and using Data guard but NOT RAC.
I put the below entry in the listener.ora and did the stop and start of the listener but not sure if there is some additional steps. ( I saw on Google that there is some sql to update the local_listener but some just put this below  entry and reload the listener).
I will check with experts.

I did the below 2 steps:---
1. Update listener.ora file with this entry
SECURE_REGISTER_LISFLLPRD = (TCP)
(Where LISFLLPRD  is my listener name)
2. stop and start the listener.

Also, Is there any patch to be applied? We are current on CPU patches and already applied Oct CPU patches.

As far as the listener goes, I would follow the following doc on Oracle Support:
Using Class of Secure Transport (COST) to Restrict Instance Registration (Doc ID 1453883.1)

Latest patches can also be found on Oracle Support's site.

I would caution you to not just patch because it is available.  Oracle loves to sneak new bugs into patches.

You need to make sure you do a pretty decent regression test after patches are applied.
