Description Martin Kosek 2017-02-23 14:33:36 UTC
+++ This bug was initially created as a clone of Bug #1367026 +++

Description of problem:
Prepare, document and test a procedure for configuring IdM Server (FreeIPA) by enabling only ciphers TLS 1.2 or stronger.

This procedure will ensure that:
- all primary IdM components (ipa-server, 389-ds-base+openldap, pki-core+tomcat, httpd+mod_nss, krb5-server, sssd) support TLS 1.2 and can be configured to only support that cipher suite or stronger.
- Administrator has a procedure to strengthen IdM cipher suite in case a vulnerability similar to POODLE (IdM Bug 1154687) emerges and allowed ciphers become vulnerable.

There isn't any document for RHEL 7. Do we need one?

Since there are some differences in the configuration, I think we should have a guide for RHEL 7. From development perspective, it would be a minor effort - simply testing the steps mentioned above.

Comment 1 Martin Kosek 2017-02-23 14:37:50 UTC
This is the original documentation from RHEL-6.9:

~~~~
IdM servers can now be configured to require *TLS* 1.2 or better

Version 1.2 of the Transport Layer Security (TLS) protocol is considered significantly more secure than previous versions. This update enables you to configure your Identity Management (IdM) server to forbid communication using protocols that are less secure than *TLS* 1.2.

For details, see the following Red Hat Knowledgebase article: https://access.redhat.com/articles/2801181.
~~~~

We need similar documentation and steps for RHEL-7.x.
