Aleksandr Voloschuk commented on WFLY-3451:
-------------------------------------------

on my server I have these ciphers:

I understand that I need to remove two of them:
RC4-SHA
ECDH-RSA-DES-CBC3-SHA

how do i do?
openssl ciphers ....... ??

> encountered such a problem:
> management of information security vulnerability found on a production environment, namely:
> SSLv3.0/TLSv1.0 Protocol Weak CBC Mode Vulnerability port 8443/tcp over SSL
> RC4-SHA ECDHE-RSA-DES-CBC3-SHA SSLv3
>  they offer a solution:
> This attack was identified in 2004 and later revisions of TLS protocol which contain a fix for this. If possible, upgrade to TLSv1.1 or TLSv1.2. If
> upgrading to TLSv1.1 or TLSv1.2 is not possible, then disabling CBC mode ciphers will remove the vulnerability. Setting your SSL server to prioritize RC4 ciphers mitigates this vulnerability.
> as TLS upgrade we can not, it remains disabling CBC mode ciphers
> our platform is jboss-eap-6.1
