Hi Rohit, 1. does changing in httpd.conf reflects the setting for apache2? Use the nmap script as suggested below to identify ssl versions on installed system vm template. Check the suggested change works or not.

TLSv1.2 is the latest to be used and suggested default, ssl protocol and the ciphers we use leads to vulnerability, the settings for these as well should be available in similar config file. In our code, search for TLS leads to usage at places, and assumption is that it should negotiate the protocol version from configured and available latest version to least, so if TLSv1.2 is configured on server and client supports it, then it should work. http://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/118518-technote-esa-00.html Regards, Santhosh ________________________________________ From: Rohit Yadav [rohit.ya...@shapeblue.com] Sent: Tuesday, November 04, 2014 2:04 AM To: d...@cloudstack.apache.org Cc: users@cloudstack.apache.org Subject: Patched 4.3.1 SystemVMs (was Re: git commit: updated refs/heads/master to 88acc9b) Hi again, > On 04-Nov-2014, at 6:01 am, Santhosh Edukulla <santhosh.eduku...@citrix.com> > wrote: > > Apart from SSLv3, we may want to disable TLS1.0, TLS1.1, as they have similar > vulnerabilities. If we don’t support TLS v1.0, it will break console proxy on IE etc. Further, what vulnerabilities do TLS v1.0 and v1.1 have?
