Re: SDN is not just for flexibility
The IT landscape might be our modern day version of the wild wild west.  Security issues that get lots of media attention are easy to react to. 

The truth of the matter is that security vulnerabilities that affect consumers are likely to be much more prevalent than the average person realizes.  Perhaps it is time for internet security software developers to step up to the plate and address this growing need.  If I go to a given website, there should be a quick and easy alert system in place to let me know where it currently stands as well as its security track record.

Re: SDN is not just for flexibility
Most   of the internet services have been badly affected by Heart Bleed bug. I have recently hosted my website on Cloudways PaaS Click&Go. Thank God Cloudways is secure. Try out Pere's 5-step solution to keep your websites safe:

·         Assess the data               

·         Coordinate with others facing the same bug

·         Gather Information

·         Re-issue SSL certificates

·         Re-set confidential information

Open/closed
Does availability of programmable data path elements depend on an open-protocol-based SDN implementation, or is this also available to shops that buy a Cisco stack or another proprietary offering?

Re: SDN is not just for flexibility
SDN is a fundamental change to the traditional network. It's a new framework/architecture instead of a standalone technology. From networking protocol perpsective, it provides a proactive approach to mitigate possible flaws/vulnerabilities. But I am afraid it will take longer time to establish SDN framework than developing the security patch - there is still some distance from the ideal state.

SDN is not just for flexibility
Lori MacVittie makes a good point.The software-defined network is good, not only for the flexible protocols you may implement, but for the the short term things you can do as well. The ability to isolate and reject the requests that may now be creeping into the data center as a result of HeartBleed is a necessary weapon in the netwoork manager's arsenal.
