Docker Networking on Software Gone Wild

A year and a half ago, Docker networking couldn’t span multiple hosts and used NAT with port mapping to expose container-based services to the outside world.

Docker is the hottest Linux container solution these days. Want to know more about it? Matt Oswalt is running Introduction to Docker webinar in a few days.

In August 2014 a small startup decided to change all that. Docker bought them before they managed to get public, and the rest is history.

The Unspoken Benefits of Open Networking

I have noticed a lot of very premature dismissal of a growing trend in the networking industry, which is the rise of open network operating systems. Nearly every post-announcement discussion that I hear among peers tends to sound something like this:

I am not Facebook or Google. I don’t want to install third-party software on my switches, so this “open networking” movement is not relevant to me or my organization.

I believe this sentiment is based on an incomplete understanding of all of the benefits of open networking. I’d like to bring up some additional points that aren’t being discussed as much as others, as it pertains to open network operating systems. I believe these additional benefits apply to a very large spectrum of organizations, not just the top 1% webscale companies.

This is not to say that closed-source operating systems do not have a place anymore, or that the current participants in the open networking ecosystem are perfect, or that we have anything but a long road ahead of us in this journey…my point in writing this post is simply to illuminate parts of the conversation that deserve more attention.

SDN and Network Automation: Splitting Hairs?

At the recent Network Field Day 11, there were several discussions at the Cisco offices after the Cisco folks left the room. One of these discussions, led by Terry Slattery, was centered around SDN, and I think it’s worth a listen/watch (only about 20 minutes): In this video, I made the argument that SDN should be limited to a very specific definition, which eliminates the management plane from the conversation entirely (around 5:40).

IDG Contributor Network: Employee data often isn’t encrypted as well as customer data, report says

Employee bank records are among the sensitive details that companies are failing to protect adequately through encryption, a recent study has uncovered. While enterprises now take customer data protection seriously, in many cases they're ignoring their workers' needs for security, according to encryption product vendor Sophos.Not always doing it Sophos says that it found almost half (47%) of the companies it surveyed had owned-up to not always encrypting employee healthcare information when it stored that data. And close to that number (43%) failed to always encrypt workers' Human Resources employee files.To read this article in full or to leave a comment, please click here

All your old-tech passwords belong to us, for just $17

Today's lesson on how the cloud can work against you, as well as for you, is about your passwords and keys, and how they're becoming useless. I've stolen a link from Mark Gibbs to help.Let's say you've been letting older security encryption methods live out their life in the pastures of your data center. CloudCracker, using massively-induced dictionary attacks, can make mincemeat from a frightening number of password key-exchange seeds.For just $17 per, CloudCracker can conveniently crack the following password seeds: WPA/WPA2, NTLM, SHA-512, MD5s, and/or MS-CHAPv2. No tears, please. And yes, cracked like an egg, a $17 egg. Certainly no one would abuse such a service, would they?To read this article in full or to leave a comment, please click here
