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

IDG Contributor Network: Protecting against the next great heist by encrypting in-transit data

Cast your mind back to the last time you were offline – not just when your connection was down, but a time when you were truly, unequivocally disconnected. That time may have been spent sending letters, physically going into a bank to make a deposit or withdrawal, and actually meeting with people to share information.Nowadays, we're far more efficient thanks to our reliance on connectivity and the network. During the past 20 years or so, information has evolved in line with the network, and become largely a digital commodity that can be sent and received with the click of a mouse. Electronic communications now cross organizations and oceans with relative ease, in volumes that seemed unfathomable during the days when postal mail was king. But all of this need for connectivity comes with a downside: criminal elements seeking to steal that data – and make no mistake, something as seemingly innocent as a personal email can be as valuable to a criminal as a bank transaction.To read this article in full or to leave a comment, please click here

What U.S. cities are most prone to malware infections, and why?

An anti-malware vendor has released a list of the 20 most infected cities around the U.S. in terms of malware, and the trend appears to be that cities not known for being technology centers are getting hit the hardest.Enigma Software, which develops the SpyHunter anti-spyware detection software, analyzed more than 25 million different infections on computers in the 150 largest cities in the U.S. and found 2015 was a big year for malware over prior years.Enigma came about its numbers via customers who have its software installed on their machines. The national average was 8.1%, meaning nationwide, but that comes from the number of infections divided by the city's entire population.To read this article in full or to leave a comment, please click here
