How encryption keys could be stolen by your lunch

Israel-based researchers said they’ve developed a cheaper and faster method to pull the encryption keys stored on a computer using an unlikely accomplice: pita bread.The new study builds on research into what can be learned from the electronic signals that waft from computers while performing computations, often referred to as side-channel attacks.By studying the electronic signals, researchers have shown it is possible to deduce keystrokes, figure out what application a person is using or discover the secret encryption keys used to encrypt files or emails.To read this article in full or to leave a comment, please click here

iPhone 7 rumor rollup: Heavy metal! Fingerprints! A kinda-sorta-maybe release date!

Would you believe there are people so interested in Apple and all of its works that they want to know what’s going on with the next generation of the iPhone before it even comes out? My editors assure me that this is the case. So, despite the obvious lunacy of the idea – I mean, surely it’s enough to know that there will probably be another one coming out at some point, right? – I am stepping in to provide you with the latest scuttlebutt on what may or may not be the iPhone 7.+ ALSO ON NETWORK WORLD: Review: The best password managers for PCs, Macs, and mobile devices + FBI investigates St Louis Cardinals over Houston Astros hacking +To read this article in full or to leave a comment, please click here

Optimizing software defined data center

The recent Fortune magazine article, Software-defined data center market to hit $77.18 billion by 2020, starts with the quote "Data centers are no longer just about all the hardware gear you can stitch together for better operations. There’s a lot of software involved to squeeze more performance out of your hardware, and all that software is expected to contribute to a burgeoning new market dubbed the software-defined data center."

The recent ONS2015 Keynote from Google's Amin Vahdat describes how Google builds large scale software defined data centers. The presentation is well worth watching in its entirety since Google has a long history of advancing distributed computing with technologies that have later become mainstream.
There are a number of points in the presentation that relate to the role of networking to the performance of cloud applications. Amin states, "Networking is at this inflection point and what computing means is going to be largely determined by our ability to build great networks over the coming years. In this world data center networking in particular is a key differentiator."

This slide shows the the large pools of storage and compute connected by the data center network that are used Continue reading

Coming Updates to the CCIE Program

With everything going on in the industry, what is happening to the CCIE program?

I recently watched a webinar on coming updates to the CCIE program. I have also been talking to the CCIE and CCDE program managers which I am proud to call my friends. The certifications are a big part of Cisco’s business, people are afraid that certifications will lose value as Software Defined Networking (SDN) gains more traction in the industry. What is Cisco’s response to the ever changing landscape of networking?

We have already seen Cisco announce the CCNA cloud and CCNA industrial which shows that Cisco follows the market. Will we see a CCIE cloud or CCIE SDN? Doubtful… Why? Because SDN is not a track in itself, it will be part of all tracks… The CCIE DC will be refreshed to include topics like Application Centric Infrastructure (ACI) in the blueprint. When? It’s not official yet which means you have at least 6 months. My guess is that we will see an announcement before this year ends which would mean that the update is around a year away.

CCIE DC is the natural fit for SDN. What about the other tracks? Expect other tracks Continue reading

Windows-Linux File Synchronisation

My development environment usually consists of a host machine running Windows and a development Linux “headless” virtual machine. I create and edit files in a Notepad++ text editor and then transfer them over to the Linux VM. Until recently I’ve been using a hypervisor-enabled “shared” folder. However, Windows file system emulators in Linux do not support symbolic links and therefore breaks a lot of applications that rely on them. This prompted me to start looking for a new way to sync my files. That’s how I came across this new amazing file syncing app called Syncthing. Why is it amazing?

  • It uses peer-to-peer architecture. User traffic is not uploaded to a centralised server and is transferred directly between peers.
  • It is open-source. It doesn’t use any proprietary syncing protocols like BTSync.
  • As the result of open-source nature it has big community support with clients, wrappers and extension available for any major platform.
  • It is secure. All transfers are TLS-encrypted.
  • It’s simple to use. Windows version installs like any other Windows app, Linux version, like any other Linux app, will take a little tinkering.
  • It’s written in Golang, an extremely popular language amongst professional programmers and surely these guys can’t be Continue reading

Happy Father’s Day, from the Father of Hyperconvergence

One thing that's cool about my job as a tech business publication editor is getting to meet industry pioneers, as I did by phone this past week with Mohit Aron, widely considered to be the Father of Hyperconvergence as a co-founder of Nutanix and now the founder and CEO of startup Cohesity (you can read my Q&A with Aron here). Over the years I've met a bunch of industry Fathers, including Bob Metcalfe of Ethernet fame and Vint Cerf of Internet fame, as well as industry Mothers, like Radia Perlman of Spanning Tree fame.To read this article in full or to leave a comment, please click here

Message Queues: RabbitMQ in Go and Python

I’ve been playing around with various message queue implementations for a few projects, and wanted to write a quick post on some basics. Message Queues Before we get into the detail of RabbitMQ, it’s worth briefly defining exactly what a message queue is, of which RabbitMQ is just one implementation. You may have heard message queues described as a “Publish/Subscribe” system, or “Pub/Sub” for short. This is a style of communication between software elements, where some components publish messages onto a queue, and others subscribe to that queue and listen for messages published on to it.

What the FCC’s new robocall rules mean for your company’s marketing efforts

Marketers now face tougher restrictions on their use of “robocalls” and other automated telemarketing techniques thanks to a new set of declaratory rulings issued by the FCC on Thursday.Although the Telephone Consumer Protection Act of 1991 requires prior consent for autodialed, prerecorded or artificial voice calls to wireless and residential wireline numbers, marketers have still been able to exploit numerous loopholes to make questionable calls anyway.Now, in response to thousands of consumer complaints and nearly two dozen petitions, the FCC has affirmed consumers’ rights to control the calls they receive and made it clear that telephone companies can use robocall-blocking technology to help them.To read this article in full or to leave a comment, please click here
