Cyberattack grounds planes in Poland

LOT Polish Airlines was forced to cancel 10 flights scheduled to depart from Warsaw’s Chopin airport on Sunday after hackers attacked its ground computer systems.The IT attack, which was not described in detail, left the company unable to create flight plans for outbound flights, grounding around 1,400 passengers.The company said that plane systems were not affected and aircraft that were already in the air were able to continue their flight or to land. The incident only affected the ability of planes to depart from the airport for several hours.It’s not clear what kind of attack it was and whether it was the hackers’ intention to ground planes or if the systems were taken offline as part of incident response procedures.To read this article in full or to leave a comment, please click here

Why I Support Certifications

I’m betting that I could take my certifications off my resume and still have a fair chance at finding a job. It’s a guess, of course, and I’ve never tried any sort of an experiment towards finding out, but the point is this: at some point in your career, certifications should become just one more thing on an excellent resume, rather than the focal point of your resume. Given this, why do I still support certifications? To answer this question, I need to back up into the certification development process a bit.

One of the strangest “mind trips” I’ve ever encountered was working with the “psycho’s” (psychometricians, really, but you know how engineers are with long words) through the entire CCDE/CCAr process. The two things we were challenged constantly were:

  • What does the minimally qualified candidate look like?
  • How do you intend to test for that skill?

Both of these are hard questions.

The first question we turned into a simpler one (again, you know how engineers are): Why do I care? When someone would suggest a particular question or skill, they were immediately met with the counter — Do I care? If I were a designer working on a Continue reading

Fingerprint sensors on their way to more smartphones

Fingerprint authentication will become a lot more common on smartphones of all prices as sensors get cheaper—and Google’s integration of the technology in the next version of Android will make it much easier for app developers and service providers to make use of them.Today, fingerprint sensors are mainly available on high-end models from Apple and Samsung Electronics. But that is about to change, according to sensor manufacturers Synaptics and Fingerprint Cards.Fingerprint Cards has seen a growing interest in its technology from smartphone manufacturers in recent months, as well as a strong increase in orders. As a result, the company has raised its revenue estimate for the year from about 1.5 billion Swedish kronor (US$185 million) to 2.2 billion Swedish kronor.To read this article in full or to leave a comment, please click here

How to generate network packets – Ostinato Packet/Traffic Generator

How does Internet work - We know what is networking

Network Packet Generator or Network Traffic Generator is a tool every network engineer will sooner or later want to use. Here’s one I found and it’s great! First time I saw an Ethernet frame in details on my CCNA class back in 2010 I immediately got the idea about generating some packets on my own. It was logical next step to ask myself: “Ok, so how can I make one of those and see what happens when I send it out on the network?”. I was not really sure that there is a tool that would make it possible. Don’t get me wrong,

Louisiana governor vetoes license plate reader legislation

Louisiana Governor Bobby Jindal has vetoed legislation that would provide for the pilot use of automatic license plate readers by law enforcement to identify stolen vehicles and uninsured motorists.Like GPS trackers on vehicles and so-called Stingrays or “IMSI catchers” that track the location of mobile phones by mimicking cellphone towers, automatic license plate readers have become a controversial privacy issue, with many civil rights groups opposing their indiscriminate use.In a letter, explaining his decision to return the bill to the state Senate, Jindal said the personal information captured by the automatic license plate reader cameras, which includes a person’s vehicle location, would be retained in a central database and accessible to not only law enforcement agencies but also to private entities for a period of time, regardless of whether or not the system detects that a person is in violation of vehicle insurance rules.To read this article in full or to leave a comment, please click here

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
