CCNA R&S Track Changes: Should You Be Worried?

Learning@Cisco recently announced some changes to the CCNA routing & switching track to now include a taste of software defined networking, among other emerging technologies. With some consternation, CCNA candidates are scratching their heads, wondering what, exactly, this new tech means to them. After all, SDN "still does nothing," at least to hear some folks tell the tale. ;-) And yet, here we have Cisco starting to test on this stuff, right down at the associate level of their certification ladder.

Worth Reading: Venezuela and ‘net Neutrality

A recent study conducted by the Institute for Press and Society (IPYS) in Venezuela has confirmed that at least 43 different websites are being blocked in the country, shedding new light on the filtering practices of the Venezuelan government.

Techniques of a Network Detective: A New Series

Put your detective hat on your head and your Network Detective badge on your lapel.  Introducing a new blog series – Techniques of a Network Detective.  This series will focus on the detective work (troubleshooting side) of our jobs as network engineers.

For over 30 years I’ve been playing in the “world of IT”. During those years there have been a lot of changes in our world. But through all that change, there has been a thread, for me, that has always remained constant. A thread and a passion that always seemed to be with me in every job over all these years.

Troubleshooting!

Being a “Network Detective” is much the same as being a regular detective in many ways.  As a Network Detective we get put on a “case” – the “Case of the Missing Packets” maybe.  We go to the crime scene and try to find answers so we can solve the “who done it”

When a “crime” happens you need to be right there interviewing the suspects, surveying the crime scene, asking the right questions.  Trying to quickly figure out what is happening, where it is happening, and why it Continue reading

Cool Tools roundup: Charging, sweating and keyboarding

As part of my research for the Network World Father’s Day 2016 gift idea slideshow, several companies sent along gadgets for me to try out. While some products made the guide, some didn’t – not because they aren’t good, but because I wanted to pick only one device per vendor.  Ventev For example, I chose the Ventev PowerCell 3015+ charger for the guide, but they also sent me some other cool devices. The Desktop Charging Hub (model s500, $50 - See it on Amazon) is a combination device that will help you recharge a phone, a tablet and at least one other USB device. The circular unit also has two 10-amp outlets, for powering additional devices (like your computer, monitor or perhaps other accessories for your desk). The Charging Hub comes with a 5-foot power cord for optimal desktop placement, and two grooves for resting your tablet and/or phone. It should help clean up an area if you do a lot of recharging.To read this article in full or to leave a comment, please click here

Intel’s data center chief talks machine learning — just don’t ask about GPUs

If you want to get under Diane Bryant’s skin these days, just ask her about GPUs. The head of Intel’s powerful data center group was at Computex in Taipei this week, in part to explain how the company's latest Xeon Phi processor is a good fit for machine learning. Machine learning is the process by which companies like Google and Facebook train software to get better at performing AI tasks including computer vision and understanding natural language. It’s key to improving all kinds of online services: Google said recently that it's rethinking everything it does around machine learning.To read this article in full or to leave a comment, please click here

How Intel turned Thunderbolt from a failure into a success

The third time could be the charm for Intel and its Thunderbolt technology. A year after introducing Thunderbolt 3 at Computex 2015, Intel is finally starting to see success with its high-speed external I/O—enough that even doubters might agree it’s winning.You needn’t look far for signs that Thunderbolt 3 will succeed where its two predecessors failed dismally on the PC. This year’s top-tier laptops from HP and Dell, as well models from MSI, Asus, Razer, and Acer, all prominently feature Thunderbolt 3 ports. Almost all of the high-profile laptops of the last few months have prominently featured Thunderbolt 3 ports.To read this article in full or to leave a comment, please click here

Code red: Health IT must fix its security crisis

The health care industry provides an alluring target for malicious hackers. Personal health information has a much longer shelf life than financial information, making it a major draw for identity thieves. But a new and more troubling threat has arisen: the potential disruption of critical hospital systems by cybercriminals.With a diverse array of digital systems, hospitals have evolved into complex technology operations. Yet they remain singularly ill-prepared to defend against attacks, in part because the multiplicity of systems forms a wider surface area to attack.To read this article in full or to leave a comment, please click here

Tricks that ransomware uses to fool you

Pulling ransomware out of …Image by ThinkstockRansomware quite often targets businesses (for example hospitals) rather than individuals. Corporations have more valuable data and more money for ransom (ransom increases from roughly $500 per computer to $15,000 for the entire enterprise). Cyphort has examined different variants of ransomware to help users get an idea of what might be coming down the Internet pipeline. So keep an eye out for these characteristics before your network is taken hostage.To read this article in full or to leave a comment, please click here
