Free Webinar: Introduction to SDN

Almost exactly two years ago I ran an Introduction to SDN webinar trying to explain what SDN might be. The landscape has changed significantly in the meantime (for example, software/hardware disaggregation is becoming a reality), but SDN remains as meaningless as Cloud and wrapped in many layers of marketing nonsense.

It was clearly time to do a second version of the webinar, and it’s still free thanks to my sponsor NIL Data Communications. All you have to do to attend it is to fill in the registration form.

BGP in 2015

The Border Gateway Protocol, or BGP, has been holding the Internet together, for more than two decades and nothing seems to be falling off the edge so far. But the past does not necessarily determine the future. How well is BGP coping with the ever-growing Internet?

OpenSSL patches a severe but not widespread problem

The OpenSSL project has patched a problem in the cryptographic library but one that likely does not affect many popular applications.OpenSSL enables SSL (Secure Sockets Layer) or TLS (Transport Layer Security) encryption. Most websites use it, which is indicated in Web browsers with a padlock symbol.It's an open-source library that is widely used in applications for secure data transfers. After serious vulnerabilities were found in OpenSSL over the last couple of years, the application has been under much scrutiny by security researchers.MORE ON NETWORK WORLD: 6 simple tricks for protecting your passwords The latest vulnerability affects versions 1.0.1 and 1.0.2.

Using GITHub to build our Network Configs

As I wrote in this post, one of my goals for this year is to be able to compltely automate the build of my lab environment programatically.

In the last couple of jinja posts, I wrote about the basics of Jinja2 templates and how they can be applied to building network configurations.

In this post, I’m going to take the next step and move those files from my local hard drive out to…

Asentinel reduces costs and improves the efficiency of mobile device service contracts  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  If I brought up the term "mobility management" you'd probably think I was talking about BYOD and managing how workers can securely access applications and data via their smart phones. That's the aspect of mobility that IT usually has to deal with. But there's also an administrative aspect to mobility management that can be a real pain – and a big expense – for companies if it's not done well.I'm referring to the contract management aspect of company-provided mobile devices. Companies that pay for their employees' device contracts through expense reports are missing an opportunity to reduce administrative hassles and save quite a bit of money.To read this article in full or to leave a comment, please click here

Data destruction 101: There’s more to it than wiping your drive [Infographic]

In 2009, a team of journalists who were investigating the electronic waste, purchased a computer in a Ghana market that was found to contain "sensitive documents belonging to U.S. government contractor Northrop Grumman," wrote Robert McMillan in a story at the time. "Northrop Grumman is not sure how the drive ended up in a Ghana market, but apparently the company had hired an outside vendor to dispose of the PC."That's a nightmare scenario, to be sure.And in the years since, businesses have continued to store vast quantities of data on servers, hard drives, and media storage devices — sensitive data that should be protected or destroyed. But the options for data destruction can be overwhelming.To read this article in full or to leave a comment, please click here(Insider Story)

U.S. carriers stay tight-lipped on LTE-U deployments

America’s big four wireless service providers are enthusiastic about the prospect of delivering data over unlicensed frequencies via LTE-U, but they’re playing their cards very close to their chests when it comes to specific plans.LTE-U, which is a wireless protocol designed to let carriers use their LTE signals over the same unlicensed frequencies as Wi-Fi, is a controversial technology. Advocates, which include the wireless carriers, insist that coexistence features built into the standard will allow it to use the same airwaves as Wi-Fi without interference. Critics say that independent testing shows that LTE-U could drown out Wi-Fi signals when the two conflict.To read this article in full or to leave a comment, please click here
