Worth Watching: The big four

Worth more than $2.3 trillion combined, the Big Four (Apple, Amazon, Facebook, and Google) continue to grab share from media companies, brands, and retailers. Scott Galloway, Professor of Marketing at the NYU Stern School of Business and Founder of L2, will showcase how the traditional rules of business don’t apply to the Big Four and identify ways that brands and companies can fight back. —Scott Galloway @ YouTube

SHA 2017 – bringing 100 gigabit to the tent

Every 4 years since its start back in 1989, a hacker/security conference takes place in the Netherlands. This summer, the eighth version of this conference, called Still Hacking Anyway 2017 (sha2017.org), will run between the 4th and 8th of August. The conference is not-for-profit and run by volunteers, and this year we’re expecting about 4000 visitors.

For an event like SHA, all the visitors need to connect to a network to access the Internet. A large part of the network is built on Cumulus Linux. In this article, we’ll dive into what the event is and how the network, with equipment sponsored by Cumulus, is being built.

What makes SHA 2017 especially exciting is that it is an outdoor event. All the talks are held in large tents, and they can be watched online through live streams. At the event site, visitors will organize “villages” (a group of tents) where they will work on several projects ranging from security research to developing electronics and building 3D printers.

Attendees will camp on a 40 acre field, but they won’t be off the grid, as wired and wireless networks will keep them connected. The network is designed Continue reading

Women Share Knowledge and Experience in Network Operator Groups in Africa

The Internet Society African Regional Bureau has worked with Network Operator Groups (NOGs) in Africa, providing financial and technical support to organize trainings and events at the local level. We recently shared many of their stories. There are also a number of NOGs that seek to attract women engineers to share knowledge and experience as well as to encourage young women to take up technology-related fields – which are largely perceived in the African region as “men only.” Here are their stories.

Streamline the PCI Assessment Process with a Playbook

Why Create a PCI Assessment Playbook

Having gone through the Payment Card Industry Data Security Standard (PCI DSS) yearly assessment process several times, I can confirm it is a fairly intensive assessment that will require a large effort from a lot people!

Each assessment the Assessors will request evidence, review documentation, ask for sample system configurations, be onsite to interview and observe personnel, and present observations or findings that must be remediated. These various assessment activities and last-minute remediation efforts can be very disruptive to all involved, and usually result in “fire drill” activities that require personnel to be pulled away from their daily tasks to react to the assessment requests.

Since the PCI assessment is very similar from year to year, and with some well thought out planning it is possible to streamline the assessment process. Just like in football, having a well thought out strategy in the form of a playbook can assist everyone that needs to know their part, or what needs to be done when. With this cylinder process in place and in the form of a PCI Assessment Playbook that everyone can follow, it can greatly reduce the stress historically associated with the assessment and attaining Continue reading

Worth Reading: Google rewires the Internet

When all of your business is driven by end users coming to use your applications over the Internet, the network is arguably the most critical part of the infrastructure. That is why search engine and ad serving giant Google, which has expanded out to media serving, hosted enterprise applications, and cloud computing, has put a tremendous amount of investment into creating its own network stack. —Timothy Prickett Morgan @ The Next Platform

It’s Probably Not The Wi-Fi

After finishing up Mobility Field Day last week, I got a chance to reflect on a lot of the information that was shared with the delegates. Much of the work in wireless now is focused on analytics. Companies like Cape Networks and Nyansa are trying to provide a holistic look at every part of the network infrastructure to help professionals figure out why their might be issues occurring for users. And over and over again, the resound cry that I heard was “It’s Not The Wi-Fi”

Building A Better Access Layer

Most of wireless is focused on the design of the physical layer. If you talk to any professional and ask them to show your their tool kit, they will likely pull out a whole array of mobile testing devices, USB network adapters, and diagramming software that would make AutoCAD jealous. All of these tools focus on the most important part of the equation for wireless professionals – the air. When the physical radio spectrum isn’t working users will complain about it. Wireless pros leap into action with their tools to figure out where the fault is. Either that, or they are very focused on providing the right design from Continue reading

Settlement-Free Peering Requirements

Settlement-Free Peering Requirements.   I explained the Peering , Types of Peering basics in one of the previous posts. When we talk about peering, we generally mean settlement-free peering. But what are the common requirements for companies to peer with each other ?   Settlement-free peering is called as Internet Peering as well.   So, companies setup […]
