An Introduction to Security and Reliability - What Does It Really Mean?

I co-authored a book in 2005, titled "Extreme Exploits: Advanced Defenses Against Hardcore Hacks." My chapters focused on securing routing protocols such as BGP, and securing systems related to DMZs, firewalls, and network connectivity. As I look back over those chapters, I realize that the basic fundamentals of network security really haven't changed much even though technology has advanced at an incredible pace. "Defense in depth" was a hot catch phrase seven years ago, and it still applies today. more»

Follow a Phishing Case in Real Time: postfinances.com / Swiss Post

It is just another phishing case. Why should I care? I happened to receive my own copy of the phishing email message. Most Internet users will just smile bitterly before deleting it. I checked it to see why it had gone through the spam filters. It had no URL in the text but a reply-to address. So it needed a valid domain name, and had one: postfinances.com. PostFinance (without trailing "s") is the payment system of the Swiss Post. It has millions of users. more»

It's Not Paranoia if They Are Really After You!

In the latest development from the World Conference on International Telecommunications, a new "compromise proposal" has been leaked to wcitleaks.org. This proposal is certainly no compromise, as it not only is a bald faced power grab by the sponsors (Russia, UAE, China, Saudi Arabia, Algeria, Sudan at this point), but shows a stunning lack of comprehension of how the Internet works and how it is currently governed. It also shows that the coalition of Civil Society groups and private sector organisations that have focused on WCIT have been correct all along.  more»

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more»

Ethiopia's Ban on Skype: An Excessive Stretch

Most international Medias picked the story wrong. And I see it being repeated. It is true that there is some legislative initiative regarding the regulation of VoIP calls and mainly the telecommunication sector in Ethiopia. But the initiative is just a draft, noting more. Besides there is no such a thing as 15 years punishment in the draft law for using Skype. Here are the provisions in the draft law that are stretched in many news headlines to bemoan that the use of Skype in Ethiopia entails 15 years punishment. more»

WebRTC/RTCWEB Congestion Control Workshop on July 28 in Vancouver

As we start moving more real-time communications into web browsers with the upcoming WebRTC/RTCWEB offerings, what do we do about congestion control? How do we ensure that all these browser-based communications sessions share the network fairly? With RTC capabilities now already available in builds for browsers such as Google Chrome and Mozilla Firefox, how do we deal with the expected increase in voice, video, chat and data traffic? more»

A Quick Primer on Internet Peering and Settlements

The business world today features many complex global service activities which involve multiple interconnected service providers. Customers normally expect to execute a single paid transaction with one service provider, but many service providers may assist in the delivery of the service. These contributory service providers seek compensation for their efforts from the initial provider. However, within a system of interdependent providers a service provider may undertake both roles of primary and contributory provider, depending on the context of each individual customer transaction. more»

Number Misuse, Telecommunications Regulations and WCIT

Another twenty five years has just zoomed by, and before you know it, it's all on again. The last time the global communications sector did this was at the WATTC in 1988, when "the Internet" was just a relatively obscure experiment in protocol engineering for data communications. At that time the Rather Grand telephone industry bought their respective government representatives... to the Rather Grandly titled "World Administrative Telegraph and Telephone Conference (WATTC) in November 1988 in Melbourne, Australia and resolved to agree to the Rather Grandly titled "International Telecommunication Regulations." more»

Carriers Skirting Rules on Network Neutrality vs. Free's Innovative Network

From will they ever learn department, we are once again seeing attempts by incumbent carriers to skirt rules around network neutrality. They tried and failed with UBB. Now they are at it again with "speed boost" technologies. The two technologies at question are Verizon's "Turbo" service and Roger's "SpeedBoost". more»
