Every year those in the security industry are bombarded with various cyber security predictions. There's the good, the bad and the ugly. Some predictions are fairly ground breaking, while others are just recycled from previous years -- that's allowed of course if the threats still stand. In part one of my predictions I looked at the malware threats, so let's take a look at big data and the cloud for part two. more
As a follow up to the earlier article on the IaaS business model, here is a high level overview of the SaaS provider business model and some of the strategic options that are in there... As examples in this article I consider two hypothetical SaaS providers. The first one delivers bookkeeping software, the second one delivers a project collaboration platform. more
The promise of "big data" -- real-time insights, predictive analytics and a better understanding of customer behaviors -- has many companies jumping into this near-bottomless information pool with both feet. But the sheer volume of data can cause serious stress for IT professionals trying to balance C-suite expectations, legacy tech limitations and corporate workloads. What's more, the data market is rapidly evolving. more
The Internet Society (ISOC) has been working with the African Union (AU) to facilitate the African Internet Exchange System (AXIS). This AXIS project funded by the EU-Africa Infrastructure Trust Fund and the Government of Luxembourg will help keep Internet traffic in Africa internal to the continent and avoid expensive international transit costs and delay latency in routing Internet traffic through other continents. more
In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more
The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? more
Nowadays, everybody is talking about cloud computing. Fans say it's the future, the answer to every problem with computing as we know it; others say it's just a fad and will eventually die. Who's right? While nobody knows the future, the fact is, enough evidence is available that we can all reasonably predict what's coming. Consider these facts... more
BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more
When I read government arguments in defense of the NSA, an oft-repeated line was: We're not targeting Americans. We're targeting foreigners. Foreigners. I really dislike that word. And I'm sure companies like Apple, Google and Facebook do as well. Why? more
2013 may be a promising year for global trade in technology with the kick-off of the International Technology Agreement expansion discussions, the Trans-Atlantic Trade and Investment Partnership, and as the Trade in Services Agreement gets going. But China calls its own tune, and is now threatening to restrict its market for Internet-enabled technologies through a clever device that could cost its trading partners billions. more
