In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more
A report "Securing Cyberspace for the 44th Presidency" has just been released. While I don't agree with everything it says (and in fact I strongly disagree with some parts of it), I regard it as required reading for anyone interested in cybersecurity and public policy. The analysis of the threat environment is, in my opinion, superb; I don't think I've seen it explicated better. Briefly, the US is facing threats at all levels, from individual cybercriminals to actions perpetrated by nation-states. The report pulls no punches... more
An acquaintance asked whether there's been any progress in the oft-rumored project to come up with a more secure replacement for SMTP. Answer: No. Truly, spam isn't a technical problem, it's a social one. If we could figure out some way to make mail recipient networks and hosts willing to shun known bad actors, even at the cost of losing some real mail for a while until the bad actors cave, it would make vastly more difference than any possible technical changes. more
North American p2p went from 370 petabytes in 2006 to only 416 petabytes in 2007 according to Cisco's figures. Since U.S. users increased 16% in the same period, that's a drop in p2p per user and a significant drop in p2p as a percentage of all traffic. There's a major margin of error in these figures, so I'm calling it "flat." That's very different from pre 2007 experience, when p2p grew rapidly. It severely contradicts what many in Washington D.C. are saying... more
"The world is flattening," says Dave Rubal at the FOSE Conference and Exhibition this week in Washington, DC. "The race for IT dominance is on, and it is coming west." Mr. Rubal, Cisco's Worldwide Internet Protocol version 6 (IPv6) Task Force Lead, spoke of the tremendous race in IT dominance that is occurring, stating that the "mainstay technologies at the Beijing Olympics will be IPv6-powered." IPv6 is in line to replace version 4, but Rubal hinted that China and other Far East countries may be adopting the new version faster than the United States... more
The Internet Architecture Board's (IAB) chair, Olaf Kolkman, asked the members of the IAB to provide a statement paper each on what they believe the current most pressing issues in terms of Internet architecture are... I have thought about this for the past few days, and realised that it's hard to come up with overarching issues and even harder to come up with issues, where the IAB actually could make a difference. But I came with up with two issues. more
In this article we'd like to look at some measures of the use of IPv4 and IPv6 protocols in today's Internet and see if we can draw any conclusions about just how far down the track we are with the IPv6 part of dual stack deployment. We'll use a number of measurements that have been made consistently since 1 January 2004 to the present, where we can distinguish between the relative levels of IPv4 and IPv6 use in various ways. more
At the Emerging Communications Conference eComm 2008, I'm moderating a panel "Wireless Innovation, with or without operators." This will be a discussion -- smart people from differing camps responding to (hopefully) probing questions from yours truly, and the audience. Points of view represented include Google Android, J2ME/JavaFX Mobile, iPhoneWebDev.com, Skype and Trolltech Qtopia (Nokia), plus Chris Sacca, formerly head of Google's wireless initiatives. I've been thinking about subjects and questions for the panel. As a start, I'll set down my current views, then seek others' views and questions. more
Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more
Telco front-man Scott Cleland, in a recent blog post, thumbs his nose at the Four Internet Freedoms and says that the FCC should too. Under current leadership, it probably will. Referring to the recent submissions to the FCC by Free Press and Public Knowledge and Vuze complaining about Comcast's use of reset packets to block applications that compete with Comcast's own proprietary video entertainment offering, Cleland says "Network management trumps net neutrality." There are lots of reasons for, ahem, managing. Cleland neglects to observe that controlling congestion the way Comcast does it is like scattering nails in the road for traffic control. more
There has recently been some good and bad news about WiMAX. On the good news part, an announcement made by the WiMAX Forum this month regarding the launching of the Mobile WiMAX certification program through which vendors can get their IEEE 802.16e-2005 equipment tested and possibly certified... On the bad news part, there was the Sprint-Clearwire breakup after three months of announcing a plan to join forces in building a nationwide WiMAX network in the US. Although it is anticipated that each company would carry on with its own WiMAX plans, analysts believe that the breakup would have negative impact on WiMAX deployment in the US... more
There are discussions starting within the Regional Internet Registries (RIRs) about the creation of trading market in IPv4 addresses as we approach the inevitable exhaustion of unallocated addresses. The view being put forward is basically "this is likely to happen anyway and by discussing it now, we can ensure it happens in an orderly way". When I first heard this idea I was a bit surprised. The RIRs are policy based bodies and so a shift to a trading market appears to be an abandonment of that policy base. However I have been partly corrected on that. more
Back in the late 1990s I was often asked what I thought would happen if Internet bandwidth was infinite -- what would that change about the Internet itself? Level 3's (LVLT) recent decision to slash prices on its content distribution network and rumors of new multi-terabit cables across the Pacific have me wondering if we are actually getting closer to having infinite bandwidth. But when replying to the infinite bandwidth question I was prone to posing a return question -- what does infinite bandwidth actually mean? more
There have been lots of press stories in the last day reporting on what the Internet shutdown in Myanmar looked like for people there, and that's the important story. This is what it looked like to the rest of the world, from an Internet infrastructure standpoint. The connection between Myanmar and the rest of the world appears to be turned back on, at least temporarily. The 45 megabit per second circuit connecting Myanmar to Kuala Lumpur that is Myanmar's primary connection to the Internet came back up at 14:27 UTC today. It had mostly been "hard down," indicating either that it had been unplugged or that the router it was connected to was turned off, with the exception of a few brief periods since September 28. Myanmar's country code top level domain, .MM, disappeared... more
A deal announced today between British Telecom and upstart FON allows BT's Internet customers to share their own broadband connections via WiFi and, in turn, be able to access WiFi free at "thousands" (doesn't say how many) of FON hotspots around the world operated by other Foneros... When you buy home Internet access from BT and opt into this plan, you are also buying roaming access at no extra charge. The technology is supposed to assure that the part of the connection which you share is segregated from your own access so that there are no security problems caused by the sharing. more
