Apple’s Tim Cook woos app developers in India

In a bid to win over more Indian developers, Apple on Wednesday announced it would set up by early next year a facility to help developers on best practices and to improve the design, quality and performance of their apps on the iOS platform.The facility in Bangalore, called a Design and Development Accelerator, aims to provide specialized support for the “tens of thousands” of developers in the country, who develop applications for the iOS operating system.Bangalore has a large base of developers, working for the research and development centers of multinational companies or in startups, besides others who work independently. Apple estimates that over 1 million people in the city work in the tech sector, with over 40 percent of graduates from local universities specializing in engineering or IT.To read this article in full or to leave a comment, please click here

Fragmenting IPv6

The design of IPv6 represented a relatively conservative evolutionary step of the Internet protocol. Mostly, it's just IPv4 with significantly larger address fields. Mostly, but not completely, as there were some changes. IPv6 changed the boot process to use auto-configuration and multicast to perform functions that were performed by ARP and DHCP in IPv4. IPv6 added a 20-bit Flow Identifier to the packet header. IPv6 replaced IP header options with an optional chain of extension headers. IPv6 also changed the behaviour of packet fragmentation. Which is what we will look at here.

CCDE – I passed the CCDE Practical in Madrid!

Hi everyone.

I’ve not been posting lately because I have been studying very hard for the CCDE practical.

Passed the lab in Madrid? Isn’t this guy from the North? I was supposed to take this exam in Frankfurt on Tuesday the 17th of May. Wise from my trips to the CCIE lab in Brussels I took a flight that landed around noon on Monday. I have a routine I like to use the day before a big exam. I had just scouted the Pearson Professional Centre (PPC) location and got back to my room. At 14.05 I receive an e-mail from Pearson Vue saying they can’t deliver my exam. Can you imagine the panic I felt? I had been preparing for months of furious studying for this day. The CCDE practical is only delivered every three months so I would have to wait for three more months to take it if I could even get a seat then. I had prepared for this day and my plan was to try to pass it and if I didn’t, come back in three months and pass it then.

There was no time to waste. I found an open seat in Madrid Continue reading

Black hole detection

The Broadcom white paper, Black Hole Detection by BroadView™ Instrumentation Software, describes the challenge of detecting and isolating packet loss caused by inconsistent routing in leaf-spine fabrics. The diagram from the paper provides an example, packets from host H11 to H22 are being forwarded by ToR1 via Spine1 to ToR2 even though the route to H22 has been withdrawn from ToR2. Since ToR2 doesn't have a route to the host, it sends the packet back up to Spine 2, which will send the packet back to ToR2, causing the packet to bounce back and forth until the IP time to live (TTL) expires.

The white paper discusses how Broadcom ASICs can be programmed to detect blackholes based on packet paths, i.e. packets arriving at a ToR switch from a Spine switch should never be forwarded to another Spine switch.

This article will discuss how the industry standard sFlow instrumentation (also included in Broadcom based switches) can be used to provide fabric wide detection of black holes.

The diagram shows a simple test network built using Cumulus VX virtual machines to emulate a four switch leaf-spine fabric like the one described in the Broadcom white paper (this network is Continue reading

IDG Contributor Network: Paper to be an IoT-connected device

Regular paper, of the kind one writes and prints on, can be embedded with radio frequency tags, researchers say. That could ultimately allow internet connectivity.Not only could the internet paper be manufactured with tags added at the mill, but an end user could actually draw the tagged antennas on by hand using conductive ink in a school or the workplace.By responding to commands via gestures, the paper can be made to “do anything from controlling music using a paper baton to live polling in a classroom,” the University of Washington says in a press release.To read this article in full or to leave a comment, please click here

Worth Reading: Lego Robots versus Gesture Security

A DARPA-funded report titled “Robotic Robbery on the Touch Screen” published recently in the journal ACM Transactions on Information and System Security looks at gestural authentication through the eyes of a more sophisticated hacker. It presents two Lego-driven robotic attacks on a touch-based authentication system—one is based on gestural statistics collected over time from a large population of users and the other is based on stealing gestural data directly from a user. Both were pretty effective. -via Motherboard

Microsoft is joining the tech cry for Britain to stay in the EU

Microsoft has come out against a proposal for the U.K. to leave the European Union, joining other tech giants that oppose the controversial measure.The so-called Brexit (Britain exit) referendum will ask U.K. voters on June 23 whether the country should leave the 28-state EU. Proponents say membership in the union has hurt Britain’s economy and opens the country up to too much immigration.Boris Johnson, London’s colorful former mayor, has compared the EU to Hitler. Polls suggest the vote may be tight.IBM, Cisco Systems, and Hewlett Packard Enterprise also oppose Brexit. As multinational companies, they often rely on flows of capital and employees across borders.To read this article in full or to leave a comment, please click here

Thinking about side channel attacks

When Cyrus wanted to capture Babylon, he attacked the river that flows through the city, drying it out and then sending his army under the walls through the river entrance and exit points. In a similar way, the ventilator is a movie favorite, used in both Lord of the Rings and Star Wars, probably along with a thousand other movies and stories throughout time. What do rivers and ventilators have to do with network security?

Side channel attacks. Now I don’t know if the attacks described in these papers, or Cyrus’ attack through the Euphrates, are considered side channel, or just lateral, but either way: the most vulnerable point in your network is just where you assume you can’t be attacked, or that point where you haven’t thought through security. Two things I read this week reminded me of the importance of system level thinking when it comes to security.

The first explores the Network Time Protocol (NTP), beginning with the general security of the protocol. Security in a time protocol is particularly difficult, as the entire point of encryption is to use algorithms that take a lot of time for an attacker to calculate—and there’s probably some relationship between Continue reading

FCC’s ‘relentless regulatory assault’ threatens cable industry

BOSTON -- The head of the leading cable trade group feels like the federal government is trying to pick winners and losers.Michael Powell, president and CEO of NCTA, the organization representing firms like Comcast and Cox in Washington, argues that federal regulators have been pursuing policies that would create a two-tier regulatory regime that favors Internet firms over the telecom providers that deliver broadband and cable access services."What I believe is most troubling is an emerging government view that the communication market is bifurcated and should be regulated differently -- Internet companies are nurtured and allowed to run free, but network providers are disparagingly labeled 'gatekeepers' that should be shackled," Powell said in a keynote address at NCTA's annual Internet and TV conference. "The implications of this world view go far beyond how it affects one industry."To read this article in full or to leave a comment, please click here
