DNS OARC 24

For a supposedly simply query response protocol that maps names to IP addresses there a huge amount going on under the hood with the DNS. DNS OARC held a 2 day workshop in Buenos Aires prior to IETF 95. Here are my impressions of this meeting.

Intel’s top PC, IoT executives leave in management shakeup

The writing was on the wall for some Intel executives after a former Qualcomm executive was hired to oversee the company's PC, Internet of Things and software businesses, and two of them are departing.Kirk Skaugen, who previously led the Client Computing Group, and Doug Davis, who ran the IoT group, are leaving the company, Intel said Monday.Their roles were diminished after the November appointment of Venkata Renduchintala, who formerly worked at Qualcomm, as president of Intel's Client and IoT businesses and its Systems Architecture Group. Renduchintala, who's known as Murthy, is effectively Intel's number two executive after Brian Krzanich.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Light will ultimately secure the Internet, scientists say

The Internet will eventually be secured from hackers by a technology called quantum photonics, say researchers. Single light particles will ultimately be used to exchange information in secure systems, they think. The technique is part of quantum computing. And now that a limitation has been overcome, the scientists at the University of Sydney say that the ultra-secure system is one step closer to realization. It’s been guessed at that photonics will be the future of security, however figuring out how to create a single photon has been holding back the forward movement in the research, the team says in a news release on the university’s website. They now think they’ve figured out how to do it.To read this article in full or to leave a comment, please click here

Brocade buying Ruckus Wireless for $1.2 billion

Networking hardware vendor Brocade announced today that it would add a wireless infrastructure club to its bag in the form of Ruckus Wireless, as part of a deal with a net value of $1.2 billion.The objective, according to Brocade’s public statement, is to broaden the company’s enterprise networking stable and boost profits, since wireless is a growth area. Like any merger of this type, the idea seems to be to offer a unitary set of products and services.+ALSO ON NETWORK WORLD: HTTP compression continues to put encrypted communications at risk + 12 powerful Windows 10 tools that hardcore PC enthusiasts will loveTo read this article in full or to leave a comment, please click here

Researchers reveal ‘Surreptitious Sharing on Android’ vulnerabilities

TU Braunschweig, Institute for Operating Systems and Computer Networks, Professors Dominik Schürmann and Lars Wolf are warning about a “Surreptitious Sharing” vulnerability which is present in many Android communication apps. Their pre-published research paper, Surreptitious Sharing on Android (pdf), is to be presented at the security conference GI Sicherheit 2016.To read this article in full or to leave a comment, please click here

Securing BGP: A Case Study (6)

In my last post on securing BGP, I said—

Here I’m going to discuss the problem of a centralized versus distributed database to carry the information needed to secure BGP. There are actually, again, two elements to this problem—a set of pure technical issues, and a set of more business related problems. The technical problems revolve around the CAP theorem, which is something that wants to be discussed in a separate post; I’ll do something on CAP in a separate post next week and link it back to this series.

The CAP theorem post referenced above is here.

securing-bgpBefore I dive into the technical issues, I want to return to the business issues for a moment. In a call this week on the topic of BGP security, someone pointed out that there is no difference between an advertisement in BGP asserting some piece of information (reachability or connectivity, take your pick), and an advertisements outside BGP asserting this same bit of information. The point of the question is this: if I can’t trust you to advertise the right thing in one setting, then why should I trust you to advertise the right thing in another? More specifically, if you’re using Continue reading

HTTP compression continues to put encrypted communications at risk

Security researchers have expanded and improved a three-year-old attack that exploits the compression mechanism used to speed up browsing in order to recover sensitive information from encrypted Web traffic.The attack, known as BREACH, takes advantage of the gzip/DEFLATE algorithm used by many Web servers to reduce latency when responding to HTTP requests. This compression mechanism leaks information about encrypted connections and allows man-in-the-middle attackers to recover authentication cookies and other sensitive information.The BREACH (Browser Reconnaissance and Exfiltration via Adaptive Compression of Hypertext) attack was first presented at the Black Hat USA security conference in August 2013 by security researchers Angelo Prado, Neal Harris and Yoel Gluck. While it theoretically affects all SSL/TLS ciphers, their version of the attack was most effective against connections encrypted with stream ciphers, such as RC4.To read this article in full or to leave a comment, please click here

The Network of 2020, what should CxOs expect?

Being an analyst I’m often asked to look ahead and predict what markets will look like in three to five years. Recently, I’ve been asked that if I were to design a next-generation network, which would be fully operational by 2020, what would it look like? The network industry has gone through more change in the past two years than it had gone through in the previous two decades so a network in 2020 will look significantly different than the networks of today.Predicting the future is obviously challenging but sometimes it’s better to look back to understand what the future will look like. In networking, there are many lessons we can learn from the last 20+ years where networks have evolved to be able to meet ongoing application and business needs. The innovation was obviously necessary but each time something new was bolted on to the network, there was a price to be paid. For example, WiFi being deployed as an overlay means having to manage two separate networks. Below are the top lessons learned from legacy networks over the past two decades.To read this article in full or to leave a comment, please click here

Most powerful Internet of Things companies

Billions of devices, lots of opportunityThe Internet of Things (IoT) is still nascent, but growing quickly. Research firm IDC predicts it will become a $1.46 trillion international market by 2020, up from $700 billion last year. A trillion-dollar market means a lot of companies will want a slice. So who are the leaders of the IoT? We consulted with some of the leading analysts to find out. (Note: Companies are listed in alphabetical order.)

Broken Configurations, Broken Windows

The “broken windows” theory states that small problems can become bigger ones unless dealt with quickly. The theory suggests that people infer the rules of behavior from what they observe. It suggests that working hard to clean up a neighborhood by making repairs like fixing broken windows will help to deter further vandalism. In this article, I will discuss how this theory applies to network configuration. -via Network Computing
