IDG Contributor Network: Yes, Virginia, NFV services can be testable, scalable and predictable

One of the coolest demonstrations at the RSA Conference in San Francisco was of a network functions virtualization (NFV)-based firewall and Deep Content Inspection engine embedded into the software-defined networking (SDN) control plane of a heavily laden network. The firewall/DCI engine filtered content and blocked SQL injection attacks in real time, without slowing down the simulated network. The OpenStack-based testbed was created and run by Spirent, a Southern California firm well known for its network testing platform. The security firm with the firewall and DCI engine was Wedge Networks, a Canadian company that's focused on the cloud.To read this article in full or to leave a comment, please click here

Earthquake rocks Internet in Nepal

dii_nepal

Saturday’s earthquake in Nepal, which claimed the lives of at least 4,000 victims and injured many more, took a toll on the country’s Internet connectivity, which was already one of the least developed in the region.  A recent evaluation of Internet infrastructure in South Asia commissioned by the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) classified Nepal’s international connectivity as ‘weak’ and its fixed and mobile infrastructure as ‘limited’.

While the loss of Internet connectivity pales in comparison to the loss of life, the ability to communicate both domestically and internationally will be crucial in coming days for the coordination of relief efforts already underway.  Innovative services from Facebook and Google to facilitate communicating the status of those affected by the massive earthquake would be largely useless if Nepal had been knocked entirely offline.  In fact, Nepal’s international links generally survived the earthquake, however last mile connectivity is another matter.

As we reported on Saturday, we began seeing severe Internet outages and instabilities immediately following the earthquake at 6:11 UTC.  On the left is a timeline of outages through today and on the right is the volume of DNS queries Continue reading

How does Internet work - We know what is networking

Please note: This has nothing to do with networking in particular! Not if you look from only one perspective. If you look from totally different perspective, with Cisco ACI and all other SDN solutions, you will probably meet with Python programming language (because you will) and then, somewhere in beginning of Python exploration this is the first question that will cross your mind. Of course, if you think like me! Although not directly related to networking, the question bothered me for some time now and the answer is not only really logical when you read it but it is also

Why numbering should start at zero?

The Walls Are On Fire

There’s no denying the fact that firewalls are a necessary part of modern perimeter security. NAT isn’t a security construct. Attackers have the equivalent of megaton nuclear arsenals with access to so many DDoS networks. Security admins have to do everything they can to prevent these problems from happening. But one look at firewall market tells you something is terribly wrong.

Who’s Protecting First?

Take a look at this recent magic polygon from everyone’s favorite analyst firm:

I won’t deny that Checkpoint is on top. That’s mostly due to the fact that they have the biggest install base in enterprises. But I disagree with the rest of this mystical tesseract. How is Palo Alto a leader in the firewall market? I thought their devices were mostly designed around mitigating internal threats? And how is everyone not named Cisco, Palo Alto, or Fortinet regulated to the Niche Players corral?

The issue comes down to purpose. Most firewalls today aren’t packet filters. They aren’t designed to keep the bad guys out of your networks. They are unified threat management systems. That’s a fancy way of saying they have a whole bunch of software built on top Continue reading

How Do I Start My IPv6 Addressing Plan?

One of my readers was reading the Preparing an IPv6 Addressing Plan document on RIPE web site, and found that the document proposes two approaches to IPv6 addressing: encode location in high-order bits and subnet type in low-order bits (the traditional approach) or encode subnet type in high-order bits and location in low-order bits (totally counter intuitive to most networking engineers). His obvious question was: “Is anyone using type-first addressing in production network?”

Decryption tool available for TeslaCrypt ransomware that targets games

Some users whose computers have been infected with a ransomware program called TeslaCrypt might be in luck: security researchers from Cisco Systems have developed a tool to recover their encrypted files.TeslaCrypt appeared earlier this year and masquerades as a variant of the notorious CryptoLocker ransomware. However, its authors seemed intent on targeting gamers in particular.Once installed on a system, the program encrypts files with 185 different extensions, over 50 of which are associated with computer games and related software, including user-generated content like game saves, maps, profiles, replays and mods.To read this article in full or to leave a comment, please click here

Expect more Cyanogen phones from Chinese vendors

Cyanogen, the maker of an Android-based operating system, is hoping it can expand with the help of Chinese handset vendors with global ambitions.The U.S. company has over 50 million users of its CyanogenMod, which is a modified version of Android that can be installed on smartphones manually. But it’s hoping to proliferate the OS even more, by partnering with Chinese companies to release phones that come with the software.“It’s a great way for them to build some identity outside of China using a brand that’s already reasonably well known,” said Kirt McMaster, the company’s CEO.McMaster made the comment Tuesday in Beijing at the Global Mobile Internet Conference. Although the company’s executives declined to name specific vendors, they said the phones would target the international market, and not mainland China, where competition is already heated.To read this article in full or to leave a comment, please click here

First look: Apple’s new MacBook is small, yet completely capable

A few years ago, my first impression of the MacBook Air was generally dismissive -- I felt the Air was underpowered and overpriced -- until I took a second look and realized it was perfect for road warriors. I won't make that mistake twice with Apple's latest MacBook. Like the MacBook Air, the 12-in. MacBook has new design elements that will be a deal-breaker for some and a revelation for others.As of this writing, I've spent less than a week with this laptop -- and the MacBook, with its forward-thinking design and accompanying tradeoffs, is the type of computer that requires time to get a real feel for its strengths and weaknesses. Instead, think of this as more of a first impression; I'll see how these observations hold up when I fully evaluate the MacBook after I've used it more.To read this article in full or to leave a comment, please click here

The Internet of Stupid Things

In those circles where Internet prognostications abound and policy makers flock to hear grand visions of the future, we often hear about the boundless future represented by “The Internet of Things”. In the vision of the Internet of Things we are going to expand the Internet beyond people and press on with connecting up our world using billions of these chattering devices in every aspect of our world. What do we know about the “things” that are already connected to the Internet? Some of them are not very good. In fact some of them are just plain stupid. And this stupidity is toxic, in that their sometimes inadequate models of operation and security can affect others in potentially malicious ways.

Xiaomi tries to end waiting period for phone buyers, amid complaints

Targeting sales of 80 million phones this year, Xiaomi is planning to end “flash sales” of small quantities of its best-selling products.The fast-rising company is China’s largest smartphone vendor, but its devices haven’t always been easy to buy. Xiaomi typically sells limited quantities of its smartphones once a week through its website, forcing customers to often scramble to place orders online.Chinese media have dubbed Xiaomi’s distribution model as a form of “hungry marketing”, that leaves consumers starving for more products. It’s also been the harshest complaint leveled against the company, said Xiaomi president Lin Bin on Tuesday.To read this article in full or to leave a comment, please click here
