Stealth Falcon group uses custom spyware, fake journalists to target UAE dissidents

Meet Stealth Falcon, a sophisticated and likely state-sponsored cyberespionage group, which is hell bent on conducting targeted spyware attacks “against Emriati journalists, activists and dissidents.” The digital attacks started in 2012 and are still being carried out against United Arab Emirates (UAE) dissidents. It’s not “just” spying with custom spyware that leads to dissidents being “arbitrarily detained;” once identified as criticizing the authorities, UAE dissidents can be forcibly disappeared.“The UAE has gotten much more sophisticated since we first caught them using Hacking Team software in 2012,” Bill Marczak, a senior researcher at Citizen Lab told the New York Times. “They've clearly upped their game. They're not on the level of the United States or the Russians, but they're clearly moving up the chain.”To read this article in full or to leave a comment, please click here

Move over Skylake: An Asus PC with Intel’s Kaby Lake chip is coming in Q3

The wait for Intel's Kaby Lake chip will end in the third quarter this year, as the first PC with the 7th Generation Core chip was announced at Computex. Kaby Lake, the successor to Intel's Skylake Core processor chips, will be in the Asus Transformer 3 tablet. The device is much like Microsoft's Surface Pro 4, and will ship in the third quarter starting at US$799, according to a blog entry on Microsoft's website. The Transformer 3 was among a gaggle of PC and phone products announced by Asus at Computex. No other Kaby Lake PC has been announced yet, but expect Lenovo, HP, Dell and others to follow suit.To read this article in full or to leave a comment, please click here

Nvidia chief downplays challenge from Google’s AI chip

Nvidia has staked a big chunk of its future on supplying powerful graphics chips used for artificial intelligence, so it wasn't a great day for the company when Google announced two weeks ago that it had built its own AI chip for use in its data centers.Google's Tensor Processing Unit, or TPU, was built specifically for deep learning, a branch of AI through which software trains itself to get better at deciphering the world around it, so it can recognize objects or understand spoken language, for example.To read this article in full or to leave a comment, please click here

Strain relief

I’ve got a problem with sagging cables, and I’ve got a simple solution. Examine the side-by-side images below which show the same fiber connection between a switch and a firewall. The image on the left shows a sagging cable which crosses in front of the switch in the rack unit just below it.
As you may know, this cabling install is a violation of the 167th rule of networking:

Thou shalt contain your cables to your own rack unit and shalt not, under any circumstances, impede access to other rack units or blades.


SnipImageThe image on the right ticks the box for me. There’s no room for a dedicated 1RU horizontal cable manager, but there is room for a zero-RU strain relief bar (as seen below). The result is a relatively neat cabling job. It’s no work of art, but it’s functional.
strain relief barA strain-relief bar is a cheap metal bar that you can bolt on when you rack-mount your switch. It allows you to velcro your fiber patches to the bar, taking the strain to help prevent breaks and preventing the dreaded cable droop. You should, of course, take care to ensure you don’t block access to any field-replaceable units, cards or ports on your network device.
The strain-relief bar Continue reading

Building a L2 Fabric on top of VXLAN: Arista or Cisco?

One of my readers working as an enterprise data center architect sent me this question:

I've just finished a one-week POC with Arista. For fabric provisioning and automation, we were introduced to CloudVision. My impression is that there are still a lot of manual processes when using CloudVision.

Arista initially focused on DIY people and those people loved the tools Arista EOS gave them: Linux on the box, programmability, APIs… However

Iran orders messaging apps to store data of local users in the country

Iran has ordered foreign messaging apps to transfer data and activity records of Iranian users to local servers within a year, a move that will give the country a greater ability to monitor and censor the online activity of its people.The country’s Supreme Council of Cyberspace has issued instructions to foreign messaging companies active in the country, requiring them “to transfer all data and activity linked to Iranian citizens into the country in order to ensure their continued activity," news reports said quoting state-run media.Social media platforms such as Twitter and Facebook are already blocked in the country whose government holds a tight control over Internet access by its people.To read this article in full or to leave a comment, please click here

Microsoft CEO Satya Nadella follows Apple’s Tim Cook to India

Microsoft’s CEO Satya Nadella is visiting India, reflecting the growing importance of the country as a market for multinational technology companies. Nadella’s visit follows the first trip to India by Apple CEO Tim Cook, who visited the country this month to drum up support for the company’s plans to offer refurbished iPhones in the price-sensitive market as well as to get permission to set up its wholly-owned stores in the country. Both deals appear to have been blocked by regulators, according to reports. While Apple was largely seen as lacking focus on India until recently, when its China revenue fell 11 percent, while iPhone sales in India grew 56 percent year-on-year in the last quarter, Microsoft has been a long-time player in the Indian market.To read this article in full or to leave a comment, please click here

31 – Multiple approaches interconnecting VXLAN Fabrics

As discussed in previous articles, VXLAN data plane encapsulation in conjunction with its control plane MP-BGP AF EVPN is becoming the foremost technology to support the modern network Fabric.

It is therefore interesting to clarify how to interconnect multiple VXLAN/EVPN fabrics geographically dispersed across different locations.

Three approaches can be considered:

 The 1st option is the extension of multiple sites as one large single stretched VXLAN Fabric. There is no network overlay boundary per se, nor VLAN hand-off at the interconnection, which simplifies operations. This option is also known as geographically dispersed VXLAN Multiple PoD. However we should not consider this solution as a DCI solution as there is no demarcation, nor separation between locations. Nonetheless this one is very interesting for its simplicity and flexibility. Consequently we have deeply tested and validated this design.

  • The second option to consider is multiple VXLAN/EVPN-based Fabrics interconnected using a DCI Layer 2 and layer 3 extension. Each greenfield DC located on different site is deployed as an independent fabric, increasing autonomy of each site and enforce global resiliency. This is often called Multisite. A Data Center Interconnect technology (OTV, VPLS, PBB-EVPN, or even VXLAN/EVPN) is therefore used to extend Layer 2 and Layer Continue reading
