Silver Peak enhances its SD-WAN edge device to improve the branch experience  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  If you want to get a sense for how rapidly the SD-WAN market is evolving, go back and read some of the articles from, say, two years ago. Some of the talk was about startup companies entering the market, while other items describe how traditional WAN hardware vendors were pivoting to get into the lucrative new market of building network functions in software.Predictions of the eventual market size varied back then, but everyone knew it would be big. Doyle Research thought it might get to $3.2 billion by 2018. IDC projected a $6 billion market by 2020. I wouldn’t be surprised if those estimates from a few years ago turn out to be too conservative.To read this article in full or to leave a comment, please click here

Worth Reading: Criminals getting closer to state actors

A few years ago, we saw a clear difference between state actors and criminals looking at the technologies and procedures they applied attacking an environment. Over time we have seen these two groups coming closer together. In the meantime, criminals seem to have caught up. They started to use more sophisticated and targeted malware and they do not shy away from calling their victims and helping them to run “the macro in the Word document”… —Halbheer on Security

5G wireless behind AT&T, Verizon’s big buys

5G technology, despite some fairly breathless hype, is still in the embryonic stages of development, but the pace is quickening. The major U.S. carriers are racing to buy up critical spectrum that will be necessary for the realization of 5G’s potential, which could include support for speeds up to 1Gbps and support for the ever-expanding Internet of Things.AT&T has made two major purchases with that end in mind – January saw the company announce the acquisition, for an undisclosed sum, of bankrupt wireless backhaul provider FiberTower, and just this week AT&T said that it would spend about $1.6 billion in an all-stock deal to acquire Straight Path Communications (Note: A Reuters report overnight cited sources as saying Verizon might try to top AT&T’s bid).To read this article in full or to leave a comment, please click here

Understanding Our Cache and the Web Cache Deception Attack

About a month ago, security researcher Omer Gil published the details of an attack that he calls the Web Cache Deception attack. It works against sites that sit behind a reverse proxy (like Cloudflare) and are misconfigured in a particular way. Unfortunately, the definition of "misconfigured" for the purposes of this attack changes depending on how the cache works. In this post, we're going to explain the attack and then describe the algorithm that our cache uses to decide whether or not to cache a given piece of content so that customers can be sure that they are secure against this attack.

The Attack

First, we'll explain the basics of the Web Cache Deception attack. For those who want a more in-depth explanation, Omer's original post is a great resource.

How will future cars stay up-to-date? Make them open like a PC

The future seems bright for the automobile. A whole host of technologies -- including self-driving systems – is set to reinvent the auto industry, making cars more computerized than ever.But not everyone shares a rosy outlook.  “I know what is going to happen in the future and I don’t like it,” said Bruce Perens, a leading open source advocate.  “And I would like to guide it in a somewhat different direction.”His fear is that consumers who buy next-generation cars will face obstacles to modifying or repairing them -- like purchasing a smartphone, only far more expensive, with manufacturers in sole control over the tech upgrades.To read this article in full or to leave a comment, please click here

Understand more, fear less: How the future of the Internet can be designed with a human face

Last week, the G20’s ministers responsible for the digital economy met in Düsseldorf to prepare this year´s G20 summit, scheduled for Hamburg, July 2017.
