Worth Reading: Security Orchestration and Incident Response

Last month at the RSA Conference, I saw a lot of companies selling security incident response automation. Their promise was to replace people with computers ­– sometimes with the addition of machine learning or other artificial intelligence techniques ­– and to respond to attacks at computer speeds. While this is a laudable goal, there’s a fundamental problem with doing this in the short term. You can only automate what you’re certain about, and there is still an enormous amount of uncertainty in cybersecurity. Automation has its place in incident response, but the focus needs to be on making the people effective, not on replacing them ­ security orchestration, not automation. —Schneier on Security

4 reasons Cisco’s IoT forecast is right, and 2 why it’s wrong

Peter Corcoran, Ph.D., who describes himself as long-term IoT skeptic, published a research paper recently on arXiv.org—Third time is the charm – Why the World just might be ready for the Internet of Things this time around (pdf)—in which he speculates that this incarnation of the Internet of Things (IoT) may succeed.Technologies often fail on introduction, later to reemerge and become widely adopted. The PC, smartphone and tablet all went through at least one of these cycles.RELATED: IoT catches on in New England fishing town In the early 1990s, the Consumer Electronics Association first tried to promote CEBus, a specification for interconnecting devices in the home that supported multiple physical layers, including twisted pair, coaxial cable, powerline, wireless and even RF. CEBus was too early.To read this article in full or to leave a comment, please click here

Critical Xen hypervisor flaw endangers virtualized environments

A critical vulnerability in the widely used Xen hypervisor allows attackers to break out of a guest operating system running inside a virtual machine and access the host system's entire memory.This is a serious violation of the security barrier enforced by the hypervisor and poses a particular threat to multi-tenant data centers where the customers' virtualized servers share the same underlying hardware.The open-source Xen hypervisor is used by cloud computing providers and virtual private server hosting companies, as well as by security-oriented operating systems like Qubes OS.The new vulnerability affects Xen 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x and has existed in the Xen code base for over four years. It was unintentionally introduced in December 2012 as part of a fix for a different issue.To read this article in full or to leave a comment, please click here

Google says its AI chips smoke CPUs, GPUs in performance tests

Four years ago, Google was faced with a conundrum: if all its users hit its voice recognition services for three minutes a day, the company would need to double the number of data centers just to handle all of the requests to the machine learning system powering those services.Rather than buy a bunch of new real estate and servers just for that purpose, the company embarked on a journey to create dedicated hardware for running machine- learning applications like voice recognition.The result was the Tensor Processing Unit (TPU), a chip that is designed to accelerate the inference stage of deep neural networks. Google published a paper on Wednesday laying out the performance gains the company saw over comparable CPUs and GPUs, both in terms of raw power and the performance per watt of power consumed.To read this article in full or to leave a comment, please click here

Worth Reading: Microservices to the Edge

There’s a hidden tension here. Once you put code at the edge you violate two of Lambda’s key assumptions: functions are composed using scalable backend services; low latency messaging. The edge will have a high latency path back to services in the datacenter, so how do you make a function based distributed application at the edge? Does edge computing argue for a more retro architecture with fewer messages back to a more monolithic core? —High Scalability

Is it crazy to be afraid of password managers?

I admit it: Like most people, I’m terrible at passwords. Too often I use too-simple passwords, and I don’t always come up with a new one for every site and service I log into. Then, when I do come up with a strong, unique password, I often forget it entirely and have to request an email to reset it—typically to something either too easy to guess or something I’ll instantly forget again.+ Also on Network World: Stop using password manager browser extensions + That’s why password managers exist. They’re designed to let you enter a single, secure password in one place and then generate new, strong passwords for every application where you need one.To read this article in full or to leave a comment, please click here

IoT garage door opener disabled over bad review, then re-enabled after backlash

When you take a chance and buy internet of insecure things devices, you already have to accept apps that have crazy overreaching permissions if you want your smart devices to work—and hope any vulnerabilities discovered will be patched. But should you have to worry about ticking off the device maker and having your device remotely disabled?There are all kinds of services and products that do not offer customer support on a Saturday night, which is frustrating when something goes wrong over the weekend and you need help. In the case of IoT garage door opener Garadget, unhappy customer Robert Martin wrote on a Garadget support thread:To read this article in full or to leave a comment, please click here

iPhone 8 Rumor Rollup: Fresh spate of delayed shipment speculation swirls; plus, good pricing news

Speculation is heating up again this week regarding the possibility that Apple might delay the arrival of its iPhone 8 (or iPhone X) smartphone until October or November due to technical issues related to the lamination of its new curved OLED displays as well as with its 3D sensing system.Apple historically has released its new flagship iPhones in September, but scuttlebutt in the supply chain says things could be otherwise in 2017. Speculation is that Apple could roll out its 7s and 7s Plus phones in September, with the high-end iPhone 8 becoming available shortly afterwards.MORE: Apple's Mobility Partner Program comes out of hidingTo read this article in full or to leave a comment, please click here

Zdravo, Beograde! Cloudflare network spans 30 European cities

Since Cloudflare began with our very first data center in Chicago, we are especially excited that our expansion takes us to its sister city. Where the Sava meets the Danube, Belgrade (Serbia) is home to Cloudflare’s 107th data center.

Пошто је Клаудфлер почео са првим дата центом у Чикагу посебно смо узбуђени што нас је наше ширење одвело у побратимљен град. Тамо где се Сава улива у Дунав, Београд, у Србији је дом Клаудфлеровог 107. дата центра.

Good-bye Internet pioneers. Hello, Oath?

After its acquisition of Yahoo wraps up, Verizon plans to place AOL and Yahoo under the umbrella of a new company, called Oath.AOL chief executive Tim Armstrong on Monday announced the move on Twitter, writing, "Billion+ Consumers, 20+ Brands, Unstoppable Team. #TakeTheOath. Summer 2017."AOL, which owns the Huffington Post, Engadget and TechCrunch, will pool all of the properties with Yahoo under the Oath umbrella, according to Armstrong, in an interview with CNBC."This is a sad thing for everyone who remembers when Yahoo and AOL were riding high," said Dan Olds, an analyst for OrionX. "For many people, AOL was their first experience with the Internet and was probably their first email address. A lot of people's first experience with Internet search, and other services, was probably with Yahoo. Unfortunately, the companies couldn't keep up with the ever-changing competition and fell into the backwaters of the Internet."To read this article in full or to leave a comment, please click here
