Cisco issues variety of security warnings on wireless gear

Cisco warned of a variety of vulnerabilities – from letting attackers issue DDOS attack to making devices unexpectedly reload -- in some of its wireless access point and LAN gear.The only critical alert came for vulnerability in Cisco Wave 2 Aironet 1830 Series and Cisco Aironet 1850 Series Access Points.In those devices, running Cisco Mobility Express Software, a vulnerability could let an unauthenticated, remote attacker take complete control of an affected device, the company stated.+More on Network World: Cisco expands wireless reach with access points, management software+To read this article in full or to leave a comment, please click here

More high-end GPUs are now compatible with Dell’s 8K monitor

Getting 8K displays to work with Windows 10 PCs can be difficult, as Dell is finding out.But playing with 8K on PCs is a discovery process for Dell, which shipped the first-ever 8K display -- the Dell 32 UltraSharp 8K Monitor -- last week. The small initial stock of the US$5,000 display sold out in a few days.The display won't work on all PCs and needs specific hardware and display ports. But Dell is finding out that more hardware than it originally thought can handle 8K graphics, including AMD's Radeon Pro WX 7100 workstation GPU.To read this article in full or to leave a comment, please click here

OPNFV “Danube” upgrade looks to spur open source NFV expansion

Looking to drive the use of Network Functions Virtualization, the OPNFV project this week released the fourth version of its open source platform, known as Danube, that promises to help large organizations and service providers get a better handle on virtualization, SDN and cloud services.+More on Network World: Open source routing project gets a vital technology infusion+Heather Kirksey, director, OPNFV said Danube melds a ton of work that has been done around NFV and brings DevOps methodologies to NFV. “It brings together full next-gen networking stacks in an open, collaborative environment. By harnessing work with upstream communities into an open, iterative testing and deployment domain, we’re delivering the capabilities that truly enable NFV,” Kirksey said.To read this article in full or to leave a comment, please click here

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.

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
