DNS over HTTPS seeks to make internet use more private

Unauthorized interception of DNS traffic provides enough information to ascertain internet users’ thoughts, desires, hopes and dreams.  Not only is there concern for privacy from nearby nosey neighbors, but governments and corporations could use that information to learn about individuals’ internet behavior and use it to profile them and their organization for political purposes or target them with ads. To read this article in full, please click here(Insider Story)

Dell EMC committed to networking, shares product and partnership plans

Dell EMC has one of the broadest networking portfolios in the industry. What’s unique about Dell EMC’s approach is that it's a mix of its own technology, as well as network partners. Also, it offers traditional hardware products and software-only products and supports white-box implementation. As an industry watcher, I’ve always been confused by the strategy of Dell EMC Networking. I know I’m not alone in this, as other network professionals I’ve talked to have echoed this sentiment.Recently, I had an opportunity to talk with Tom Burns, senior vice president and general manager of Dell EMC Networking and Solutions, about the company's networking portfolio and asked if he could clarify what is included in it.To read this article in full, please click here

Retail IoT is still coming into its own in 2019

Retailers see some tantalizing possibilities for using IoT technology in their businesses, but 2019 seems likely to feature more pilot programs and small-scale testing than widespread upheaval.Bridging the gap between online and in-person shopping, increased automation, and new ways to engage with customers (mostly by showing them ads) are all concepts with major upside for retailers, but the technology has only recently started to take hold.[ Related: What is the IoT? How the internet of things works. ] Some of IoT’s presence in the retail world isn’t retail-specific. Companies use asset-management systems, integrated HVAC and other smart-building tech just like many other industries, according to analysts, but physical retailers have been having a tough time across the board lately, and investments in new technology can quickly fall down priority lists.To read this article in full, please click here

Sigfox president on building a one-stop-shop for IoT cloud communications

How to add IoT functions to legacy equipment

Powerful new Internet of Things (IoT) devices promise to revolutionize everything from farm equipment to satellites. But can those benefits also be added to the enormous installed base of existing, legacy, equipment, and infrastructure? After all, much of that stuff has been in place for decades, if not centuries, and still works just fine. Replacing it all would cost untold trillions, so no matter what the possible profits might be, it’s unlikely to fall out of service any time soon.To read this article in full, please click here

GPUs are vulnerable to side-channel attacks

Computer scientists at the University of California at Riverside have found that GPUs are vulnerable to side-channel attacks, the same kinds of exploits that have impacted Intel and AMD CPUs.Two professors and two students, one a computer science doctoral student and a post-doctoral researcher, reverse-engineered a Nvidia GPU to demonstrate three attacks on both graphics and computational stacks, as well as across them. The researchers believe these are the first reported side-channel attacks on GPUs.[ Read also: What are the Meltdown and Spectre exploits? | Get regularly scheduled insights: Sign up for Network World newsletters ] A side-channel attack is one where the attacker uses how a technology operates, in this case a GPU, rather than a bug or flaw in the code. It takes advantage of how the processor is designed and exploits it in ways the designers hadn’t thought of.To read this article in full, please click here

BrandPost: Top Ten Reasons to Think Outside the Router #8: Garbled VoIP Calls and Pixelated Video

How often have you been on a VoIP call only to experience dropouts or garbled sound? Or endured a video conference with pixelated images or even a frozen screen? The expanding use of Unified Communications (UC) applications has placed increased pressure on IT to deliver an exceptional user experience to employees. But when user experience deteriorates enough, it results in a flood of calls to the IT help desk. Delivering consistent, high quality real-time communications is difficult, if not impossible, with a traditional router-centric wide area network architecture.Why? Because conventional routers can’t overcome inevitable packet loss that negatively impacts quality voice and video communication quality and the user’s experience and productivity. WAN architectures based on traditional routers typically backhaul all traffic to a headquarters-based data center, adding latency or delay that contribute to poor quality.To read this article in full, please click here

Making the right hyperconvergence choice: HCI hardware or software?

Once a niche technology, primarily attractive to organizations with specific needs, such as streamlining operations at branch offices, hyperconverged infrastructure (HCI) is rapidly finding a wide customer base.HCI is an IT framework that combines storage, computing and networking into a single system; hyperconverged platforms include a hypervisor for virtualized computing, software-defined storage, and virtualized networking.Enterprises planning an HCI adoption can select from two main approaches: hardware or software. HCI hardware typically comes in the form of an integrated appliance, a hardware/software package created and delivered by a single vendor. Appliance vendors include Dell EMC, Nutanix and HPE/SimpliVity. A software-only offering allows customers to deploy HCI on a bring-your-own-technology basis. HCI software vendors include Maxta and VMware (vSAN).To read this article in full, please click here

Itential puts organizations on the path to the modern network

In the realm of enterprise computing, we have already automated the management and orchestration of software-defined compute and storage resources. Need another server or more storage capacity? Those virtual resources can be created in mere minutes — and without intervention from a human to initiate or manage the process.Need changes to the network, such as a router reconfiguration? Well, that’s going to take a lot of time and effort from a range of humans. Even something as simple as an update to a DNS or IPAM server can take three to five days to complete. A port turn-up can take just as long — not because any physical action takes that much time, but because the workflow of all the human reviews and approvals takes time.To read this article in full, please click here

How to make the business case for SD-WAN

Entegra Bank, a fast-growing financial institution based in the Blue Ridge Mountains of North Carolina, switched from MPLS links for its 22 branches to SD-WAN-based broadband and slashed its WAN connectivity bill by 50%, while increasing bandwidth an average of fivefold.Loren Long, senior vice-president and CTO at the bank, says he had been eyeing both SD-WAN and broadband for some time, waiting for SD-WAN technology to mature and for rural broadband to improve in availability, dependability and security. After a positive experience with Silver Peak’s WAN optimization gear, “we felt confident to make that change,” he says.In a typical SD-WAN scenario, branch office broadband would connect directly to the public Internet. But since this a bank with heightened security and compliance responsibilities, traffic from the branches is backhauled over an encrypted VPN to internal gateways, where a third-party security services provider monitors all traffic and enforces security policies.To read this article in full, please click here

What is WPA3? Wi-Fi security protocol strengthens connections

The Wi-Fi Alliance has introduced the first major security improvement to Wi-Fi in about 14 years: WPA3. The most significant additions to the new security protocol are greater protection for simple passwords, individualized encryption for personal and open networks, and even more secure encryption for enterprise networks.The original Wi-Fi Protected Access (WPA) standard was released back in 2003 to replace WEP, and the second edition of WPA came the year after. The third edition of WPA is a long-awaited and much-welcomed update that will benefit Wi-Fi industry, businesses, and the millions of average Wi-Fi users around the world—even though they might not know it.To read this article in full, please click here
