BrandPost: Silver Peak 2018 CEO Predictions

Enterprises adopt cloud-first WAN architecturesToday, most WAN traffic, to and from branch and remote sites, is destined for the cloud, either to SaaS services or applications hosted in an IaaS environment. The traditional WAN was architected for branch-to-data-center traffic flows, not to efficiently support new cloud-driven traffic patterns. Starting in 2018, most enterprises will adopt a “cloud-first” SD-WAN architecture designed to efficiently and effectively support the ongoing evolution in their application mix.The new WAN edge replaces the traditional branch routerTraditional routers are no longer the default choice for branch deployments. Routers are burdened by three decades of complexity and a cumbersome “CLI-first” device-by-device configuration paradigm. With SD-WAN as a foundation, a new class of centrally-orchestrated, application-driven WAN edge devices will replace traditional routers in the branch.To read this article in full, please click here

Meltdown and Spectre: How much are ARM and AMD exposed?

As the chip vendors wrestle to get their arms around the Meltdown and Spectre vulnerabilities, we’re slowly determining the exposure of AMD and ARM to the exploit. Intel, unfortunately, is totally vulnerable. With AMD and ARM, though, it gets complicated.First, let’s go over the Spectre exploit, which is a second class of attacks similar to Meltdown, the one we all know. Like Meltdown, Spectre exploits speculative execution in order to root out information from a CPU’s cache. Spectre is different because of how it runs.Also read: Meltdown and Spectre exploits: Cutting through the FUD While Meltdown is based on a specific implementation of speculative execution, Spectre exploits a risk to speculative execution that requires more work to exploit but is also considered harder to mitigate. Because it’s more obscure and arcane, it’s not as well understood. That’s why Meltdown is considered the bigger risk.To read this article in full, please click here

Red Hat responds to the Intel processor flaw

How are the Linux vendors addressing the recently-exposed Intel processor flaw? I asked Red Hat and got some solid answers.What is the nature of the problem? Discovered some time ago, but only just yesterday brought into public view, the CPU flaw allows an attacker to bypass restrictions to gain access to privileged memory (which should be inaccessible) -- possibly stealing sensitive information from computer systems, mobile devices, and cloud deployments. There are actually two problems and they've been dubbed "Meltdown" and "Spectre". They potentially affect 90% of computer servers and virtually every Intel microprocessor.The Meltdown flaw is specific to Intel while Spectre is a design flaw that has been used by many processor manufacturers for decades.To read this article in full, please click here

IDG Contributor Network: Is it time for a network tax cut?

It is truly remarkable to what extent corporate and personal behavior is dictated by tax policy. Much of the discussion in our nation’s capital in regard to tax reform has been about competitiveness as a rational to lower corporate tax rates. It appears as though the United States charges a 20 percent higher tax rate than much of the rest of the world, forcing corporations to shift some operations and assets into lower tax rate jurisdictions. It’s safe to say that tax policy impacts behavior in measurable ways.Just yesterday I was speaking with a communications service provider analyst. We discussed the overhead of SD-WAN tunnels. I showed the math of how it can tax various protocols. The tax for various protocols was:To read this article in full, please click here

IDG Contributor Network: 3 ways networking will change for the better in 2018

As I discussed in "Why web-scale is the future," over the past year, we’ve seen more organizations embrace it as the “go-to” model for flexible, resilient and on-demand infrastructure. Gartner predicts that by 2020, 40% of global enterprise CIOs will have initiated a corporate web-scale IT initiative.As web-scale principles continue their rise within large enterprises, the role the network plays for the business, as well as the day-to-day working lives of network engineers, will change in some pretty significant ways in the year ahead.1. Networks will help fuel digital transformation rather than slow it down 40 percent of CEOs rank digital transformation as their top imperative, according to a recent Economist Intelligence Unit survey. More than ever, digital transformation is crucial to business success; in 2018, spending on the software, hardware and services that enable digital transformation will reach nearly $1.3 trillion, predicts analyst firm IDC. This figure “represents a 16.8 percent jump compared to the $1.1 trillion spent this year” (Datamation).To read this article in full, please click here

Secure your SDN controller

Managing networks has become increasingly complex, and it will remain a challenge as the use of Internet of Things devices continues to grow. This complexity makes it difficult to reconfigure a traditional network in a timely manner to respond to malicious events or fix configuration errors.A software-defined network (SDN) can help by giving network engineers the flexibility to dynamically change the behavior of a network on a node-by-node basis — something not typically available in a traditional network. An SDN uses virtualization to simplify the management of network resources and offers a solution for increased capacity without significantly increasing costs.To read this article in full, please click here

IDG Contributor Network: How IoT trackers can fight poachers

Sea turtles have been survived for millions of years, but now face extinction.  as poachers. How do you protect sea turtles eggs on remote, miles-long beaches in developing countries from poachers working in the dark?Global System for Mobile Communications, or GSM, enabled IoT trackers may provide an answer to this scourge.Background Poachers kill sea turtles for their shells and their eggs are considered a delicacy and aphrodisiac. Sad but true. The trade of sea turtle products is restricted, but that doesn’t stop poachers. Tracking this illegal trafficking is difficult. The transit routes and final destinations are unknown.Sea turtle products are the second most frequently trafficked wildlife product smuggled from Latin America to the US. Eggs are a quarter of illegal imports and most originate in Mexico or Central America. This trade is devastating to turtle populations. A recent shipment of a thousand turtle eggs that was intercepted at the Mexico/U.S. border represented nearly 5 percent of the year’s total egg production for the beach from which they were poached!To read this article in full, please click here

IDG Contributor Network: How interconnection can set the pace as holiday shopping gets more digital

The arrival of the holiday shopping season always brings sharp focus onto ecommerce, which just keeps disrupting how retailers and consumers shop. But it’s striking just how much running room remains in front of this trend, which already has a couple decades of Christmases under its big black Santa belt.According to eMarketer, ecommerce sales will grow more than 23 percent in 2017 – and still only account for a tenth of retail sales globally. Opportunities remain huge in the online shopping sector, but only if companies can continue to keep the digital payments at the heart of it simple, fast and secure for consumers and retailers alike. That’s a perpetual challenge.To read this article in full, please click here

Squinting at ASCII on Linux

Back when I started working with computers, understanding the nature of ASCII was exciting. In fact, just knowing how to convert binary to hex was fun.That was a lot of years ago — berfore ASCII had yet reached drinking age — but character encoding standards are as important as ever today with the internet being so much a part of our business and our personal lives. They're also more complex and more numerous than you might imagine. So, let’s dive into some of the details of what ASCII is and some of the commands that make it easier to see coding standards in action.Why ASCII? ASCII came about to circumvent the problem that different types of electronic systems were storing text in different ways. They all used some form of ones and zeroes (or ONs and OFFs), but the issue of compatibility became important when they needed to interact. So, ASCII was developed primarily to provide encoding consistency. It became a standard in the U.S. in 1960. Initially, ASCII characters used only 7 bits. Some years later, ASCII was extended to use all 8 bits in each byte.To read this article in full, please click here

New Seagate tech promises to double hard drive speeds

Unable to even come close to SSDs in terms of performance, hard disk makers have chosen to compete with capacity. A SSD over 1TB in size starts to become expensive, especially for consumers, so HDD makers Seagate and Western Digital have gone for massive capacity, introducing drives with up to 14TB of capacity.But now Seagate promises greater speed thanks to a new drive head technology. Dubbed the multi-actuator technology, it’s a simple idea that’s been around a while but wasn’t economically viable in the past due to higher component costs.Hard drive heads are connected to an arm called an actuator. This moves back and forth across the disk while the disk spins. Hard drives have multiple platters for storing data, and the actuator arms have drive heads on both sides of the platter, since data is written to both sides of the platter.To read this article in full, please click here

The time to deal with IoT security is now

In most cases, I try to turn a skeptical eye on hyperbole. So when a cybersecurity expert tells me that IoT security is a “ticking time bomb,” my initial reaction is not to worry about an upcoming “security apocalypse.”But I am already worried about security in the Internet of Things. So, I took the opportunity to ask Srini Vemula, global product management leader and security expert at SenecaGlobal, what’s really at risk as we hurtle toward 2020 and an estimated 20.4 billion connected devices.To read this article in full, please click here
