ICANN sets plan to reinforce internet DNS security

In a few months, the internet will be a more secure place. That’s because the Internet Corporation for Assigned Names and Numbers (ICANN) has voted to go ahead with the first-ever changing of the cryptographic key that helps protect the internet’s address book – the Domain Name System (DNS). [ Now see: The hidden cause of slow internet and how to fix it. ] The ICANN Board at its meeting in Belgium this week, decided to proceed with its plans to change or "roll" the key for the DNS root on Oct. 11, 2018. It will mark the first time the key has been changed since it was first put in place in 2010.To read this article in full, please click here

How we did it: 10 hot hybrid-cloud startups to watch

The selection process for our 10 hot hybrid-cloud startups to watch roundup began with 42 recommendations and nominations that came to me via HARO, LinkedIn, Twitter and subscribers to my Startup50 email newsletter.For this roundup, we focused on hybrid-cloud infrastructure and hybrid-cloud-enabling technologies. Thus, cloud-delivered applications that don’t enable clouds but, rather, rely on them, were eliminated. We also eliminated cloud security startups because they belong in their own roundup or in a security roundup.[ Now read 20 hot jobs ambitious IT pros should shoot for. ] This left me with 23 startups. The next set of cuts were the easiest ones. Startups that were slow to respond to questions – missing deadlines and forcing me to chase them down just to get answers to my questions – were eliminated.To read this article in full, please click here

Is predictive maintenance the ‘gateway drug’ to the Industrial IoT?

I’ve said it before, but it bears repeating: When it comes to the Internet of Things (IoT), the consumer market gets all the attention, but the real action may be in industrial applications, the so-called Industrial Internet of Things (IIoT).The IIoT is a huge market, and it’s based more on clearly defined cost savings than the always-fickle consumer preferences that seem to rule the consumer market. It also requires highly available infrastructure to connect everything and avoid expensive downtime — one reason why investment in IIoT firms has been hot this summer, with investments in companies such as Seeq, Element Analytics, Trendminer, Falkonry, and Toumetis.To read this article in full, please click here

Linux tricks that even you can love

Good Linux command line tricks don’t only save you time and trouble. They also help you remember and reuse complex commands, making it easier for you to focus on what you need to do, not how you should go about doing it. In this post, we’ll look at some handy command line tricks that you might come to appreciate.Editing your commands When making changes to a command that you're about to run on the command line, you can move your cursor to the beginning or the end of the command line to facilitate your changes using the ^a (control key plus “a”) and ^e (control key plus “e”) sequences.You can also fix and rerun a previously entered command with an easy text substitution by putting your before and after strings between ^ characters -- as in ^before^after^.To read this article in full, please click here

Why banks didn’t ‘rip and replace’ their mainframes

Consumer demand for instant 24-hour access to personal bank data has taken the financial world in a new direction in less than one generation. Not only do bank IT departments now rival those of software development companies, but banking networks and infrastructure are at least as complex as a tech firm’s. Personal financial information has become one of the most protected and heavily regulated types of data in the world, and security measures and compliance programs consume the largest percentage of a financial institution’s IT budget.Knowing all this, it’s no wonder the “rip and replace” fad of the early 2000’s never materialized in the banking world. With everyone assuming the turn of the millennium meant “out with the old and in with the new,” companies were ready to rip the mainframes out of their infrastructure to prepare for whatever was next. But what came next never really materialized — or continued to prove inferior to the sheer processing power of the mainframe, which remains the only real choice for high-demand business computing.To read this article in full, please click here

Georgia Tech research: Smart building and IoT technology are highly fragmented

Greater cooperation among standards bodies, corporations, city governments and other stakeholders is needed so IoT and existing smart-building technology can work together to deliver the full potential of smart cities, according to a Georgia Tech study.The problem is that standards are lacking for current in-building systems, let alone having standards so they can share with newer IoT devices.[ Check out our corporate guide to addressing IoT security. ] One vendor of automation software for, say, elevators might use a much different data format than the manufacturer of a given building’s HVAC systems, making it difficult to integrate these two critical systems into the same framework.To read this article in full, please click here

IDG Contributor Network: Beware the networking industrial complex

There is a status quo in the networking industry that is the enemy of innovation. The major hardware equipment makers collectively benefit by propagating the many layers of equipment and protocols. This “deep state” that exists within our innovation economy must be defeated to unleash the next wave of innovative networking, which will be software-based and ideally designed to support business applications and services.One leader of the Networking Industrial Complex has a certified army of mercenaries that are compensated by unsuspecting enterprises to architect networks. These mercenaries attend training camps to be reprogrammed on a frequent basis. Examinations are held to ensure compliance. This entire system ensures that networking architectures, techniques and methods will not change. It’s no wonder many executives of companies are handing the keys to IT and networking to third parties.To read this article in full, please click here

IDG Contributor Network: 5 ways to derail IT transformation projects

Projects involving virtualization, cloud architectures, advanced networking and cutting-edge digital technologies are critical to pushing a company into the future. As a result, missteps can be costly. Take a good idea on paper, execute it poorly, and your desire to create value will end up squandering value.Given the complexity of IT transformation projects, there are many ways to get them wrong. If you've ever been called upon to assist companies stuck in the middle of such projects (as has our team, many times) it’s easy enough to identify several sure-fire ways to derail them – and corresponding ways to keep them on track. Here are five:1. Trivialize the effort required Have you ever sat in a meeting and heard an executive dismiss the difficulty of a project? "That sounds easy!," he or she might say. Whether it’s a desire for the project to be completed, a lack of knowledge about the details, the planning fallacy or some other error, following that lead is a good way to set yourself up for failure.To read this article in full, please click here

IDG Contributor Network: 4 ways next generation NPMD solutions reduce risk in network transitions

Forced to keep pace with rapidly emerging business requirements, networks are changing faster than ever. The business-facing side of networking is under continuous pressure to do more, in more places, faster. Challenging as it is, the network-to-business interaction is simpler than what is going on behind the scenes, as network professionals transform almost every area of their networks to meet new demands.New technologies such as cloud, NFV and SDN are turning traditional networks into hybrid ones. In fact, Gartner predicts that cloud infrastructure services will grow 35.9 percent in 2018, and IDC predicts that SD-WAN adoption will grow at a 40.4 percent CAGR from 2017 to 2022. These numbers imply a great deal of change in networks, change that introduces significant risk of service disruption from minor – a few inconvenienced users – to major – significant outages visible to customers and executives. Reducing the risk during significant transitions is critical. That’s where network performance management and diagnostics (NPMD) products play a significant role.To read this article in full, please click here

IDG Contributor Network: Cutting complexity at the edge

The edge is top-of-mind for many IT and OT professionals across a wide range of industries and sectors. This interest is driven by the need to use data more effectively to maintain operations, optimize performance and increase uptime.Existing IT and OT infrastructures typically don’t collect, store and analyze data at the edge. They instead either send this data to the cloud or to enterprise-level computing systems for storage and analysis, the domain of IT personnel.A better solution, specifically for applications where access to data needs to happen quickly, is to perform data collection, storage and analysis at the edge using technologies designed to perform these specific tasks. The benefits of this approach include reduced latency, improved data security and more efficient use of bandwidth.To read this article in full, please click here

6G will achieve terabits-per-second speeds

The first of the upcoming 5G network technologies won’t provide significant reliability gains over existing wireless, such as 4G LTE, according to a developer involved in 5G.Additionally, the millisecond levels of latency that the new 5G wireless will attempt to offer—when some of it is commercially launched, possibly later this year—isn’t going to be enough of an advantage for a society that’s now completely data-driven and needs near-instant, microsecond connectivity.“Ultra-reliability will be basically not there,” Ari Pouttu, professor for Dependable Wireless at the University of Oulu, told me during a visit to the university in Finland. 5G’s principal benefits over current wireless platforms are touted as latency reduction and improved reliability by marketers who are pitching the still-to-be-released technology.To read this article in full, please click here
