Not So Fast Ansible, Cisco IOS Can’t Keep Up…

Remember how earlier releases of Nexus-OS started dropping configuration commands if you were typing them too quickly (and how it was declared a feature ;)?

Mark Fergusson had a similar experience on Cisco IOS. All he wanted to do was to use Ansible to configure a VRF, an interface in the VRF, and OSPF routing process on Cisco CSR 1000v running software release 15.5(3).

Here’s what he was trying to deploy. Looks like a configuration straight out of an MPLS book, right?

The Revenge of the Ancillaries

Have you ever tried to make water flow in a specific direction? Maybe you have some particularly muddy spot in your yard, so you dig a small ditch and think, “the water will now flow from here to there, and the muddy spot won’t be so muddy the next time it rains.” Then it rains, and the water goes a completely different direction, or overflows the little channel you’ve dug, making things worse. The most effective way to channel water, of course, is to put it in pipes—but this doesn’t always seem to work, either.

The next time you think about shadow IT in your organization, think of these pipes, and how the entire system of IT must look to a user in your organization. For instance, I have had corporate laptops where you must enter two or three passwords to boot the laptop, provided by departments that require you to use your corporate laptop for everything, and with security rules forbidding the use of any personal software on the corporate laptop. I have even had company issued laptops on which you could not modify the position of icons on the desktop, change the menu items in any piece Continue reading

Build security into your IoT plan or risk attack

The Internet of Things (IoT) is no longer some futuristic thing that’s years off from being something IT leaders need to be concerned with. The IoT era has arrived. In fact, Gartner forecasts there will be 20.4 billion connected devices globally by 2020.An alternative proof point is the fact that when I talk with people about their company's IoT plans, they don’t look at me like a deer in headlights as they did a few years ago. In fact, often the term “IoT” doesn’t even come up. Businesses are connecting more “things” to create new processes, improve efficiency, or improve customer service.As they do, though, new security challenges arise. One of which is there's no “easy button.” IT professionals can’t just deploy some kind of black box and have everything be protected. Securing the IoT is a multi-faceted problem with many factors to consider, and it must be built into any IoT plan.To read this article in full, please click here

IDG Contributor Network: The cloud-based provider: Not your grandfather’s MNS

Today, the wide area network (WAN) is a vital enterprise resource. Its uptime, often targeting availability of 99.999%, is essential to maintain the productivity of employees and partners and also for maintaining the business’s competitive edge.Historically, enterprises had two options for WAN management models — do it yourself (DIY) and a managed network service (MNS). Under the DIY model, the IT networking and security teams build the WAN by integrating multiple components including MPLS service providers, internet service providers (ISPs), edge routers, WAN optimizers and firewalls.The components are responsible for keeping that infrastructure current and optimized. They configure and adjust the network for changes, troubleshoot outages and ensure that the network is secure. Since this is not a trivial task, therefore many organizations have switched to an MNS. The enterprises outsource the buildout, configuration and on-going management often to a regional telco.To read this article in full, please click here

The IoT brings targeted advertising into retail stores

The Internet of Things (IoT) is everywhere these days, from smart houses to smart cities to industrial applications. And now it’s coming to the coolers in a drugstore near you.Walgreens is testing innovative, IoT-powered "smart coolers" that combine cameras, facial recognition software, and display screens in the cooler doors to serve targeted ads depending on what it can tell about shoppers rooting around for cold drinks and frozen treats.[ Read more about IoT: Download a PDF bundle of five essential articles about IoT in the enterprise ] Bringing the online ad experience in store According to the Wall Street Journal, the system attempts to recreate the online advertising experience in brick and mortar stores, using facial recognition software to determine the age of the shopper and what products they’ve already selected — as well as environmental factors — to determine what ads to show. Supplied by Chicago-based Cooler Screens, the technology is designed to transform “retail cooler surfaces into IoT-enabled screens and [create] the largest retail point-of-sale merchandising platform in the world.”To read this article in full, please click here
