How to prevent IPv6 VPN breakout

Enterprises unaware of the role IPv6 plays on remote users’ devices run the risk that these machines might access banned sites despite using VPNs that are meant to restrict what they access.This hole stems from the fact that some of these remote-access VPNs are configured to inspect and apply security controls only to IPv4 traffic as it passes through a VPN concentrator without enabling similar protections for IPv6 traffic.[Get regularly scheduled insights by signing up for Network World newsletters.] This leaves IPv6 traffic free to access the Internet directly without those controls being applied. Known as IPv6 VPN breakout, the issue is well known yet often remains overlooked.To read this article in full, please click here

Linux sudo flaw can lead to unauthorized privileges

A newly discovered and serious flaw in the sudo command can, if exploited, enable users to run commands as root in spite of the fact that the syntax of the /etc/sudoers file specifically disallows them from doing so.Updating sudo to version 1.8.28 should address the problem, and Linux admins are encouraged to do so as soon as possible. [Get regularly scheduled insights by signing up for Network World newsletters.] How the flaw might be exploited depends on specific privileges granted in the /etc/sudoers file. A rule that allows a user to edit files as any user except root, for example, would actually allow that user to edit files as root as well. In this case, the flaw could lead to very serious problems.To read this article in full, please click here

DiversyFund makes real estate investment accessible to everyone

Few investment opportunities are as lucrative as real estate. By buying low, renovating, and selling when the time is right, investors have the potential to make millions of dollars in profit. Unfortunately, this practice is typically reserved for the ultra-wealthy since buying a single property let alone building a real estate portfolio requires more than most of us have lying around. The good news for the 99% is that financial tech company, DiversyFund, is on a mission to change that. With DiversyFund, anyone can participate in building a diversified real estate portfolio, and all you need is $500 to get started. To read this article in full, please click here

IDG Contributor Network: The software-defined data center drives agility

In this day and age, demands on networks are coming from a variety of sources, internal end-users, external customers and via changes in the application architecture. Such demands put pressure on traditional architectures.To deal effectively with these demands requires the network domain to become more dynamic. For this, we must embrace digital transformation. However, current methods are delaying this much-needed transition. One major pain point that networks suffer from is the necessity to dispense with manual working, which lacks fabric wide automation. This must be addressed if organizations are to implement new products and services ahead of the competition.To read this article in full, please click here

Overcoming the Barriers to Micro-segmentation

It should come as no surprise how much emphasis organizations place on security today. Threats are becoming more and more sophisticated and the number of threats grow to uncontrollable rates every day.

One of the biggest downsides is that the rising cost of data breaches in 2019 alone, a global average of $3.92 million as reported by the Ponemon Institute and IBM Security July 2019 report, is enough to cause organizations to rethink or increase emphasis on their security strategies and how they can help secure their most important assets by improving the cyber hygiene in their organizations.

What is Cyber Hygiene?

Cyber hygiene refers to what an organization can do to improve their security postures around physical hardware, software, and applications. If you’ve seen Pat Gelsinger’s keynote from 2017, he goes into the 5 pillars of good cyber hygiene and what organizations can do to improve basic and fundamental security for their business.

Over the last several years, VMware has been focusing on helping organizations move to Software-Defined Data Centers (SDDC) to improve their agility and meet the speed of business. As more organizations adopted the SDDC model, VMware found itself in a unique position Continue reading

IDG Contributor Network: Nutanix and HPE’s new hybrid partnership

The hybrid cloud and hyper converged infrastructure (HCI) markets have become an important discussion as more and more companies are looking at cloud as an operating model. This also means more new products set to hit the market to support the growth in Hybrid Cloud and HCI adoption, which will raise a series of questions for enterprises as to which solutions and tools it will adopt, consume and use to deploy workloads, both on-prem and utilizing public cloud infrastructure. As digital transformation, customer experience, and business outcomes take center stage, we are seeing the infrastructure itself become an enabler, but where the infrastructure is placed has been more fluid. With hyperscalers like AWS moving workloads on-prem, and IT vendors like Cisco, Dell/VMware, and HPE (who traditionally built solutions for on-prem), ramping up offerings for the cloud, we have most certainly reached a tipping point. The phase we are now entering is the phase where infrastructure moves to the background and the market shifts to the need for compute that is charged on an ‘as used,’ or consumption model.

BrandPost: A Business-driven SD-WAN Brings Well-Being to Healthcare Providers

This is the first installment of a multi-part blog series that will provide an overview of how technology is dramatically reshaping the healthcare industry and how the wide area network (WAN) can significantly affect innovation acceleration and customer satisfaction in this sector.Like many other industries, the healthcare industry is also undergoing a digital transformation. And, despite being always considered “behind the times” in leveraging information technology, the delivery of healthcare services is becoming more and more modern and data-driven each day. The evolution in data, mobile and cloud technologies is driving healthcare providers to shift from a provider-driven toward a patient-centric business model. Patients today have the same expectations of healthcare providers as they have of any retailer or any other product or service, and they want healthcare on their own schedule and even on-demand.To read this article in full, please click here

Beamforming explained: How it makes wireless communication faster

Beamforming is a technique that focuses a wireless signal towards a specific receiving device, rather than having the signal spread in all directions from a broadcast antenna, as it normally would. The resulting more direct connection is faster and more reliable than it would be without beamforming.Although the principles of beamforming have been known since the 1940s, in recent years beamforming technologies have introduced incremental improvements in Wi-Fi networking. Today, beamforming is crucial to the 5G networks that are just beginning to roll out.To read this article in full, please click here

How Do You Provision a 500-Switch Network in a Few Days?

TL&DR: You automate the whole process. What else do you expect?

During the Tech Field Day Extra @ Cisco Live Europe 2019 we were taken on a behind-the-stage tour that included a chat with people who built the Cisco Live network, and of course I had to ask how they automated the whole thing. They said “well, we have the guy that wrote the whole system onsite and he’ll be able to tell you more”. Turns out the guy was my good friend Andrew Yourtchenko who graciously showed the system they built and explained the behind-the-scenes details.

Keeping NATS Connections DRY in Go

In the previous posts, I covered the basics of connecting to NATS in Go and the different ways subscribers can request information is sent to them. In this post, I’d like to build on those concepts by exploring how to structure your NATS-powered Go code so that things are clean and DRY. I’ll also show that trying to make things too DRY can be problematic; as with everything, moderation is a good idea.
