Survey: Zero Trust benefits remote work during pandemic

(Editor’s note: An August 2020 Enterprise Management Associates survey of 252 North American and European IT professionals found that most had accelerated their adoption of Zero Trust networking framework. This article by EMA Vice President of Research Networking Shamus McGillicuddy further details the results of the “Enterprise Zero Trust Networking Strategies: Secure Remote Access and Network Segmentation” report.)The COVID-19 pandemic has prompted 60% of enterprises to accelerate their Zero Trust networking strategies. Just 15% of organizations slowed down in response to the public-health crisis, and 25% reported no effect, according to Enterprise Management Associates research.To read this article in full, please click here

How to modifying user-account settings with usermod

There are quite a few changes you can make to user accounts on Linux systems: setting them up, deleting or disabling them, adding or removing users from secondary groups, changing usernames or UIDs, moving home directories, changing users’ shells, altering account expiration timing, and so on.One command that can make nearly all of these changes easier is usermod. The only real constraints are 1) that the accounts you intend to change must already exist on the system (this command won’t set them up from scratch), and 2) that the affected users should probably not be logged in when you make these changes.The basic syntax for the command is usermod [options] LOGIN but that options section has a lot more possibilities than you might anticipate. In addition, sudo permissions will be required for this command since superuser access is required to set up or change nearly all user account settings.To read this article in full, please click here

Cisco software upgrades to simplify hybrid-cloud management, operations

Cisco has upgraded some of its core software packages to help customers manage, control and automate functions in hybrid and multicloud data-center environments.With the needs of the pandemic-driven, highly distributed workforce as a backdrop, Cisco is looking to provide visibility and insights into what’s happening across customers’ cloud infrastructure. At the same time it's busting the siloed IT operations many customers have that hold back agile digital-application development, said Prashanth Shenoy, Cisco vice president of marketing. “Businesses are rethinking their IT platforms for multicloud operations, and we are providing the tools to  help them transform faster with insights and automation,” Shenoy said.To read this article in full, please click here

The Hedge Podcast #58: Michael Kehoe and eBPF

Most packet processing in Linux “wants” to be in the kernel. The problem is that adding code to the kernel is a painstaking process because a single line of bad code can cause havoc for millions of Linux hosts. How, then, can new functionality be pushed into the kernel, particularly for packet processing, with reduced risk? Enter eBPF, which allows functions to be inserted into the kernel through a sort of “lightweight container.”

Michael Kehoe joins Tom Ammon and Russ White to discuss eBPF technology and its importance.

Messaging Connectivity in a Hybrid Kubernetes Cloud Environment

KubeCon + CloudNativeCon North America 2020 – Virtual, Nov. 17-20. Lior Nabat Lior is KubeMQ’s technology leader and product architect. As a serial technology entrepreneur with over 20 years of experience in software ventures and product development, he brings cloud native expertise and hands-on experience. Lior founded Tradency (financial trading technology) 14 years ago and led as the CEO since inception. Previously he held key management positions at DSPG, Alpha Cell and TdSoft. Lior holds a B.A. in Mathematics and Computer Science from the Open University in Tel-Aviv Israel and AMP from the University of Pennsylvania-The Wharton School. @lior_nabat Hybrid cloud is a powerful IT architecture — backed by market leaders and used by many enterprise organizations — that connects a company’s on-premises, private cloud services and third-party, public cloud services into a single, flexible infrastructure for running the organization’s applications and workload. The principle behind hybrid cloud is a mix of public and private cloud resources — with a level of orchestration between them. This gives an organization the flexibility to choose the optimal cloud for each application or workload (and to move workloads freely Continue reading

NGINX Steps into the Service Mesh Fray Promising a Simpler Alternative

Earlier this month, NGINX NGINX Service Mesh (NSM), a free and open source service mesh that uses NGINX proxy, to power its data plane. While many service meshes are built from entirely open source components, NGINX Vice President of Marketing Aspen Mesh, the more advanced, Istio-based service mesh built by its now-parent company Service Mesh Interface (SMI) is not supported, but it is on the roadmap, and the NGINX Unit to “introduce something that’s a little bit different and more novel to advance the industry dialogue.” “We think there’s an option in the future to have a sidecar-less service mesh, where you’re not injecting sidecars in each service,” said Whitely. “Instead, you load your code, and you execute it, and the default runtime environment that’s executing your code has all the built-in proxying capabilities needed to handle east-west. It would take things down from a two container to one container kind of model.” Feature image by Unsplash.

What Is A Zero Trust Network Architecture

Every few years the industry takes a significant step towards a more holistic and capable security model. At the beginning, everything and everyone was trusted, and for good reason. You knew every operator and every machine that was connected to the network. But as networks have become ubiquitous, that level of trust is simply unreasonable. So we’ve built firewalls, and differing levels of inspection, but all of these tools still allow for some implicit level of trust between a machine and those machines closest to them. That is changing and that is what we’re here to talk about today. The newest trend in security is the concept of zero trust, and while it’s suffering the common plight of any new trend with multiple vendors trying to shape the definition, removing implicit trust in our networks is the next logical step towards a truly secure infrastructure.
