Micro-segmentation Defined – NSX Securing “Anywhere”

The landscape of the modern data center is rapidly evolving. The migration from physical to virtualized workloads, move towards software-defined data centers, advent of a multi-cloud landscape, proliferation of mobile devices accessing the corporate data center, and adoption of new architectural and deployment models such as microservices and containers has assured the only constant in modern data center evolution is the quest for higher levels of agility and service efficiency. This march forward is not without peril as security often ends up being an afterthought. The operational dexterity achieved through the ability to rapidly deploy new applications overtakes the ability of traditional networking and security controls to maintain an acceptable security posture for those application workloads. That is in addition to a fundamental problem of traditionally structured security not working adequately in more conventional and static data centers.

Without a flexible approach to risk management, which adapts to the onset of new technology paradigms, security silos using disparate approaches are created. These silos act as control islands, making it difficult to apply risk-focused predictability into your corporate security posture, causing unforeseen risks to be realized. These actualized risks cause an organization’s attack surface to grow as the adoption of new compute Continue reading

Technology Short Take #67

Welcome to Technology Short Take #67. Here’s hoping something I’ve collected for you here proves useful!

Networking

• Anthony Burke has written a script that uses VMware NSX to protect VMware Log Insight instances. More information on the script is in his blog post.
• Russ White tackles the issue of networking engineers needing to learn to code. Is it necessary? Russ thinks so—but probably not for the reasons you might think. I tend to agree with Russ’ line of thinking.
• This article from Marcos Hernandez shows one way to do dynamic routing in OpenStack. It’s a bit of a hack, to be honest, but it gets the job done until dynamic routing makes its way into OpenStack Neutron (which looks like it may have landed in the Mitaka release—can anyone confirm?).
• Jason Messer has an article describing how networking works with Windows containers.
• Tom Hollingsworth discusses how the rise of overlay networks killed large layer 2 networks and tools for building large layer 2 networks, like TRILL.
• Dmitri Kalintsev examines some options for addressing storage-related connectivity in NSX environments.

Servers/Hardware

• Drew Conry-Murray shines a light on Intel’s network ambitions. This is something I’ve been watching for a couple of years, Continue reading

Apple sends out invites for WWDC 2016

We already knew the dates for WWDC, but now it's 100% official. Apple yesterday began sending out invitations to select media outlets confirming that its annual developers conference will kick off at 10 am Pacific Time at the Bill Graham Civic Auditorium in San Francisco on June 13.Per usual, Apple's WWDC event will primarily, if not exclusively, focus on updates to various pieces of Apple software. That being the case, we'll most definitely get a sneak peak at iOS 10 and there's a good chance we'll also get a glimpse at the next-gen version of OS X.Operating systems aside, rumblings from the rumor mill suggest that Apple this year will finally open up Siri to third-party developers by way of an SDK. What's more, there's also a slight chance that Apple will roll out a complete overhaul of Siri itself. Also rumored to be on the agenda is a revamp of Apple Music. Though Apple's streaming music service already has upwards of 13 million subscribers, the service has been riddled with UI and various functionality issues.To read this article in full or to leave a comment, please click here

Apple’s enterprise partnerships, big and small, start to pay off

Apple has been the target of recent criticism for its current pace of innovation. However, though the company's slow-and-steady approach to the enterprise may not be winning over financial analysts, it is proving to be an effective strategy for expansion into the business market. Apple set the stage for a formal courtship of the enterprise nearly two years ago, when it inked an alliance with IBM. Since then, the company has struck deals with Cisco and SAP to tap the strengths of these stalwarts in enterprise services and mobility, in additional to a number of smaller players. To read this article in full or to leave a comment, please click here

How to embrace the benefits of shadow IT

The terms shadow IT conjures up negative images in the minds of most IT organizations. Yet non-IT enterprise functions and lines of business are buying more of their own IT systems than ever before, particularly product, operations and external customer-facing groups and highly dynamic services areas. “As business functions seek to realize the benefits from these non-traditional channels of IT enablement, the shadow IT organizations are growing aggressively in order to help orchestrate and aggregate services into business consumable offerings,” says Craig Wright, managing director of outsourcing and technology consultancy Pace Harmon.[ Related: 4 ways to apply SLAs to shadow IT ]To read this article in full or to leave a comment, please click here

SS8 makes enterprise version of traffic-analysis platform designed for intelligence agencies

SS8 built its network traffic-inspection and analysis platform as a tool for intelligence agencies to discover communications among criminals and terrorists but now has scaled it back for enterprises to stop data breaches.Called BreachDetect, the business-sized software gathers highly detailed network traffic data that discovers application flows and the activity of individual machines and analyzes them to find anomalies that indicate foul play.The platform also stores the information it collects so it can be analyzed over and over as new threat indicators are identified. That way corporate security pros can discover threats that may have been lurking undetected for months and figure out when and how they got there, SS8 says.To read this article in full or to leave a comment, please click here
