How SD-WAN is evolving into Secure Access Service Edge

SASE, pronounced "sassy," stands for secure access service edge, and it's being positioned by Gartner as the next big thing in enterprise networking. The technology category, which Gartner and other network experts first introduced earlier this year, converges the WAN edge and network security into a cloud-based, as-a-service delivery model. According to Gartner, the convergence is driven by customer demands for simplicity, scalability, flexibility, low latency, and pervasive security.SASE brings together security and networking A SASE implementation requires a comprehensive technology portfolio that only a few vendors can currently deliver. The technology is still in its infancy, with less than 1% adoption. There are a handful of existing SD-WAN providers, including Cato Networks, Juniper, Fortinet and Versa, that are expected to compete in the emerging SASE market. There will be other SD-WAN vendors jumping on this wagon, and the industry is likely to see another wave of startups. To read this article in full, please click here

NSX Cloud – Choice of Agented or Agentless Modes of Operation

VMware NSX through its NSX Cloud offering enables customers to implement a consistent networking and security framework for workloads hosted across on-premises data center (DC) and public clouds such as AWS and Azure.

Every cloud orchestration and management tool, immaterial of what use case it has set out to solve has one question to answer: If it is an agent-based solution or an agentless solution. More often than not, the answer to this question has direct implications for the ability of the cloud admin team to deploy and manage the solution.

But, do we really have to choose?! What if we can have both agented and agentless modes of operation?! That’s the question we asked ourselves with VMware NSX and here we are with NSX-T 2.5.

Meet the New NSX Cloud Modes of Operation

What is NSX Enforced Mode?

NSX Enforced Mode provides a “consistent” security and networking policy framework between your on-premises DC and public cloud environment. You can have a unifiedcorporate-wide-firewall-policy which will be enforced as an NSX Policy, by having an nsx footprint inside each virtual machine running in the cloud.

Why is it Required?

Well, NSX architecture has 3 layers:

  • Management-plane
  • Control-plane
  • Data-plane

IoT roundup: Carriers expand NB-IoT footprints, Congress eyes security bill, and ‘IT asbestos’ looms

The major U.S. mobile carriers are eager participants in the rise of IoT, and it’s tough to argue that they don’t have a major role to play – the ability to connect largely anywhere, coupled with the ability to handle high-throughput applications, means that cellular data can be an attractive option for the connectivity piece of an IoT deployment.AT&T announced a deal with Vodafone last week to interconnect their respective narrow-band IoT networks across the Atlantic, mating AT&T’s U.S. coverage with Vodafone’s in western Europe. That means that businesses with NB-IoT deployments in those areas can use that single network to connect their entire implementation. Not to be outdone, Sprint announced that it, too, is rolling out NB-IoT on its Curiosity IoT platform. Sprint shared its plans during a panel discussion at Mobile World Congress in Los Angeles last week.To read this article in full, please click here

This 4-course VMware mastery bundle is on sale today for just $20

An IT server is costly but necessary to run a network, and most businesses employ many of them. A great way to get the most out of a servers’ physical resources is through virtualization, which allows a server to create a host an operating system using virtual machine software such as VMware. This essentially creates a “computer within a computer”, and you can learn how to do so with this $20 bundle.To read this article in full, please click here

The Week in Internet News: U.S. Big Tech Firms Skip Chinese Internet Conference

Not our model: Google, Twitter, Facebook, and Apple skipped a Chinese conference focused on a global governance model for the Internet, Asia One reports. During the conference, China promoted its highly restrictive model of the Internet. Google, Twitter, and Facebook are blocked in China, while Apple must use a local partner to offer cloud services, the story notes.

No news for you: Meanwhile, the Chinese government’s Great Firewall blocks 23 percent of the news organizations that have journalists stationed in the country, reports the South China Morning Post, citing statistics from the Foreign Correspondents’ Club of China. Nearly a third of English-language sites are blocked. Blocked sites include the BBC, The Guardian, The New York Times, The Wall Street Journal, and the Washington Post.

Flying cars and smart mirrors: Among the Internet of Things trends to look for in 2020 are flying cars and mirrors that deliver news and weather while you’re brushing your hair, What Mobile says. Widespread use of flying cars may be a way off, but one startup is working on them. Multilingual voice assistants and flexible displays are other things to watch for.

Supporting the latest version of the Privacy Pass Protocol

Supporting the latest version of the Privacy Pass Protocol

At Cloudflare, we are committed to supporting and developing new privacy-preserving technologies that benefit all Internet users. In November 2017, we announced server-side support for the Privacy Pass protocol, a piece of work developed in collaboration with the academic community. Privacy Pass, in a nutshell, allows clients to provide proof of trust without revealing where and when the trust was provided. The aim of the protocol is then to allow anyone to prove they are trusted by a server, without that server being able to track the user via the trust that was assigned.

On a technical level, Privacy Pass clients receive attestation tokens from a server, that can then be redeemed in the future. These tokens are provided when a server deems the client to be trusted; for example, after they have logged into a service or if they prove certain characteristics. The redeemed tokens are cryptographically unlinkable to the attestation originally provided by the server, and so they do not reveal anything about the client.

To use Privacy Pass, clients can install an open-source browser extension available in Chrome & Firefox. There have been over 150,000 individual downloads of Privacy Pass worldwide; approximately 130,000 in Chrome and Continue reading

Whitebox Hardware and Open-Source Software

One of my subscribers was interested in trying out whitebox solutions. He wrote:

What open source/whitebox software/hardware should I look at if I wanted to build a leaf-and-spine VXLAN/EVPN/BGP data center.

I don’t think you can get a fully-open-source solution because the ASIC manufacturers hide their SDK behind a mountain of NDAs (that strategy must make perfect sense – after all, it generated such awesome PR for NVIDIA). Anyway, the closest you can get (AFAIK) if you're a mere mortal is Cumulus Linux, and you just choose any whitebox hardware off their Hardware Compatibility List.

Object storage in the cloud: Is backup needed?

The failure to back up data that is stored in a cloud block-storage service can be lost forever if not properly backed up. This article explains how object storage works very differently from block storage and how it offers better built-in protections.What is Object Storage? Each cloud vendor offers an object storage service, and they include Amazon's Simple Storage Service (S3), Azure’s Blob Store, and Google’s Cloud Storage.Think of object storage systems like a file system with no hierarchical structure of directories and subdirectories. Where a file system uses a combination of a directory structure and file name to identify and locate a file, every object stored in an object storage system gets a unique identifier (UID) based on its content.To read this article in full, please click here
