This Blazing Fast VPN Is Now Available For Just $1/mo

If you use the internet (which you clearly do), you likely know how important it is to protect your data in an increasingly dangerous cyber environment. But like other essential tasks that tend to be tedious (like filing taxes early and brushing your teeth for the full two minutes), most installing and running a VPN can sound unappealing to many: sure, they encrypt your internet traffic and hide your location — but they can also run frustratingly slowly, delaying the way you’d usually use the internet for entertainment and work. That’s where Ivacy VPN is different: not only will the speedy service let you browse and stream lag-free, it also offers real-time threat detection technology, removing malware and viruses at the server level. It ensures that all your downloads and devices stay totally secure, so you can stay safe online without being inconvenienced.To read this article in full, please click here

History of the Internet: An Asian Perspective

Fun fact from this episode of the History of Networking: because of export rules, students in South Korea had to rebuild the TCP/IP stack for the PDP11 and other hosts in order to bring the first IP link up in southeastern Asia. In this recording, Donald and I are joined by Kilnam Chon.

Finding Common Ground on U.S. Net Neutrality

People in front of Washington monument

After more than a decade of regulatory ping pong, net neutrality’s future in the United States is still unclear.

Since 2004, FCC rulemakings have been caught in a vicious cycle. They have been passed, fought in court, and returned to the FCC with minor (and sometimes major) revisions. In the last few years there have also been numerous attempts to pass legislation, cementing net neutrality once and for all, but nothing has succeeded in Congress.

Recognizing the importance of finding a sustainable solution, the Internet Society proposed a collaborative process to help experts find common ground on this complex policy issue. Starting in June 2018, we convened an ideologically diverse group of experts to create a baseline set of principles for an open Internet. 

The Net Neutrality Experts’ Roundtable series included representatives from the technical community, edge providers, academia, Internet service providers, industry associations, and both left- and right-leaning civil society groups.

In a series of meetings over ten months, participants discussed how to create a sustainable solution for net neutrality that protect the interests of Internet users while fostering an environment that encourages investment and innovation. 

Ultimately, the group was able to create a consensus-driven set of bipartisan principles for an open Continue reading

Network monitoring in the hybrid cloud/multi-cloud era

Network monitoring in the enterprise has never been easy. Even before organizations began moving software and infrastructure to the cloud, a typical enterprise used four to 10 tools just to monitor and troubleshoot their own networks, according to analyst and consulting firm Enterprise Management Associates.The public cloud adds another complex wrinkle to network visibility. Traditional monitoring tools center around the health and performance of individual network elements. Today’s digital business era requires a more holistic view of networks with the ability to glean and correlate data from diverse cloud environments using big data analytics and machine learning. To read this article in full, please click here

IPv6 Support in Microsoft Azure

TL&DR: MIA

Six years ago, when I was talking about overlay virtual networks at Interop, I loved to joke that we must be living on a weird planet where Microsoft has the best overlay virtual networking implementation… at least as far as IPv6 goes.

Even then, their data plane implementation which was fully dual-stack-aware on both tenant- and underlay level was way ahead of what System Center could do.

With Cray buy, HPE rules but does not own the supercomputing market

Hewlett Packard Enterprise was already the leader in the high-performance computing (HPC) sector before its announced acquisition of supercomputer maker Cray earlier this month. Now it has a commanding lead, but there are still competitors to the giant.The news that HPE would shell out $1.3 billion to buy the company came just as Cray has announced plans to build three of the biggest systems yet – all exascale, and all at the same time for 2021 deployment.Sales had been slowing for HPC systems, but our government with its endless supply of money came to the rescue, throwing hundreds of millions at Cray for systems to be built at Lawrence Berkeley National Laboratory, Argonne National Laboratory, and Oak Ridge National Laboratory.To read this article in full, please click here

Create lab lessons for the NRE Labs Antidote network emulator

The Antidote network emulator, part of the Network Reliability Engineering project, offers a web interface that presents network emulation scenarios to users as documented lessons. Each lesson is presented in a window running Jupyter Notebooks and contains commands that the user can click on to run them on the virtual nodes in the network emulation scenario.

nrelabs lessons

The NRE Labs developers intend for Antidote to be used as an educational tool. Its lesson-focused user interface supports students’ learning progress. This post is a tutorial showing how to create and test two simple, but different, Antidote lessons.

Lab documentation

At the time I wrote this post, the Antidote documentation does not provide enough practical information about how to create new Antidote labs. However, useful information is spread around in a few different locations, which I list below:

BrandPost: Moving to the Cloud? SD-WAN Matters!

This is the first in a two-part blog series that will explore how enterprises can realize the full transformation promise of the cloud by shifting to a business first networking model powered by a business-driven SD-WAN. The focus for this installment will be on automating secure IPsec connectivity and intelligently steering traffic to cloud providers. Over the past several years we’ve seen a major shift in data center strategies where enterprise IT organizations are shifting applications and workloads to cloud, whether private or public. More and more, enterprises are leveraging software as-a-service (SaaS) applications and infrastructure as-a-service (IaaS) cloud services from leading providers like Amazon AWS, Google Cloud, Microsoft Azure and Oracle Cloud Infrastructure. This represents a dramatic shift in enterprise data traffic patterns as fewer and fewer applications are hosted within the walls of the traditional corporate data center. To read this article in full, please click here

Stopping SharePoint’s CVE-2019-0604

Stopping SharePoint’s CVE-2019-0604

On Saturday, 11th May 2019, we got the news of a critical web vulnerability being actively exploited in the wild by advanced persistent threats (APTs), affecting Microsoft’s SharePoint server (versions 2010 through 2019).

This was CVE-2019-0604, a Remote Code Execution vulnerability in Microsoft SharePoint Servers which was not previously known to be exploitable via the web.

Several cyber security centres including the Canadian Centre for Cyber Security and Saudi Arabia’s National Center put out alerts for this threat, indicating it was being exploited to download and execute malicious code which would in turn take complete control of servers.

The affected software versions:

  • Microsoft SharePoint Foundation 2010 Service Pack 2
  • Microsoft SharePoint Foundation 2013 Service Pack 1
  • Microsoft SharePoint Server 2010 Service Pack 2
  • Microsoft SharePoint Server 2013 Service Pack 1
  • Microsoft SharePoint Enterprise Server 2016
  • Microsoft SharePoint Server 2019

Introduction

The vulnerability was initially given a critical CVSS v3 rating of 8.8 on the Zero Day Initiative advisory (however the advisory states authentication is required). This would imply only an insider threat, someone who has authorisation within SharePoint, such as an employee, on the local network could exploit the vulnerability.

We discovered that was not always Continue reading
