What to Look for When Choosing a VPN

We welcome this guest post from Top10VPN.com, an Organization Member of the Internet Society.

The search for online privacy has driven a quarter of the world’s Internet users to download a Virtual Private Network (VPN). VPN services are now an important tool for anyone concerned about security and privacy on public networks.

There’s a world of difference between VPNs, though. Without clear and unbiased information many users are forced to navigate their choice of VPN without much clarity.

Why is choosing the right VPN provider so important?

Whenever you switch on a VPN you are entrusting its provider with your personal data, browsing activity, and sometimes even your security. For this reason, VPN providers must be held to a higher standard than most products. It’s important you do your due diligence when making a decision.

What should I look out for? 

A good VPN will ensure that no one – even the VPN itself – can see what the user is doing online. Consider the following qualities:

Technical Security

The most secure VPN services will be transparent about the measures they have in place to safeguard their users and their business.

Any VPN worth its salt will offer Continue reading

IDG Contributor Network: The evolution to Secure Access Service Edge (SASE) is being driven by necessity

The WAN consists of network and security stacks, both of which have gone through several phases of evolution. Initially, we began with the router, introduced WAN optimization, and then edge SD-WAN. From the perspective of security, we have a number of firewall generations that lead to network security-as-a-service. In today’s scenario, we have advanced to another stage that is more suited to today’s environment. This stage is the convergence of network and security in the cloud.For some, the network and security trends have been thought of in terms of silos. However, the new market category of secure access service edge (SASE) challenges this ideology and recommends a converged cloud-delivered secure access service edge.To read this article in full, please click here

Who DDoS’d Austin?

Who DDoS'd Austin?

It was a scorching Monday on July 22 as temperatures soared above 37°C (99°F) in Austin, TX, the live music capital of the world. Only hours earlier, the last crowds dispersed from the historic East 6th Street entertainment district. A few blocks away, Cloudflarians were starting to make their way to the office. Little did those early arrivers know that they would soon be unknowingly participating in a Cloudflare time honored tradition of dogfooding new services before releasing them to the wild.

(A photo I took on a night out with the team while visiting the Cloudflare Austin office)

Dogfooding is when an organization uses its own products. In this case, we dogfed our newest cloud service, Magic Transit, which both protects and accelerates our customers’ entire network infrastructure—not just their web properties or TCP/UDP applications. With Magic Transit, Cloudflare announces your IP prefixes via BGP, attracts (routes) your traffic to our global network edge, blocks bad packets, and delivers good packets to your data centers via Anycast GRE.

Who DDoS'd Austin?

We decided to use Austin’s network because we wanted to test the new service on a live network with real traffic from real people and apps. Continue reading

Master the Alternate "Public Cloud Networking" Universe

You probably heard me say “networking engineer encountering a public cloud feels like Alice in Wonderland” - packet forwarding works in a different way in every public cloud, subnets are a mix between routed interfaces and VRFs, you cannot change IP addresses without involving the orchestration system…

We covered the networking aspects of Amazon Web Services and Azure in our cloud webinars, but you might need a bigger picture:

How IT pros deal with SD-WAN security concerns

SD-WAN technology is becoming increasingly popular because it's less expensive, more flexible and easier to deploy than MPLS, it provides centralized visibility and management, and it boosts the overall performance of WAN links, which makes employees more productive. But enabling end users in branch offices to connect directly to the public internet and to cloud services raises serious security concerns, which adds another level of complexity and risk to an SD-WAN rollout. To read this article in full, please click here(Insider Story)

Securing open source: a brief look at dependency management

Taking full advantage of all that IT automation and orchestration have to offer frequently involves combining IT infrastructure automation with in-house application development. To this end, open source software is often used to speed development. Unfortunately, incorporating third-party software into your application means incorporating that third-party software’s vulnerabilities, too.

Scanning for, identifying, and patching open source dependencies in an application’s codebase is known as dependency management, and it’s increasingly considered a critical part of modern development. A recent report found that 60% of open source programs audited had a vulnerability that’s already been patched. With 96% of all code using open source libraries, this is a problem that impacts everyone.

There are many dependency management products available; too many to list in a single blog post. That said, we’ll look at some examples of well-known dependency management products that fall into three broad categories: free, open source software; commercial software with a free tier; and commercial software without a free tier.

Some dependency management products rely on open source vulnerability lists (the most famous of which is supplied by the National Institute of Standards and Technology [NIST]). Some products are commercial, and use closed databases (often in combination with the Continue reading

41 – Interconnecting Traditional DCs with DCNM using VXLAN EVPN Multi-site

Good day,

The same question arises often about how to leverage DCNM to deploy a VXLAN EVPN Multi-site between traditional Data Centers. To clarify, DCNM can definitively help interconnecting two or multiple Classical Ethernet-based DC networks, in a short time.

As a reminder (post 37) , VXLAN EVPN Multi-site overlay is initiated from the Border Gateway nodes (BGW). The BGW function can run in two different modes; either in Anycast BGW mode (Up to 6 BGW devices per site), traditionally deployed to interconnect VXLAN EVPN based fabrics, or in vPC BGW mode (up to 2 BGW per site), essentially designed to interconnect traditional data centers, but not limited to. vPC BGW can be leveraged to interconnect multiple VXLAN EVPN fabrics from which Endpoints can be locally dual- attached at layer 2. Several designations are used to describe the Classic Ethernet-based data center networks such as Traditional or legacy data center network. All these terms mean that these network are non VXLAN EVPN-based fabrics. The vPC BGW node is agnostic about data center network types, models or switches that construct the data center infrastructure, as long as it offers Layer 2 (dot1Q) connectivity for layer 2 extension, and if Continue reading

Google claims quantum supremacy over supercomputers

The results of an experiment performed on Google’s Sycamore quantum computer demonstrate that theoretical quantum computing designs can work as expected, the company announced today in a paper published in the journal Nature.Formulating the problem was the first hurdle. The company’s research team eventually settled on comparing the Sycamore computer’s output to that of a modern, classical supercomputer in the task of reading the state of a pseudo-random quantum circuit. This results in a computational challenge that should be comparatively simple for Sycamore, but enormously difficult for a supercomputer equipped with traditional silicon.To read this article in full, please click here
