Cloudflare Radar 2022 Year in Review

In 2022, with nearly five billion people around the world (as well as an untold number of “bots”) using the Internet, analyzing aggregate data about this usage can uncover some very interesting trends. To that end, we’re excited to present the Cloudflare Radar 2022 Year In Review, featuring interactive charts, graphs, and maps you can use to explore notable Internet trends observed throughout this past year. The Year In Review website is part of Cloudflare Radar, which celebrated its second birthday in September with the launch of Radar 2.0.

We have organized the trends we observed around three different topic areas: Traffic, Adoption, and Security. The content covered within each of these areas is described in more detail in their respective sections below. Building on the 2021 Year In Review, we have incorporated several additional metrics this year, and have also improved the underlying methodology. (As such, the charts are not directly comparable to develop insights into year-over-year changes.)

Website visualizations shown at a weekly granularity cover the period from January 2 through November 26, 2022 (the start of the first full week of the year through the end of the last full Continue reading

What is Zero Trust Network Architecture (ZTNA)?

Zero Trust is a term coined by John Kindervag while he was an analyst at Forrester Research to describe a strategic framework in which nothing on the network is trusted by default – not devices, not end users, not processes. Everything must be authenticated, authorized, verified and continuously monitored.The traditional approach to security was based on the concept of “trust, but verify.” The weakness of this approach is that once someone was authenticated, they were considered trusted and could move laterally to access sensitive data and systems that should have been off-limits.Zero Trust principles change this to “never trust, always verify.” A Zero Trust architecture doesn’t aim to make a system trusted or secure, but rather to eliminate the concept of trust altogether. Zero Trust security models assume that an attacker is present in the environment at all times. Trust is never granted unconditionally or permanently, but must be continually evaluated.To read this article in full, please click here

Using the ss command on Linux to view details on sockets

The ss command is used to dump socket statistics on Linux systems. It serves as a replacement for the netstat command and is often used for troubleshooting network problems.What is a socket? To make the best use of the ss command, it’s important to understand what a socket is. A socket is a type of pseudo file (i.e., not an actual file) that represents a network connection. A socket identifies both the remote host and the port that it connects to so that data can be sent between the systems. Sockets are similar to pipes except that pipes only facilitate connections between processes on the same system where sockets work on the same or different systems. Unlike pipes, sockets also provide bidirectional communication.To read this article in full, please click here

Handwashing Techniques to Teach Your Employees

National handwashing awareness week is an annual event celebrated in December to focus on the importance of proper hand hygiene and general health. It is designed to remind everyone that clean hands can help prevent illness, disease, and the spread of germs. Encouraging hand hygiene among your employees is essential for workplace safety. Teaching handwashing techniques can help provide an extra layer of protection, lessen the spread of germs, and show employees that you care about their health and well-being. To ensure hand hygiene at work, here’s what you should teach your employees:

Use warm water and soap when washing hands

Warm water helps to remove more dirt, oils, and germs from the skin than cold water. Employees should use hot water if it’s available and always make sure to wet their hands with clean running water before applying soap. All surfaces of the hands should be washed thoroughly, including the backs of the hands, wrists, between fingers, and under fingernails.

Scrub for at least 20 seconds

After wetting their hands with clean running water, employees should apply soap and lather up their hands while scrubbing them together in a back-and-forth motion for at least 20 seconds. This includes scrubbing Continue reading

One of our most requested features is here: DNS record comments and tags

Starting today, we’re adding support on all zone plans to add custom comments on your DNS records. Users on the Pro, Business and Enterprise plan will also be able to tag DNS records.

DNS records are important

DNS records play an essential role when it comes to operating a website or a web application. In general, they are used to mapping human-readable hostnames to machine-readable information, most commonly IP addresses. Besides mapping hostnames to IP addresses they also fulfill many other use cases like:

• Ensuring emails can reach your inbox, by setting up MX records.
• Avoiding email spoofing and phishing by configuring SPF, DMARC and DKIM policies as TXT records.
• Validating a TLS certificate by adding a TXT (or CNAME) record.
• Specifying allowed certificate authorities that can issue certificates on behalf of your domain by creating a CAA record.
• Validating ownership of your domain for other web services (website hosting, email hosting, web storage, etc.) - usually by creating a TXT record.
• And many more.

With all these different use cases, it is easy to forget what a particular DNS record is for and it is not always possible to derive the purpose from the name, type and Continue reading

How to build a service mesh with Istio and Calico

Microservices are loosely coupled software that provides flexibility and scalability to a cloud environment. However, securing this open architecture from vulnerabilities and malicious actors can be challenging without a service mesh.

This blog post will demonstrate how you can create an Istio and Calico integration to establish a service mesh that will manipulate HTTP traffic in the application layer. This Istio-Calico integration provides a unified way to write security policies interacting with applications and implement restrictions without disturbing the entire system.

What’s a service mesh?

A service mesh is a software layer that sits between the microservices that form your workload. After deploying and enabling a service mesh system for your workloads, an injector will add a sidecar container to each. These sidecars then collect and manipulate information via the rules you provide, allowing you to secure your cluster on an application level without requiring any change inside your software.

Without a service mesh, to ensure communication integrity and confidentiality between workloads, you must modify each to embed encryption methods. On top of that, gathering insight into the events that are happening in the application layer will require modifying the workload application itself, which all requires a good amount of Continue reading

More work for admins: When labor-saving management tools don’t ease workloads

If not deployed properly, today’s whiz-bang network management tools wind up making more work for network admins rather than saving them time and reducing their overload.Wait, labor saving devices don’t save labor? Not really, at least when it comes to freeing up time for more important or rewarding activities.It’s not unlike the "labor saving appliance" revolution in the American home, especially in the post-WW2 era.I’m referring, of course, to Ruth Schwartz Cowan’s classic history of technology book, More Work for Mother, which explored in depth how various supposedly labor-saving advances in household technology did not reduce the amount of time those women who kept house spent on housekeeping. On the contrary, because they mainly mechanized or automated work previously done by servants, children, or (occasionally) men, these tech advances shifted women’s efforts from organizing such work to doing it. At the same time, with some kinds of work around food preparation and clothes washing, they also brought back “in-house” work that had been effectively outsourced to commercial laundries, bakeries, etc.To read this article in full, please click here
