What is Wi-Fi 7, and will it replace wired Ethernet?

New Wi-Fi standards appear in such rapid succession that it’s often difficult to evaluate the differences between Wi-Fi 5, Wi-Fi 6, and Wi-Fi 6E—all of which are standards adopted in commercial products. And now there’s Wi-Fi 7.Chinese networking-equipment vendor H3C has released what it says is a Wi-Fi 7 router even though the Wi-Fi 7 standard isn’t expected to be finalized until 2024.What is Wi-Fi 7? Wi-Fi 7 or 802.11be is the next Wi-Fi standard being worked on by the Institute of Electrical and Electronics Engineers that promises speeds of a whopping 46Gbps, nearly five times faster than Wi-Fi 6, as well as reduced latency. Wi-Fi 7 (also known as Extremely High Throughput) is expected to deliver higher spectrum efficiency, higher power efficiency, better interference mitigation, higher capacity density, and higher cost efficiency. To read this article in full, please click here

What is Liposomal Curcumin (and How Can It Help You Live a Better Life?)

Liposomal curcumin is a powerful anti-inflammatory that has been shown to be effective in a wide range of inflammatory diseases. It is also a potent antioxidant and has been shown to protect cells from damage caused by oxidative stress.

Liposomal curcumin is thought to be more effective than regular curcumin because it is better absorbed by the body. One study showed that liposomal curcumin was absorbed into the bloodstream four times better than regular curcumin.

Liposomal curcumin has been shown to be effective in treating inflammatory diseases such as arthritis, Crohn’s disease, and ulcerative colitis. It is also thought to be helpful in managing symptoms of Alzheimer’s disease and other forms of dementia.

How does it work?

Liposomal curcumin works by inhibiting the production of inflammatory molecules called cytokines. It is also a powerful antioxidant and protects cells from damage caused by oxidative stress.

Benefits of Liposomal Curcumin

There are many potential benefits of liposomal curcumin. Some of the most well-studied benefits include:

Reduced inflammation

Announcing support for WASI on Cloudflare Workers

Today, we are announcing experimental support for WASI (the WebAssembly System Interface) on Cloudflare Workers and support within wrangler2 to make it a joy to work with. We continue to be incredibly excited about the entire WebAssembly ecosystem and are eager to adopt the standards as they are developed.

A Quick Primer on WebAssembly

So what is WASI anyway? To understand WASI, and why we’re excited about it, it’s worth a quick recap of WebAssembly, and the ecosystem around it.

WebAssembly promised us a future in which code written in compiled languages could be compiled to a common binary format and run in a secure sandbox, at near native speeds. While WebAssembly was designed with the browser in mind, the model rapidly extended to server-side platforms such as Cloudflare Workers (which has supported WebAssembly since 2017).

WebAssembly was originally designed to run alongside Javascript, and requires developers to interface directly with Javascript in order to access the world outside the sandbox. To put it another way, WebAssembly does not provide any standard interface for I/O tasks such as interacting with files, accessing the network, or reading the system clock. This means if you want to respond to an event from Continue reading

New WAF intelligence feeds

Cloudflare is expanding our WAF’s threat intelligence capabilities by adding four new managed IP lists that can be used as part of any custom firewall rule.

Managed lists are created and maintained by Cloudflare and are built based on threat intelligence feeds collected by analyzing patterns and trends observed across the Internet. Enterprise customers can already use the Open SOCKS Proxy list (launched in March 2021) and today we are adding four new IP lists: “VPNs”, “Botnets, Command and Control Servers”, “Malware” and “Anonymizers”.

Customers can reference these lists when creating a custom firewall rule or in Advanced Rate Limiting. For example, you can choose to block all traffic generated by IPs we categorize as VPNs, or rate limit traffic generated by all Anonymizers. You can simply incorporate managed IP lists in the powerful firewall rule builder. Of course, you can also use your own custom IP list.

Where do these feeds come from?

These lists are based on Cloudflare-generated threat feeds which Continue reading

Taking Automation to the Next Level: Using Ansible + GitOps to Manage the Lifecycle of a Containerized Application

One of the great advantages of combining GitOps with Ansible is that you get to streamline the automation delivery and the lifecycle of a containerized application.

With the abilities of GitOps we get to:

• Standardize configurations of our applications.
• Inherit the benefits of version control of our configurations.
• Easily track changes of the configuration settings making fixing issues easier.
• Have one source of truth for our applications.

Combine the above with Ansible and you have everything you need to accomplish configuration consistency for a containerized app anywhere that you automate. 

That leads us to, “how do we combine Ansible and GitOps to manage the lifecycle of a containerized application?”

Simple. By creating an Ansible workflow that is associated with a Git webhook that is part of my application’s repository.

What is a Git webhook you ask?

Git webhooks are defined as a method to deliver notifications to an external web server whenever certain actions occur on a repository.

For example, when a repository is updated, this could trigger an event that could trigger CI builds, deploy an environment, or in our case, modify the configuration of our containerized application. 

A webhook provides the ability to execute specified Continue reading

2022년 2분기 DDoS 공격 동향

2022년 2분기 DDoS 보고서에 오신 것을 환영합니다. 이 보고서에는 Cloudflare 네트워크 전반에서 관찰된 DDoS 위협 환경에 대한 인사이트와 동향이 담겨있습니다. 이 보고서의 인터랙티브 버전을 Radar에서도 이용할 수 있습니다.

2분기에 우리는 Cloudflare에서 자동으로 감지하고 대처한 초당 2,600만 회의 요청이 이루어진 HTTPS DDoS 공격을 포함하여 사상 최대 규모의 공격을 경험했습니다. 또한, 우크라이나와 러시아에 대한 공격은 지속되고 있으며, 새로운 랜섬 DDoS 공격이 등장하였습니다.

주요 특징

우크라이나와 러시아에서의 인터넷

• 지상에서의 전쟁은 정보 전파를 겨냥하는 공격과 함께 이루어집니다.
• 2분기에 가장 많은 DDoS 공격이 이루어진 대상은 우크라이나의 방송매체 회사들이었습니다. 실제로, 가장 많은 공격을 받은 상위 6개 산업은 모두 온라인/인터넷 매체, 출판, 방송 분야에 속했습니다.
• 반면, 러시아의 경우 온라인 매체는 가장 많은 공격을 받은 산업 순위에서 3위로 처집니다. 온라인 매체보다 순위가 높은 산업을 보면 러시아의 은행, 금융 서비스 및 보험(BFSI) 회사들이 2분기에 공격을 가장 많이 받았고, 전체 응용 프로그램 계층 DDoS 공격의 거의 50%가 BFSI 분야를 대상으로 했습니다. 두 번째로 공격을 많이 받은 것은 암호화폐 회사들이었습니다.

개방형 인터넷이 러시아로 계속 유입되도록 하고 공격이 외부로 유출되지 않도록 차단하기 위해 Cloudflare에서 어떤 일을 하는지 자세히 읽어보세요.

랜섬 DDoS 공격

• 우리는 팬시 라자러스(Fancy Lazarus)라고 자칭하는 공격자들에 의한 랜섬 DDoS 공격이 급증하는 것을 목격했습니다.
• 2022년 6월에는 랜섬 공격 건수가 올해 들어 최고 수준으로 늘어났습니다. DDoS 공격을 경험한 Continue reading
