Introducing Advanced DDoS Alerts

Introducing Advanced DDoS Alerts
Introducing Advanced DDoS Alerts

We’re pleased to introduce Advanced DDoS Alerts. Advanced DDoS Alerts are customizable and provide users the flexibility they need when managing many Internet properties. Users can easily define which alerts they want to receive — for which DDoS attack sizes, protocols and for which Internet properties.

This release includes two types of Advanced DDoS Alerts:

  1. Advanced HTTP DDoS Attack Alerts - Available to WAF/CDN customers on the Enterprise plan, who have also subscribed to the Advanced DDoS Protection service.
  2. Advanced L3/4 DDoS Attack Alerts - Available to Magic Transit and Spectrum BYOIP customers on the Enterprise plan.

Standard DDoS Alerts are available to customers on all plans, including the Free plan. Advanced DDoS Alerts are part of Cloudflare’s Advanced DDoS service.

Why alerts?

Distributed Denial of Service attacks are cyber attacks that aim to take down your Internet properties and make them unavailable for your users. As early as 2017, Cloudflare pioneered the Unmetered DDoS Protection to provide all customers with DDoS protection, without limits, to ensure that their Internet properties remain available. We’re able to provide this level of commitment to our customers thanks to our automated DDoS protection systems. But if the systems operate automatically, why even be Continue reading

Introducing Cloudflare Adaptive DDoS Protection – our new traffic profiling system for mitigating DDoS attacks

Introducing Cloudflare Adaptive DDoS Protection - our new traffic profiling system for mitigating DDoS attacks
Introducing Cloudflare Adaptive DDoS Protection - our new traffic profiling system for mitigating DDoS attacks

Every Internet property is unique, with its own traffic behaviors and patterns. For example, a website may only expect user traffic from certain geographies, and a network might only expect to see a limited set of protocols.

Understanding that the traffic patterns of each Internet property are unique is what led us to develop the Adaptive DDoS Protection system. Adaptive DDoS Protection joins our existing suite of automated DDoS defenses and takes it to the next level. The new system learns your unique traffic patterns and adapts to protect against sophisticated DDoS attacks.

Adaptive DDoS Protection is now generally available to Enterprise customers:

  • HTTP Adaptive DDoS Protection - available to WAF/CDN customers on the Enterprise plan, who have also subscribed to the Advanced DDoS Protection service.
  • L3/4 Adaptive DDoS Protection - available to Magic Transit and Spectrum customers on an Enterprise plan.

Adaptive DDoS Protection learns your traffic patterns

The Adaptive DDoS Protection system creates a traffic profile by looking at a customer’s maximal rates of traffic every day, for the past seven days. The profiles are recalculated every day using the past seven-day history. We then store the maximal traffic rates seen for every predefined dimension value. Every profile Continue reading

Account WAF now available to Enterprise customers

Account WAF now available to Enterprise customers
Account WAF now available to Enterprise customers

Do you manage more than a single domain? If the answer is yes, now you can manage a single WAF configuration for all your enterprise domains.

Cloudflare has been built around the concept of zone, which is broadly equivalent to a domain. Customers can add multiple domains to a Cloudflare account, and every domain has its own independent security configuration. If you deploy a rule to block bots on example.com, you will need to rewrite the same rule on example.org. You’ll then need to visit the dashboard of every zone when you want to update it. This applies to all WAF products including Managed, Firewall and Rate Limiting rules.

If you have just two domains that’s not a big deal. But if you manage hundreds or thousands of domains like most large organizations do. Dealing with individual domains becomes time-consuming, expensive or outright impractical. Of course, you could build automation relying on our API or Terraform. This will work seamlessly but not all organizations have the capabilities to manage this level of complexity. Furthermore, having a Terraform integration doesn’t fully replicate the experience or give the confidence provided by interacting with a well-designed UI.

Improved Access Control: Domain Scoped Roles are now generally available

Improved Access Control: Domain Scoped Roles are now generally available
Improved Access Control: Domain Scoped Roles are now generally available

Starting today, it is possible to scope your users’ access to specific domains with Domain Scoped Roles becoming generally available!

We are making it easier for account owners to manage their team’s access to Cloudflare by allowing user access to be scoped to individual domains. Ensuring users have the least amount of access they need and no more is critical, and Domain Scoped Roles is a major step in this direction. Additionally, with the use of Domain Groups, account owners can grant users access to a group of domains instead of individually. Domains can be added or removed from these groups to automatically update the access of those who have been granted access to the group. This reduces toil in managing user access.

One of the most common uses we have seen for Domain Scoped Roles is to limit access to production domains to a small set of team members, while still allowing development and pre-production domains to be open to the rest of the team. That way, someone can’t make changes to a production domain unless they are given access.

We are doing a rollout of this functionality across all Enterprise Cloudflare accounts, and you will receive an email Continue reading

How network engineers can get more sleep using Red Hat Ansible Automation Platform: Your guide to AnsibleFest 2022

Screen Shot 2022-09-07 at 11.09.29 AM

Since connectivity is critical to all types of business applications including cloud apps, managing and maintaining the network often falls into the overnight hours. This is great for the business, but it puts a large wrinkle in your work-life balance. Luckily, AnsibleFest is here to help you get more sleep! 

Continued use of an overnight network management work model can leave you wondering what other technology career options are available… which may mean that your team is smaller than it used to be due to turnover. Search LinkedIn jobs for “Ansible engineer” and you will find as many as 166,000 roles that ask for some form of Ansible skills. Udemy published the 2020 Workplace Learning Trends Report: The Skills of the Future that describes increased enthusiasm for learning technologies such as automation (page 20) and Cisco cites market research showing nearly 23% growth in network automation from 2022 to 2028. If you are in networking, automation can be very important to boost your career. 

Across networking domains, automation plays a key role in helping to balance working hours, so Ansible skills can be good to develop. Red Hat Ansible Automation Platform makes management and other tasks faster and Continue reading

Welcome to GA Week

Welcome to GA Week
Welcome to GA Week

Cloudflare ships a lot of products. Some of those products are shipped as beta, sometimes open, sometimes closed, and our huge customer base gives those betas an incredible workout. Making products work at scale, and in the heterogeneous environment of the real Internet is a challenge. We’re lucky to have so many enthusiastic customers ready to try out our betas.

And when those products exit beta they’re GA or Generally Available. This week you’ll be hearing a lot about products becoming GA.

But it’s not just about making products work and be available, it’s about making the best-of-breed. We ship early and iterate rapidly. We’ve done this over the years for WAF, DDoS mitigation, bot management, API protection, CDN and our developer platform. Today analyst firms such as Gartner, Forrester and IDC recognize us as leaders in all those areas.

That’s one reason we’re trusted by the likes of Broadcom, NCR, DHL Parcel, Panasonic, Canva, Shopify, L'Oréal, DoorDash, Garmin and more.

Over the years we’ve heard criticism that we’re the new kid on the block. The latest iteration of that is Zero Trust vendors seeing us as novices. It sounds all too familiar. It’s what the Continue reading

Weekend Reads 091622

Running a little late this week …


Smartphone shipments are forecast to shrink globally by 6.5 percent this year as many households feeling the pinch of inflation decide to prioritize paying for food, energy and other essentials over refreshing handsets.


SmartNICs have long been the domain of hyperscale and cloud datacenters, but they remain relatively uncommon in enterprise environments due in large part to the lack of software compatibility.


The last few years have demonstrated that breaches occur, no matter how much security organizations put in place.


Finally, one of the big challenges with subsea cabling has been power, and in particular how to provide power mid-cable for repeater equipment.


French cloud provider OVHcloud has opened up a Bring Your Own IP service, which it said allows customers to reuse existing public IPv4 blocks as failover addresses in the event of an outage.


Microsoft moves ahead with a plan to sunset basic authentication, and other providers are moving — or have moved — to requiring more secure authentication as well. Is your company ready?


You only have to follow cryptocurrency news casually to be struck by the size and frequency of cryptocurrency security failures.

Kubernetes 001. Building Cluster on Ubuntu Linux with Docker and Calico in 2022

Hello my friend,

The last Black Friday (in 2021) I’ve purchased some Kubernetes trainings from Linux Foundation with quite a huge discount. I’ve purchased and then has been doing nothing in their regard for quite a bit until I’ve received a notification in the beginning of the September that I have only 3 months to use the training and pass exam or it will expire. Moreover, I have 2 exams to pass, so… All my blogs for a bit will be dedicated to Kubernetes only, as I don’t have time to look into anything else for the time being. I will be using these blogs as a brain dump for me during preparation for CKA (Certified Kubernetes Administrator) and CKAD (Certified Kubernetes Application Developer). Whether I will manage it in 2,5 months, the time will show. Let’s get started.

Google Jupiter Data Center Network Fabric – New Way of Building Data Center Network Underlay

Google’s Datacenter Optical Circuit Switches and Jupiter network fabric Google’s data centers are unlike any other. It seems they have windows like normal houses because as from the last SIGCOMM’22 presentation, they took their SPINE switches and threw them right out of that window. Google worked on the Micro Electro Mechanical Systems (MEMS) for years in order to build an Optical Circuit Switch (OCS) that would enable dynamic reconfiguration of optical connections between switches in the data center. Optical Circuit Switch enables on-the-fly data center fabric aggregation block switch connections reconfiguration without the need for physical rewiring. And most interestingly, the

How Idit Levine’s Athletic Past Fueled Solo.io‘s Startup

How Idit Levine’s Athletic Past Fueled Solo.io‘s Startup “I was basically going to compete with all my international friends for two minutes without parents, without anything,” Levine said. “I think it made me who I am today. It’s really giving you a lot of confidence to teach you how to handle situations … stay calm and still focus.” Developing that calm and focus proved an asset during Levine’s subsequent career in professional basketball in Israel, and when she later started her own company. In this episode of The Tech Founder Odyssey podcast series, Levine, founder and CEO of Colleen Coll and Heather Joslyn of The New Stack After finishing school and service in the Israeli Army, Levine was still unsure of what she wanted to do. She noticed her brother and sister’s fascination with computers. Soon enough, she recalled,  “I picked up a book to teach myself how to program.” Continue reading

Redundancy Is Not Resiliency

Most people carry a spare tire in their car. It’s there in case you get a flat and need to change the tire before you can be on your way again. In my old VAR job I drove a lot away from home and to the middle of nowhere so I didn’t want to rely on roadside assistance. Instead I just grabbed the extra tire out of the back if I needed it and went on my way. However, the process wasn’t entirely hitless. Even the pit crew for a racing team needs time to change tires. I could probably get it done in 20 minutes with appropriate cursing but those were 20 minutes that I wasn’t doing anything else beyond fixing a tire.

Spare tires are redundant. You have an extra thing to replace something that isn’t working. IT operations teams are familiar with redundant systems. Maybe you have a cold spare on the shelf for a switch that might go down. You might have a cold or warm data center location for a disaster. You could even have redundant devices in your enterprise to help you get back in to your equipment if something causes it to go Continue reading
