Over the last several years, both Area 1 and Cloudflare built pipelines for ingesting threat indicator data, for use within our products. During the acquisition process we compared notes, and we discovered that the overlap of indicators between our two respective systems was smaller than we expected. This presented us with an opportunity: as one of our first tasks in bringing the two companies together, we have started bringing Area 1’s threat indicator data into the Cloudflare suite of products. This means that all the products today that use indicator data from Cloudflare’s own pipeline now get the benefit of Area 1’s data, too.
Area 1 built a data pipeline focused on identifying new and active phishing threats, which now supplements the Phishing category available today in Gateway. If you have a policy that references this category, you’re already benefiting from this additional threat coverage.
Cloudflare is able to combine the data, procedures and techniques developed independently by both the Cloudflare team and the Area 1 team prior to acquisition. Customers are able to benefit from the work of both teams across the suite of Cloudflare products.

Last week’s IPv6 security video introduced the rogue IPv6 RA challenges and the usual countermeasure – RA guard. Unfortunately, IPv6 tends to be a wonderfully extensible protocol, creating all sorts of opportunities for nefarious actors and security researchers.
For years, the networking vendors were furiously trying to plug the holes created by the academically minded IPv6 designers in love with fragmented extension headers. In the meantime, security researches had absolutely no problem finding yet another weird combination of IPv6 headers that would bypass any IPv6 RA guard implementation until IETF gave up and admitted one cannot have “infinitely extensible” and “secure” in the same sentence.
For more details watch the video by Christopher Werny describing how one could use IPv6 extension headers to circumvent IPv6 RA guard

Last week, Cloudflare automatically detected and mitigated a 26 million request per second DDoS attack — the largest HTTPS DDoS attack on record.
The attack targeted a customer website using Cloudflare’s Free plan. Similar to the previous 15M rps attack, this attack also originated mostly from Cloud Service Providers as opposed to Residential Internet Service Providers, indicating the use of hijacked virtual machines and powerful servers to generate the attack — as opposed to much weaker Internet of Things (IoT) devices.
Over the past year, we’ve witnessed one record-breaking attack after the other. Back in August 2021, we disclosed a 17.2M rps HTTP DDoS attack, and more recently in April, a 15M rps HTTPS DDoS attack. All were automatically detected and mitigated by our HTTP DDoS Managed Ruleset which is powered by our autonomous edge DDoS protection system.
The 26M rps DDoS attack originated from a small but powerful botnet of 5,067 devices. On average, each node generated approximately 5,200 rps at peak. To contrast the size of this botnet, we’ve been tracking another much larger but less powerful botnet of over 730,000 devices. The latter, larger botnet wasn’t able to generate more than one Continue reading
IPv6 security-focused presentations were usually an awesome opportunity to lean back and enjoy another round of whack-a-mole, often starting with an attacker using IPv6 Router Advertisements to divert traffic (see also: getting bored at Brussels airport) .
Rogue IPv6 RA challenges and the corresponding countermeasures are thus a mandatory part of any IPv6 security training, and Christopher Werny did a great job describing them in IPv6 security webinar.

Today we’re announcing Private Access Tokens, a completely invisible, private way to validate that real users are visiting your site. Visitors using operating systems that support these tokens, including the upcoming versions of macOS or iOS, can now prove they’re human without completing a CAPTCHA or giving up personal data. This will eliminate nearly 100% of CAPTCHAs served to these users.
What does this mean for you?
If you’re an Internet user:
If you’re a web or application developer:
If you’re a Cloudflare customer:

Today, a cluster of Internet standards were published that rationalize and modernize the definition of HTTP - the application protocol that underpins the web. This work includes updates to, and refactoring of, HTTP semantics, HTTP caching, HTTP/1.1, HTTP/2, and the brand-new HTTP/3. Developing these specifications has been no mean feat and today marks the culmination of efforts far and wide, in the Internet Engineering Task Force (IETF) and beyond. We thought it would be interesting to celebrate the occasion by sharing some analysis of Cloudflare's view of HTTP traffic over the last 12 months.
However, before we get into the traffic data, for quick reference, here are the new RFCs that you should make a note of and start using:
Information Security was one of the fields that Cisco systems used to, and still heavily participating.
Now a days not just information security, but cyber security as well, is a field that Cisco is going in and training many
of their engineers to profession.
The main difference summarizes the concept of both the domains, that is for information security, it is mainly
About securing the network components and assets from unauthorized access starting from physical access
Towards the control access, and by that it means accessing the nodes controlling the network, and affecting it.
Cyber security on the other hand is about protecting the same components from attacks, inside and outside attacks.
The attacks aim is usually either stealing sensitive data, or sabotage network components, or sometimes “both”.
Information Security wise, or IT Security wise, Cisco have been there for years, and they’ve been famous for their IT Security programs including the old obsolete CCNA Security, and the CCNP/CCIE Security programs that are still valid and refreshing till now a day.
Cyber Security wise, Cisco have evolved and developed their programs to present the CyberOps programs that includes the:
I recently talked to some security friends on a CloudBytes podcast recording that will be coming out in a few weeks. One of the things that came up was the idea of an air gapped system or network that represents the ultimate in security. I had a couple of thoughts that felt like a great topic for a blog post.
I can think of a ton of classical air gapped systems that we’ve seen in the media. Think about Mission: Impossible and the system that holds the NOC list:
Makes sense right? Totally secure unless you have Tom Cruise in your ductwork. It’s about as safe as you can make your data. It’s also about as inconvenient as you can make your data too. Want to protect a file so no one can ever steal it? Make it so no one can ever access it! Works great for data that doesn’t need to be updated regularly or even analyzed at any point. It’s offline for all intents and purposes.
Know what works great as an air gapped system? Root certificate authority servers. Even Microsoft agrees. So secure that you have to dig it out of storage Continue reading

Back in the early days of the Internet, you could physically see the hardware where your data was stored. You knew where your data was and what kind of locks and security protections you had in place. Fast-forward a few decades, and data is all “in the cloud”. Now, you have to trust that your cloud services provider is putting security precautions in place just as you would have if your data was still sitting on your hardware. The good news is, you don’t have to merely trust your provider anymore. There are a number of ways a cloud services provider can prove it has robust privacy and security protections in place.
Today, we are excited to announce that Cloudflare has taken three major steps forward in proving the security and privacy protections we provide to customers of our cloud services: we achieved a key cloud services certification, ISO/IEC 27018:2019; we completed our independent audit and received our Cloud Computing Compliance Criteria Catalog (“C5”) attestation; and we have joined the EU Cloud Code of Conduct General Assembly to help increase the impact of the trusted cloud ecosystem and encourage Continue reading
