Browser Isolation for teams of all sizes

Every Internet-connected organization relies on web browsers to operate: accepting transactions, engaging with customers, or working with sensitive data. The very act of clicking a link triggers your web browser to download and execute a large bundle of unknown code on your local device.

IT organizations have always been on the back foot while defending themselves from security threats. It is not a question of ‘if’, but ‘when’ the next zero-day vulnerability will compromise a web browser. How can IT organizations protect their users and data from unknown threats without over-blocking every potential risk? The solution is to shift the burden of executing untrusted code from the user’s device to a remote isolated browser.

Bringing Remote Browser Isolation to teams of any size

Today we are excited to announce that Cloudflare Browser Isolation is now available within Cloudflare for Teams suite of zero trust security and secure web browsing services as an add-on. Teams of any size from startups to large enterprises can benefit from reliable and safe browsing without changing their preferred web browser or setting up complex network topologies.

Remote Browsers must be reliable

Running sensitive workloads in secure environments is nothing new, and Remote Browser Isolation (RBI) Continue reading

New device security partnerships for Cloudflare One

Last October, we announced Cloudflare One, our comprehensive, cloud-based network-as-a-service solution that is secure, fast, reliable, and defines the future of the corporate network. Cloudflare One consists of two components: network services like Magic WAN and Magic Transit that protect data centers and branch offices and connect them to the Internet, and Cloudflare for Teams, which secures corporate applications, devices, and employees working on the Internet. Today, we are excited to announce new integrations with VMware Carbon Black, CrowdStrike, and SentinelOne to pair with our existing Tanium integration. Cloudflare for Teams customers can now use these integrations to restrict access to their applications based on security signals from their devices.

Protecting applications with Cloudflare for Teams

When the COVID-19 pandemic unfolded, many of us started to work remotely. Employees left the office, but the network and applications they worked with didn’t. VPNs quickly began folding under heavy load from backhauling traffic and reconfiguring firewalls became an overnight IT nightmare.

This has accelerated many organizations' timelines for adopting a Zero Trust based network architecture. Zero Trust means to mistrust every connection request to a corporate resource, and instead intercept and only grant access if criteria defined by an administrator are Continue reading

Announcing antivirus in Cloudflare Gateway

Today we’re announcing support for malware detection and prevention directly from the Cloudflare edge, giving Gateway users an additional line of defense against security threats.

Cloudflare Gateway protects employees and data from threats on the Internet, and it does so without sacrificing performance for security. Instead of backhauling traffic to a central location, Gateway customers connect to one of Cloudflare’s data centers in 200 cities around the world where our network can apply content and security policies to protect their Internet-bound traffic.

Last year, Gateway expanded from a secure DNS filtering solution to a full Secure Web Gateway capable of protecting every user’s HTTP traffic as well. This enables admins to detect and block not only threats at the DNS layer, but malicious URLs and undesired file types as well. Moreover, admins now have the ability to create high-impact, company-wide policies that protect all users with one click, or they can create more granular rules based on user identity.

Earlier this month, we launched application policies in Cloudflare Gateway to make it easier for administrators to block specific web applications. With this feature, administrators can block those applications commonly used to distribute malware, such as public cloud file storage.

Anatomy of a Targeted Ransomware Attack

Imagine your most critical systems suddenly stop operating, bringing your entire business to a screeching halt. And then someone demands a ransom to get your systems working again. Or someone launches a DDoS against you and demands ransom to make it stop.  That’s the world of ransomware and ransom DDoS.

So what exactly is ransomware? It is malicious software that encrypts files on computers making them useless until they are decrypted. In some cases, ransomware could even corrupt and destroy data. A ransom note is then placed on compromised systems with instructions to pay a ransom in exchange for a decryption utility that can be used to restore encrypted files. Payment is often in the form of Bitcoin or other cryptocurrency.

Recently, Cloudflare onboarded and protected a Fortune 500 customer from a targeted Ransom DDoS (RDDoS) attack -- a different type of extortion attack.

Prior to joining Cloudflare, I responded to and investigated a large number of data breaches and ransomware attacks for clients across various industries, including healthcare, financial, and education, to name a few. I’ve been in the trenches analyzing these types of attacks and working closely with clients to help them recover from the aftermath.

Unequal-Cost Multipath in Link State Protocols

TL&DR: You get unequal-cost multipath for free with distance-vector routing protocols. Implementing it in link state routing protocols is an order of magnitude more CPU-consuming.

Continuing our exploration of the Unequal-Cost Multipath world, why was it implemented in EIGRP decades ago, but not in OSPF or IS-IS?

Ignoring for the moment the “does it make sense” dilemma: finding downstream paths (paths strictly shorter than the current best path) is a side effect of running distance vector algorithms.

Measuring ROAs and ROV

In 2020 APNIC Labs set up a measurement system for the validators. What we were trying to provide was a detailed view of where invalid routes were being propagated, and also take a longitudinal view of how things are changing over time. The report is at https://stats.labs.apnic.net/rpki and the description of the measurement is at https://www.potaroo.net/ispcol/2020-06/rov.html. I'd like to update this description with some work we’ve done on this measurement platform in recent months.

How to Implement the Principle of Least Privilege With CloudFormation StackSets

AWS CloudFormation is a service that lets you create a collection of related Amazon Web Services and third-party resources and provision them in an orderly and predictable fashion. A typical access control pattern is to delegate permissions for users to interact with CloudFormation and remove or limit their permissions to provision resources directly. You can grant the AWS CloudFormation service permission to create resources by creating a role that the user passes to CloudFormation when a stack or stack set is created. This can be used to ensure that only pre-authorized services and resources are provisioned in your AWS account. In this post, I show you how to conform to the principle of least privilege while still allowing users to use CloudFormation to create the resources they need.

Google Says The SOC Is The New Motherboard

For two decades now, Google has demonstrated perhaps more than any other company that the datacenter is the new computer, what the search engine giant called a “warehouse-scale machine” way back in 2009 with a paper written by Urs Hölzle, who was and still is senior vice president for Technical Infrastructure at Google, and Luiz André Barroso, who is vice president of engineering for the core products at Google and who was a researcher at Digital Equipment and Compaq before that. …

Google Says The SOC Is The New Motherboard was written by Timothy Prickett Morgan at The Next Platform.

New Tech Skills In Two Hours

How long does it take to learn a new skill? It’s like…a really long time, right? You never have that much time to learn whatever it is. Most people who learn new skills are dedicated super humans who put in 25 hour days doing labs and reading books and taking courses and sniffing markers. Those folks sacrifice everything to stay ahead and command the respect of their peers. Right? Isn’t that how it’s supposed to work?

Don’t overthink it.

New skills come from one thing. Focus. That’s it. That’s the secret. Focus to learn a skill comes in blocks of a few undistracted hours at a time. Not dramatic sacrifice. Not bragging to social media about how you’re crushing it on your studies because you’ve given up your personal life.

Let the public drama queen masochists do what they feel they must to impress…whomever. They are not your role model. You don’t need to be them. You just need to find a few consecutive hours on your calendar. Block them off. Use them to focus on a single thing you want to learn. During the blocked off time, learn the thing. Do not do any of the other things that Continue reading
