Eliminate VPN vulnerabilities with Cloudflare One

On January 19, 2024, the Cybersecurity & Infrastructure Security Agency (CISA) issued Emergency Directive 24-01: Mitigate Ivanti Connect Secure and Ivanti Policy Secure Vulnerabilities. CISA has the authority to issue emergency directives in response to a known or reasonably suspected information security threat, vulnerability, or incident. U.S. Federal agencies are required to comply with these directives.

Federal agencies were directed to apply a mitigation against two recently discovered vulnerabilities; the mitigation was to be applied within three days. Further monitoring by CISA revealed that threat actors were continuing to exploit the vulnerabilities and had developed some workarounds to earlier mitigations and detection methods. On January 31, CISA issued Supplemental Direction V1 to the Emergency Directive instructing agencies to immediately disconnect all instances of Ivanti Connect Secure and Ivanti Policy Secure products from agency networks and perform several actions before bringing the products back into service.

This blog post will explore the threat actor’s tactics, discuss the high-value nature of the targeted products, and show how Cloudflare’s Secure Access Service Edge (SASE) platform protects against such threats.

As a side note and showing the value of layered protections, Cloudflare’s WAF had proactively detected the Ivanti zero-day vulnerabilities and deployed emergency Continue reading

Simplifying how enterprises connect to Cloudflare with Express Cloudflare Network Interconnect

We’re excited to announce the largest update to Cloudflare Network Interconnect (CNI) since its launch, and because we’re making CNIs faster and easier to deploy, we’re calling this Express CNI. At the most basic level, CNI is a cable between a customer’s network router and Cloudflare, which facilitates the direct exchange of information between networks instead of via the Internet. CNIs are fast, secure, and reliable, and have connected customer networks directly to Cloudflare for years. We’ve been listening to how we can improve the CNI experience, and today we are sharing more information about how we’re making it faster and easier to order CNIs, and connect them to Magic Transit and Magic WAN.

Interconnection services and what to consider

Interconnection services provide a private connection that allows you to connect your networks to other networks like the Internet, cloud service providers, and other businesses directly. This private connection benefits from improved connectivity versus going over the Internet and reduced exposure to common threats like Distributed Denial of Service (DDoS) attacks.

Cost is an important consideration when evaluating any vendor for interconnection services. The cost of an interconnection is typically comprised of a fixed port fee, based on the Continue reading

Zero Trust WARP: tunneling with a MASQUE

Slipping on the MASQUE

In June 2023, we told you that we were building a new protocol, MASQUE, into WARP. MASQUE is a fascinating protocol that extends the capabilities of HTTP/3 and leverages the unique properties of the QUIC transport protocol to efficiently proxy IP and UDP traffic without sacrificing performance or privacy

At the same time, we’ve seen a rising demand from Zero Trust customers for features and solutions that only MASQUE can deliver. All customers want WARP traffic to look like HTTPS to avoid detection and blocking by firewalls, while a significant number of customers also require FIPS-compliant encryption. We have something good here, and it’s been proven elsewhere (more on that below), so we are building MASQUE into Zero Trust WARP and will be making it available to all of our Zero Trust customers — at WARP speed!

This blog post highlights some of the key benefits our Cloudflare One customers will realize with MASQUE.

Before the MASQUE

Cloudflare is on a mission to help build a better Internet. And it is a journey we’ve been on with our device client and WARP for almost five years. The precursor to WARP was the 2018 launch of Continue reading

Multiline Expressions in Ansible Playbooks

Another week, another Ansible quirk 🤷‍♂️ Imagine you have a long Jinja2 expression, and you want to wrap it into multiple lines to improve readability. Using multiline YAML format seems to be the ideal choice:

---
- name: Test playbook
  hosts: localhost
  tasks:
  - set_fact:
      a: >
        {{ 123 == 345 or
           123 > 345 }}

It works every time 50% of the time (this time depending on your Ansible version).

Secure your unprotected assets with Security Center: quick view for CISOs

We understand that one of the significant hurdles faced by our customers, especially larger organizations, is obtaining a clear view of the deployment of Cloudflare services throughout their vast and complex infrastructures. The question isn't just whether Cloudflare is deployed, but whether it's fully optimized across every asset and service. Addressing this challenge head-on, we're rolling out a new feature set designed to provide better visibility and control over your security posture.

The problem we are addressing

The core problem we're tackling is the growing complexity of cyber threats and the expanding attack surface, which complicates maintaining a strong security posture for our customers.

It's not uncommon for organizations to deploy a variety of security solutions, including ours, without fully optimizing and implementing their configurations. This results in a false sense of security, underutilized investments and, more critically, exposed vulnerabilities. Our customers frequently express concerns about not having a clear picture of their security posture across their entire infrastructure, uncertain if critical assets are adequately protected or if specific Cloudflare security features could be better leveraged.

We want to bring users comprehensive visibility into their security configurations and the state of their deployments across Cloudflare's suite of products. By providing Continue reading

Securing Cloudflare with Cloudflare: a Zero Trust journey

Cloudflare is committed to providing our customers with industry-leading network security solutions. At the same time, we recognize that establishing robust security measures involves identifying potential threats by using processes that may involve scrutinizing sensitive or personal data, which in turn can pose a risk to privacy. As a result, we work hard to balance privacy and security by building privacy-first security solutions that we offer to our customers and use for our own network.

In this post, we'll walk through how we deployed Cloudflare products like Access and our Zero Trust Agent in a privacy-focused way for employees who use the Cloudflare network. Even though global legal regimes generally afford employees a lower level of privacy protection on corporate networks, we work hard to make sure our employees understand their privacy choices because Cloudflare has a strong culture and history of respecting and furthering user privacy on the Internet. We’ve found that many of our customers feel similarly about ensuring that they are protecting privacy while also securing their networks.

So how do we balance our commitment to privacy with ensuring the security of our internal corporate environment using Cloudflare products and services? We start with the basics: We Continue reading

Simpler migration from Netskope and Zscaler to Cloudflare: introducing Deskope and a Descaler partner update

Today, Cloudflare is launching early access to the Deskope Program, a new set of tooling to help migrate existing Netskope customers to Cloudflare One for a faster and easier security experience. In addition, we’re also thrilled to announce the expansion of the Descaler Program to Authorized Service Delivery Partners, who will now have exclusive access to the Descaler toolkit to help customers move safely and quickly to Cloudflare.

Introducing Deskope — Migrate from Netskope to Cloudflare One

To set the stage, Cloudflare One is our Secure Access Service Edge (SASE) platform that combines network connectivity services with Zero Trust security on one of the fastest, most resilient, and most composable global networks. The Descaler Program was announced in early 2023 as a frictionless path to migrate existing Zscaler customers to Cloudflare One. Today, we are announcing the Deskope Program as a new and equally effortless path to migrate existing Netskope customers to Cloudflare One.

The Deskope Program follows the same approach as the Descaler process, including the tools, process, and partners you need for a frictionless technical migration. This program is completed through architecture workshops, technical migration tooling, and when requested, trusted partner engagements.

Deskope's approach is based on Continue reading

Protecting APIs with JWT Validation

Today, we are happy to announce that Cloudflare customers can protect their APIs from broken authentication attacks by validating incoming JSON Web Tokens (JWTs) with API Gateway. Developers and their security teams need to control who can communicate with their APIs. Using API Gateway’s JWT Validation, Cloudflare customers can ensure that their Identity Provider previously validated the user sending the request, and that the user’s authentication tokens have not expired or been tampered with.

What’s new in this release?

After our beta release in early 2023, we continued to gather feedback from customers on what they needed from JWT validation in API Gateway. We uncovered four main feature requests and shipped updates in this GA release to address them all:

Old, Beta limitation New, GA release capability
Only supported validating the raw JWT Support for the Bearer token format
Only supported one JWKS configuration Create up to four different JWKS configs to support different environments per zone
Only supported validating JWTs sent in HTTP headers Validate JWTs if they are sent in a cookie, not just an HTTP header
JWT validation ran on all requests to the entire zone Exclude any number of managed endpoints in a JWT validation rule

Announcing two highly requested DLP enhancements: Optical Character Recognition (OCR) and Source Code Detections

We are excited to announce two enhancements to Cloudflare’s Data Loss Prevention (DLP) service: support for Optical Character Recognition (OCR) and predefined source code detections. These two highly requested DLP features make it easier for organizations to protect their sensitive data with granularity and reduce the risks of breaches, regulatory non-compliance, and reputational damage:

  • With OCR, customers can efficiently identify and classify sensitive information contained within images or scanned documents.
  • With predefined source code detections, organizations can scan inline traffic for common code languages and block those HTTP requests to prevent data leaks, as well as detecting the storage of code in repositories such as Google Drive.

These capabilities are available now within our DLP engine, which is just one of several Cloudflare services, including cloud access security broker (CASB), Zero Trust network access (ZTNA), secure web gateway (SWG), remote browser isolation (RBI), and cloud email security, that help organizations protect data everywhere across web, SaaS, and private applications.

About Optical Character Recognition (OCR)

OCR enables the extraction of text from images. It converts the text within those images into readable text data that can be easily edited, searched, or analyzed, unlike images.

Sensitive data Continue reading

The state of the post-quantum Internet

Today, nearly two percent of all TLS 1.3 connections established with Cloudflare are secured with post-quantum cryptography. We expect to see double-digit adoption by the end of 2024. Apple announced in February 2024 that it will secure iMessage with post-quantum cryptography before the end of the year, and Signal chats are already secured. What once was the topic of futuristic tech demos will soon be the new security baseline for the Internet.

A lot has been happening in the field over the last few years, from mundane name changes (ML-KEM is the new name for Kyber), to new proposed algorithms in the signatures onramp, to the catastrophic attack on SIKE. Plenty that has been written merely three years ago now feels quite out of date. Thus, it is high time for an update: in this blog post we’ll take measure of where we are now in early 2024, what to expect for the coming years, and what you can do today.

Fraction of TLS 1.3 connections established with Cloudflare that are secured with post-quantum cryptography.
