Getting To The Root Of Security With Trusted Silicon
The increasingly distributed nature of computing and the rapid growth in the number of the small connected devices that make up the Internet of Things (IoT) are combining with trends like the rise of silicon-level vulnerabilities highlighted by Spectre, Meltdown, and more recent variants to create an expanding and fluid security landscape that’s difficult for enterprises to navigate. …

DeGrasse Tyson: Make Truth Great Again
Neil deGrasse Tyson tweets the following:I’m okay with a US Space Force. But what we need most is a Truth Force — one that defends against all enemies of accurate information, both foreign & domestic.— Neil deGrasse Tyson (@neiltyson) August 20, 2018
When people make comparisons with Orwell's "Ministry of Truth", he obtusely persists:
A good start: The National Academy of Sciences, which “…provides objective, science-based advice on critical issues affecting the nation."— Neil deGrasse Tyson (@neiltyson) August 20, 2018
Given that Orwellian dystopias were the theme of this summer's DEF CON hacker conference, let's explore what's wrong with this idea.
Truth vs. "Truth"
I work in a corrupted industry, variously known as the "infosec" community or "cybersecurity" industry. It's a great example of how truth is corrupted into "Truth".
At a recent government policy meeting, I pointed out how vendors often downplay the risk of bugs (vulnerabilities that can be exploited by hackers). When vendors are notified of these bugs and release a patch to fix them, they often give a risk rating. These ratings are often too low, in order to protect the corporate reputation. The representative from Oracle claimed that they didn't do Continue reading
Securing The Server, Inside And Out
Computing is hard enough, but the sophistication and proliferation of attacks on IT infrastructure, from the firewall moat surrounding the corporate network all the way down into the guts of the operating system kernel and deep into the speculative execution units on the physical processor, make the task of computing – with confidence – doubly difficult. …

How Cloudflare protects customers from cache poisoning
A few days ago, Cloudflare — along with the rest of the world — learned of a "practical" cache poisoning attack. In this post I’ll walk through the attack and explain how Cloudflare mitigated it for our customers. While any web cache is vulnerable to this attack, Cloudflare is uniquely able to take proactive steps to defend millions of customers.
In addition to the steps we’ve taken, we strongly recommend that customers update their origin web servers to mitigate vulnerabilities. Some popular vendors have applied patches that can be installed right away, including Drupal, Symfony, and Zend.
How a shared web cache works
Say a user requests a cacheable file, index.html. We first check if it’s in cache, and if it’s not not, we fetch it from the origin and store it. Subsequent users can request that file from our cache until it expires or gets evicted.
Although contents of a response can vary slightly between requests, customers may want to cache a single version of the file to improve performance:
(See this support page for more info about how to cache HTML with Cloudflare.)
How do we know it’s the same file? We create something Continue reading

Three new ways teams are using Cloudflare Access
Since leaving beta three weeks ago, Cloudflare Access has become our fastest-growing subscription service. Every day, more teams are using Access to leave their VPN behind and connect to applications quickly and securely from anywhere in the world.
We’ve heard from a number of teams about how they’re using Access. Each team has unique needs to consider as they move away from a VPN and to a zero trust model. In a zero trust framework, each request has to prove that a given application should trust its attempt to reach a secure tool. In this post, we’re highlighting some of the solutions that groups are using to transition to Cloudflare Access.
Solution 1: Collaborate with External Partners
Cloudflare Access integrates with popular identity providers (IdPs) so that your team can reach internal applications without adding more credentials. However, teams rarely work in isolation. They frequently rely on external partners who also need to reach shared tools.
How to grant and manage permissions with external partners poses a security risk. Just because you are working with a third-party doesn’t mean they should have credentials to your IdP. They typically need access to a handful of tools, not all of your internal Continue reading
