This post illustrates some of the Linux Kernel features, which are helping us to keep our production systems more secure. We will deep dive into how they work and why you may consider enabling them as well
Many leaks happen because of software bugs and security vulnerabilities. In this post we will learn how the Linux kernel can help protect cryptographic keys from a whole class of potential security vulnerabilities: memory access violations.
Continue learning how to import and execute code from an object file. In this part we will handle external library dependencies.
Continue learning how to import and execute code from an object file. This time we will investigate ELF relocations.
Ever wondered if it is possible to execute an object file without linking? Or use any object file as a library? Follow along to learn how to decompose an object file and import code from it along the way.
In this post we will review Linux seccomp and learn how to sandbox any (even a proprietary) application without writing a single line of code.
Encrypting data at rest is vital for Cloudflare with more than 200 data centres across the world. In this post, we will investigate the performance of disk encryption on Linux and explain how we made it at least two times faster for ourselves and our customers!
At Cloudflare we like Go. We use it in many in-house software projects as well as parts of bigger pipeline systems. But can we take Go to the next level and use it as a scripting language for our favourite operating system, Linux?
