To the average person, weather forecasts inform whether or not they need to bring an umbrella to the office. But to some, it can be quite literally a matter of life and death. Organizations like the European Center for Medium Range Weather Forecasting (ECMWF) sit at the center of a web of highly sensitive operations, providing them weather predictions and reports.

This summer, Ada Logics integrated continuous fuzzing into Teleport to strengthen the security posture of the project. We’d like to thank Adam Korczynski from Ada Logics for initiating contact and doing the work. In this blog post, we will give a brief introduction to fuzzing and explain how to carry on the work moving forward. The motive for this work was to take the first steps in implementing fuzzing into Teleport’s development pipeline.

The maturation of software development has been driven by the increasing segmentation of functions into their own portable environments. Infrastructure is splintered into dozens of computing resources, physical servers, containers, databases, Kubernetes pods, dashboards, etc. Such compartmentalization has made it incredibly simple for developers to enter their desired environments with minimal disruption to other working parts.

Modern languages like Python, NodeJS, and Go make it easy to handle concurrent requests for multiple customers at the same time by using threads or goroutines. Such services seem very cost effective because one process can handle hundreds or thousands of tenants. However, this efficiency comes at a hidden, steep price. When language runtime scheduling breaks down, one tenant can cause an outage for everyone.

This blog post marks an important milestone for us! Just four years ago, as we grew frustrated with the state of SSH server access, Teleport was born. Eventually it grew way bigger than just SSH access, as our users want to use the same access workflow for all layers of their stacks. And today we’re announcing another way to use Teleport: as a hosted offering. Let’s dig deeper!
