Rust-proofing the internet with ISRG's Prossimo

You know the non-profit Internet Security Research Group (ISRG) for its Let’s Encrypt certificate authority, the most popular way of securing websites with TLS certificates. The group wants to do more. Its newest project, Prossimo, seeks to make many basic internet programs and protocols memory-safe by rewriting them in Rust.

Rust, like some other memory-safe programming languages such as Go and Java, prevents programmers from introducing some kinds of memory bugs. All too often memory safety bugs go hand-in-hand with security issues. Unfortunately, much of the internet’s fundamental software is written in C, which is anything but memory safe. 

Of course, you can write memory-safe programs in C or C++, but it’s difficult. Conversely, you can create memory bugs in Rust if you try hard enough, but generally speaking Rust and Go are much safer than C and C++.

There are many kinds of memory safety bugs. One common type is out-of-bounds reads and writes. In these, if you wrote code to track a to-do list with 10 items in C without memory protection measures, users could try to read and write for an 11th item. Instead of an error message, you’d
