Piqued the interest of the MSRC due to the reasons above, other teams at Microsoft Furthermore, the memory-unsafe operations must be explicitly marked as such, dramatically reducing the surface area security professionals must scrutinize for memory safety vulnerabilities.

Rust gives the programmer the tools to wrap these operations in safe abstractions, meaning that what was once relegated to code comments or convention can be statically enforced by the Rust compiler. In systems programming, sometimes the programmer must perform operations that cannot be statically verified as safe. We’re not the only company to have reported such findings. Rust, 70% of these security issues would most likely have been eliminated.

This means that if that software had been written in Seen, roughly 70% of the security issues that the MSRC assigns a CVE to are In a future post, we’ll revisit thoseĮxamples to see how Rust prevents those issues usually without adding any That the issues we illustrated in the previous Through usage of the “unsafe” keyword, Rust is completely memory safe, meaning Safetyįrom C and C++ is its strong safety guarantees. Performance in terms of raw speed, control, and predictability, is that Rust, C,Īnd C++ can be thought of in similar terms. Rust, just like C and C++, also gives the programmer fine-grained control on when and how much memory is allocated allowing the programmer to have a very good idea of exactly how the program will perform every time it is run.

Rust’s standard library depends on libc for platforms that support it just like C and C++, but the standard library is also optional so running on platforms without an operating system is also possible. Rust, just like C and C++ has a minimal and optional “runtime”. When thinking about why Rust is a good alternative, it’s good to think about what we can’t afford to give up by switching from C or C++ - namely performance and control. Languages which achieve memory safety through garbage collection are not ideal choices for systems programming because their runtimes can lead to unpredictable performance and unnecessary overhead. Such workloads need the speed and predictable performance that C, C++, and Rust provide. We, however, are talking about the need for a safe systems programming language (i.e., a language that can build systems other software runs on, like OS kernels). We encourage anyone who is currently using C or C++ to consider whether one of these languages would be appropriate to use instead. NET languages like C# or F# and other languages like Swift, Go, and Python.

Now we’ll peek at why we think that Rust represents the best alternative to C and C++ currently available.įirst, there are plenty of fantastic memory safe languages already available and widely used inside and outside of Microsoft, including. In this series, we have explored the need for proactive measures to eliminate a class of vulnerabilities and walked through some examples of memory safety issues we’ve found in Microsoft code that could have been avoided with a different language.
