Deep dives
The Role of Rust in Android's Security Improvements
Rust is increasingly adopted within Android for improving security, particularly due to its potential to eliminate memory safety vulnerabilities. The Android security team recognized that most security defects occur in new code, prompting the initiative to replace some legacy C++ components with Rust. This strategic shift not only enhances the security posture by mitigating common vulnerabilities but also aims to remove the overhead caused by isolating untrusted libraries in separate processes. By integrating Rust, Android seeks to maintain performance while ensuring that new code is more resilient against attacks.
