Rust is rapidly emerging as a preferred language for safety-critical and embedded systems, thanks to its memory safety guarantees and strong type system. However, its adoption is not without challenges, especially when integrating with legacy C and C++ codebases. Many industries—such as automotive, aerospace, and cybersecurity—rely on hybrid Rust/C/C++ projects, creating potential security risks that require advanced formal verification methods.
TrustInSoft, a leader in software security and code verification, is addressing these challenges by expanding its expertise beyond C and C++ to include Rust. Through the Rust Code Analysis Services and its participation in the Safety-Critical Rust Consortium, TrustInSoft is driving Rust’s adoption in high-assurance environments.
The Importance of Memory Safety in Rust
Memory safety is a fundamental concern in software security, especially in embedded systems where reliability is crucial. Rust’s ownership model significantly reduces common memory vulnerabilities, but it still allows “unsafe“ blocks. These blocks provide developers with low-level control but also introduce risks if not handled correctly.
Additionally, Rust’s panic!( ) macro, which triggers runtime errors, can be problematic in safety-critical environments where predictable behavior is essential. Given that Rust is often used alongside C and C++, these hybrid Rust/C/C++ projects require advanced analysis to ensure memory safety and security compliance.
TrustInSoft’s Commitment to Rust Safety
TrustInSoft has a long history of securing C and C++ code through exhaustive formal verification methods. Now, the company is bringing that same rigor to Rust. As a member of the Safety-Critical Rust Consortium, TrustInSoft is actively enhancing Rust support within its TrustInSoft Analyzer.
Through the Rust Code Analysis Services, TrustInSoft offers Rust code analysis today, allowing organizations to detect and mitigate security risks in their hybrid projects. Later this year, the company will extend this support to customers using TrustInSoft Analyzer on-premise.
Hybrid Rust/C/C++ Code and the Need for Formal Verification
Many industries adopting Rust do so incrementally, meaning Rust often coexists with legacy C and C++ code. However, this hybrid approach introduces potential security risks:
- Unsafe Interoperability – Rust’s memory safety guarantees do not automatically extend to C and C++ code, which may introduce vulnerabilities.
- Undefined Behavior Risks – Improper handling of pointers, data structures, and memory allocation between Rust and C/C++ can lead to unpredictable behavior.
- Security Compliance Issues – Safety-critical industries must adhere to strict verification standards that are difficult to achieve with hybrid Rust/C++ code.
As hybrid development becomes more common, formal verification is increasingly necessary to ensure memory safety, correctness, and compliance.
Extending TrustInSoft Analyzer to Rust
Later this year, TrustInSoft will extend TrustInSoft Analyzer to support on-premise Rust analysis, providing companies with the same level of exhaustive formal verification they already rely on for C and C++. This aligns with industry recommendations, such as:
- The ONCD report urges companies to adopt formal methods to reduce memory safety vulnerabilities.
- The CISA update recommends shifting new developments to memory-safe languages like Rust.
With these initiatives, TrustInSoft is helping companies navigate the transition to Rust without compromising security.
Rust in Embedded Systems and Automotive Industry
The embedded systems industry, particularly the automotive sector, is leading the adoption of Rust due to its safety and performance benefits. However, these industries require rigorous verification to meet regulatory standards.
TrustInSoft’s technology enables:
- Detection of memory safety issues in Rust and C/C++ integration
- Exhaustive formal verification for mission-critical systems
- Compliance with industry regulations for automotive, aerospace, and cybersecurity
By offering Rust code analysis today and extending support to on-premise users in the near future, TrustInSoft provides a practical and scalable solution for organizations transitioning to Rust.
