Is Your Roadmap Prioritizing Memory Safe Programming Languages?

In an era where cybersecurity threats evolve daily, the collective stance of cybersecurity agencies from leading nations, including the USA, UK, Canada, Australia, and New Zealand, on the adoption of memory safe programming languages warrants close attention. In December of last year, these agencies outlined their position in a pivotal document titled “The Case for Memory Safe Roadmaps.” While this may venture slightly beyond our typical discussions at GitGuardian, the significance of memory safety in programming cannot be overstated in the realm of security.

Understanding Memory Safety

Before diving deeper, let’s demystify what memory safe and memory unsafe programming languages entail. Languages deemed memory unsafe, such as C++, require developers to manually manage memory allocation and deallocation. This opens the door to various issues, including memory leaks, dangling pointers, and a vulnerability to buffer overflows due to the absence of automated bounds checks.

Conversely, memory safe languages, encompassing popular choices like Python, Java, C#, Go, Rust, and Swift, aim to mitigate these risks. JavaScript’s memory safety status, particularly interesting, varies based on the runtime engine and environment. Despite this, in areas like web development, issues like memory leaks can still arise through improper DOM object management.

The Case for Memory Safety

The drive towards memory safe languages isn’t for trivial reasons. An alarming two-thirds of vulnerabilities in memory unsafe languages stem from memory management issues. This is echoed by the USA’s Cybersecurity and Infrastructure Security Agency (CISA), which advocates for a shift towards memory safe alternatives.

The real-world implications are stark. Microsoft reports that approximately 70% of their Common Vulnerabilities and Exposures (CVEs) are memory related. This pattern is seen across the tech industry, with Google’s Chromium project and Mozilla’s Firefox browser acknowledging the significant role memory issues play in their security vulnerabilities.

In an exciting development for proponents of memory safety, the Linux Kernel began officially supporting Rust-written kernel modules in 2022. Given Linux’s ubiquity in devices ranging from smartphones to smart TVs, this move signifies a major shift towards embracing memory safety at the core of technology infrastructure.

Performance concerns often arise when debating the merits of Rust and Go versus C++. However, these newer languages have been engineered to compete closely with C++ speeds. While benchmarks may vary, the performance gap is narrowing, challenging the notion that C++ is indispensable for high-performance applications.

Notably, HuggingFace’s AI library, which integrates with both Python and JavaScript, is penned in Rust. This underscores Rust’s capability to handle demanding tasks while facilitating easier programming through languages like Python.

Considering the Shift to Memory Safety

Transitioning to a memory safe language is a multifaceted decision for any organization. Factors ranging from performance needs to the specifics of your application’s domain must be weighed carefully. Nonetheless, one consolation for users of GitGuardian is that our tool’s adaptability spans nearly every programming language, ensuring your shift towards memory safety doesn’t leave you without vital security support.

Embracing memory safe languages may not eliminate every coding error, but it significantly reduces the risk of memory-related vulnerabilities. This shift allows developers to focus more on refining their code’s security posture, a critical advantage in today’s threat landscape.

Memory safety in programming is more than just a best practice; it’s a strategic security posture that can define the resilience of your applications. As the conversation around memory safe languages continues, reviewing your roadmap to prioritize these technologies could be the game-changer your security strategy needs.

This discussion extends an invitation to developers and organizations alike to reassess their technological foundations in light of emerging cybersecurity trends. By prioritizing memory safety, they’re not merely adapting to a recommendation—they’re taking a proactive step towards fortifying their code against the myriad challenges posed by modern cybersecurity threats.
