AI-Written Code: Security Risks Businesses Can't Ignore

The world of software development is rapidly evolving, and businesses are taking notice. One of the BIGGEST headlines of 2024 is the emergence of AI software engineers like Devin, developed by Cognition Labs. Imagine an AI assistant that can not only write boilerplate code and automate repetitive tasks, but build entire applications by itself! Devin's capabilities, including successfully completing real freelance jobs and resolving complex coding issues, have sent shockwaves through the tech industry. Experts are calling it a game-changer, but alongside the benefits come potential security risks that businesses can't ignore.

This post explores some of the common vulnerabilities that AI-written code can introduce and explores how we can mitigate them.

Vulnerability Sources in AI-Generated Code

• Hidden Biases: Let's say your company is developing a new e-commerce platform. You train your AI on existing code from various online stores. Unfortunately, some of those stores might have weak password hashing practices. The AI, unaware of the security risk, might generate code for your platform with the same flawed hashing algorithm. This could leave your customer data vulnerable to hacking.
• Incomplete Specifications: Imagine you're building a mobile app with a login feature. You instruct your AI to "create a user authentication system." While the AI might generate the core functionality, it might miss crucial security elements like two-factor authentication if it wasn't explicitly specified in the instructions. This could leave your app users susceptible to account takeovers.
• Lack of Security Expertise: While AI can automate some coding tasks, it can't replace the need for human security expertise. Imagine a scenario where your AI generates code for a new financial services application. The code might function as intended, but without a developer with security knowledge reviewing it, vulnerabilities like buffer overflows or SQL injection points might remain undetected.

Securing the Future: How to Mitigate Risks

• Security-Focused Training Data: Think of training data as the building blocks for your AI. Just like using high-quality materials to build a house, training your AI on codebases with strong security practices can help reduce the likelihood of vulnerabilities in the generated code.
• Clear and Precise Specifications: Providing clear and detailed instructions is essential. For example, when instructing your AI to create a login system, be specific about password complexity requirements and the need for two-factor authentication.
• Human-in-the-Loop Approach: Don't rely solely on AI for secure code. Developers must review AI-generated code to identify and fix vulnerabilities before deployment. Think of it as a team effort where AI handles the heavy lifting, and human expertise ensures security.
• Static Application Security Testing (SAST) Tools: These automated tools can analyze AI-generated code for common security vulnerabilities. This adds another layer of defense by identifying potential issues before they become real problems.

By acknowledging these potential vulnerabilities and implementing proper safeguards, businesses can leverage the power of code-generative AI while maintaining a strong security posture.
