Secure Development Lifecycle for AI Systems

The adoption of artificial intelligence (AI) across various industries has been rapidly accelerating. But as AI-powered systems take on more critical business functions, security needs to be at the forefront when developing and deploying these systems. Neglecting security practices in the AI development lifecycle can result in vulnerabilities that leave AI applications open to attacks or failures in high-risk scenarios.

Threat Modeling in Design
AI developers need to think like attackers and proactively identify potential security threats and vulnerabilities in the architecture and design of AI systems. Threat modeling through techniques like STRIDE analysis can reveal risks that must be addressed early on. Subject matter experts should be included to map out “kill chains” based on possible adversary goals and capabilities.

Secure Coding Standards
Code quality is critical for all software, but even more so for AI where behavior depends heavily on code logic. Secure coding standards should be established, and peer code reviews conducted to find any security issues like injection vulnerabilities, improper error handling, or overflow errors. Unit testing each module or function is also key.

Data Security and Privacy Protections
The data used to train, validate and operate AI systems must be properly managed according to data classification policies. Any sensitive datasets should utilize encryption and access controls to prevent unauthorized access or leaks. Data minimization, de-identification and differential privacy techniques can help mitigate privacy risks.

Red Teaming and Penetration Testing
Conducting adversarial simulations allows teams to understand how threat actors may attempt to attack or manipulate the AI system, and strengthen defenses accordingly. Ethical red teaming and penetration testing exercises against AI training pipelines, model APIs, and components should occur periodically to find vulnerabilities and blind spots.

Monitoring for Drift and Errors
Continuously monitoring performance metrics, explainability dashboards, logs and other telemetry data from AI systems deployed in production can help identify gaps or unexpected changes in behavior that constitute security risks, such as data drift or adversarial inputs. The system can then be taken offline or flagged for human review.

The responsible development and deployment of AI requires putting security front and center across the entire pipeline. Organizations that integrate checks, testing and controls at multiple points in the AI development lifecycle will be better positioned to prevent, detect and respond to threats against AI systems before they result in failures or data compromise.
