As artificial intelligence (AI) becomes more embedded in business operations, the security of the data that powers these systems is becoming a critical concern. A new joint publication from the Australian Cyber Security Centre (ACSC), in collaboration with global partners, outlines how organisations can protect their AI systems from data-related threats—and why it matters more than ever.

Why This Matters

AI systems are only as good as the data they’re trained on. If that data is compromised—whether through tampering, poor sourcing, or gradual degradation—your AI’s decisions can become inaccurate, biassed, or even dangerous. This isn’t just a technical issue; it’s a business risk.

Key Takeaways from the Australian Cyber Security Centre’s AI Data Security Guidance

Secure the Entire AI Lifecycle

From development to deployment, every stage of your AI system must be protected. This includes:

1. Data collection
2. Model training
3. Ongoing operation and updates

Three Major Risk Areas to Watch

The report highlights three critical threats:

Data Supply Chain Risks

Poorly sourced or unverified data can introduce vulnerabilities. Always vet your data sources and maintain a clear chain of custody.

Maliciously Modified (“Poisoned”) Data

Attackers may subtly alter training data to manipulate AI outcomes. Use techniques like digital signatures and anomaly detection to guard against this.

Data Drift

Over time, real-world data can change, making your AI less accurate. Regularly retrain and validate your models to stay aligned with current conditions.

AI Best Practices You Can Implement Today

1. Encrypt sensitive data at rest and in transit.
2. Use digital signatures to verify data integrity.
3. Track data provenance to understand where your data comes from.
4. Store data securely using trusted infrastructure.
5. Regularly audit and test your AI systems for vulnerabilities.
