1. The Rising Importance of AI Security
Artificial intelligence is no longer a niche research topic; it’s embedded in critical systems—autonomous vehicles, medical diagnostics, financial trading, and national security.
1.1 Why AI Is a New Attack Surface
Unlike traditional software, AI systems learn from data and can adapt in unpredictable ways. Attackers can manipulate the training data, poison the model, or exploit inference leaks—techniques that have no analog in classical code.
1.2 The Stakes: Business, Privacy, Societal Impact
A compromised AI model can lead to costly recalls, legal liability, reputational damage, and even loss of life. In 2023, a single data breach of a health‑tech AI platform exposed 4.5 million patient records, costing the company $125 million in fines and remediation.
2. The Most Common AI Security Threats
| Threat | Typical Vector | Real‑World Example | Impact |
|---|---|---|---|
| Adversarial Attacks | Input perturbation | 2022: Autonomous car misidentified a stop sign due to pixel‑level noise | Physical harm, liability |
| Model Theft | API exploitation, reverse engineering | 2023: OpenAI model leaked via unprotected cloud storage | IP loss, competitive disadvantage |
| Data Privacy Leaks | Membership inference, model extraction | 2024: Facial recognition service leaked identities of 2 million users | GDPR fines, privacy breach |
