LiveOverflow. Frames prompt injection as a classic injection attack against systems that mix instructions and untrusted data — with a concrete content-moderation example where an attacker frames an innocent user. The mental shift from "the model is the target" to "the application is the target" is exactly the move the article opens with.
Treat this as conceptual guidance. Do not use real company data until permissions, retention, logging and human-review boundaries are clear.
Model prompt injection as untrusted-data mixing and design boundaries around tool use.
General web-security intuition helps; no prior LLM-security knowledge assumed.

AWS Skill BuilderAWS Training and Certification
A cloud-vendor-specific complement to the Macquarie specialization: AWS's own Generative AI Security Scoping Matrix, OWASP Top 10 for LLMs, and MITRE ATLAS, walked through governance, legal, and compliance controls for five different AI deployment scopes — from consumer apps to self-trained models. Not GDPR-specific, but a genuinely practical advanced pick for teams whose AI workloads actually run on AWS and need concrete data-governance and compliance controls, not just theory.

The advanced, most explicitly on-target answer to our GDPR × AI gap: a three-course specialization from Macquarie University's Cyber Security Hub that goes from GDPR/CCPA fundamentals and privacy-by-design, through privacy impact assessments, to a dedicated third course on securing AI systems against adversarial attacks and model leakage. Genuinely bridges 'GDPR compliance' and 'AI security' rather than treating them as separate topics.

The rare AI Act course written for the companies the Act actually reaches: SMEs adopting AI, not the labs building it. Hosted on the European Commission's own skills platform, it pairs the legal side — roles, obligations, risk classification — with the security side (prompt injection, data leakage, supplier due diligence) that most compliance courses skip. For an Estonian SME deploying AI, this is the practical starting point.
