Episode 4 — Data Lifecycle Security

This episode examines data lifecycle security, covering the journey of data from collection and labeling through storage, retention, deletion, and provenance management. It explains why data is the foundation of AI system reliability and how its misuse or compromise undermines security objectives. For certification preparation, learners are introduced to key definitions of provenance, integrity, and retention policies, while understanding how regulatory requirements drive data governance practices. The episode situates data lifecycle security as both a technical and compliance necessity, bridging privacy, accuracy, and accountability in AI environments.The applied discussion focuses on real-world considerations such as how unvetted datasets can introduce bias or poisoning, how insecure storage creates risks of leakage, and how failure to enforce deletion or retention policies leads to regulatory violations. Best practices include documenting data sources, applying encryption at rest and in transit, and ensuring role-based access controls for labeling and preprocessing steps. Troubleshooting scenarios emphasize what happens when provenance cannot be established or when training datasets contain sensitive information without consent. For exams and professional practice, this perspective reinforces why lifecycle controls must be embedded in organizational AI policies, not treated as optional afterthoughts.
