Episode 9 — Training-Time Integrity

This episode covers training-time integrity, focusing on the assurance that data, processes, and infrastructure used in model development remain uncompromised. Learners preparing for exams must understand that threats at this stage include data tampering, corrupted labels, or manipulated hyperparameters. Unlike inference-time attacks, which target deployed models, training-time compromises affect the foundation of the model itself, potentially embedding vulnerabilities that persist throughout the lifecycle. The exam relevance lies in being able to identify how training-time risks manifest and what practices are used to safeguard against them.Examples of threats include adversaries with insider access altering training pipelines, attackers injecting mislabeled data into supervised learning sets, or subtle manipulations of evaluation metrics to distort reported accuracy. Best practices include reproducibility through version control, audit logs of dataset provenance, and multi-party review of training processes. Troubleshooting considerations emphasize detecting when anomalous behavior is due to data corruption rather than algorithmic flaws, a distinction often tested in certification contexts. For practitioners, ensuring training-time integrity is critical because any compromise at this stage undermines all subsequent defenses.
