AI Pipeline DFIR: Data Poisoning, Supply Chain & Training Integrity by Tonex
Modern AI teams need incident response that reaches beyond endpoints into data pipelines, base models, and fine-tuning flows. This course builds a digital forensics and incident response (DFIR) playbook for the AI lifecycle—collecting evidence, validating provenance, and proving or disproving training-time tampering. Impact on cybersecurity is direct and significant: poisoned datasets and backdoored models translate into exploitable behaviors at deployment. Strengthening AI pipeline integrity reduces attack surface across MLOps, CI/CD, and vendor ecosystems. By the end, participants can trace compromises from artifact to outcome and demonstrate whether corrupted data influenced model behavior.
Learning Objectives:
- Construct repeatable DFIR processes for AI training and fine-tuning pipelines
- Identify and triage poisoning, backdoors, and supply-chain manipulations in models and datasets
- Collect, preserve, and analyze AI-specific forensic artifacts with defensible chain of custody
- Map indicators of compromise to data lineage, model versions, and training runs
- Communicate risk and remediation to engineering and leadership with evidence-backed findings
- Strengthen cybersecurity by hardening AI data flows, dependencies, and release gates
Audience:
- Cybersecurity Professionals
- Incident Responders and Threat Hunters
- ML/AI Engineers and MLOps Practitioners
- Security Architects and GRC Analysts
- Product Security and Red Teams
- Technical Program/Project Managers in AI
