Week 18: Targeted Remediation of Weakest Controls & Clean-Room Final Acceptance Runs (Projects 1 & 2)

The five hours

  1. 01

    Concepts & system design

    60 min

    R19 — HF Datasets

    R20 — Model Cards

    R45 — NIST AI 100-2 poisoning limits

    Read the assigned sections; map the mechanism, threat model and trade-offs.

  2. 02

    Project implementation

    120 min

    Revisit your training-data poisoning experiment (M2) and RAG/vector poisoning controls (D5, D10). Tighten outlier/provenance checks and trigger-detection heuristics.

    Build, integrate, debug and improve the increment in the active project.

  3. 03

    Security lab

    60 min

    Test a subtler poisoning/trigger variant; record exact detection sensitivity, false-positive rates, and the mathematical/practical limits of anomaly detection and retraining.

    Test the abuse case, failure path, authorization bypass or resource limit.

  4. 04

    Verification & evidence

    30 min

    Updated poisoning evaluation report and hardened D5/D10 tests.

    Add or run regression tests; record the 9-point evidence record.

  5. 05

    Deliberate practice & Socratic review

    30 min

    Answer the 8 Socratic questions without notes: What? Why? How? What if? Why not? How can I prove it? Where can it break? What have I learned?

    Re-explain the hardest concept aloud, inspect one edge case, update the gap log.

    Adversarial Machine Learning: A Taxonomy and Terminology of Attacks and Mitigations (NIST AI 100-2e2023)

    The evasion/poisoning/privacy/abuse taxonomy with predictive-integrity and availability framing used as the day's classification scheme.

    Anthropic - AI sleeper agents?

    A paper walkthrough of backdoored models that persist through SFT, RL, and adversarial training, including why adversarial training can teach a model to hide its trigger — directly relevant to why behavioural filters alone fail.

    Data Poisoning and Adversarial AI with Dr. Arash Rahnama

    Covers where poisoning enters the pipeline, defensive controls, robustness, and detection tooling in sequence, ending on practical advice for building detection into the data path.

    Backdoors in LLMs: Why model scanning isn't enough

    Explains why a clean scan says nothing about weights that were never malicious code, then covers activation probes as a runtime backdoor signal with their generalisation caveats.

    Model Cards for Model Reporting

    The original model-card structure — intended use, limitations, training data, and disaggregated evaluation — which is the provenance record you cite when a poisoned or mis-scoped dataset is the root cause.
