Purdue Model OT Cybersecurity Auditor using Pydantic AI

Modern industrial architectures mix cloud analytics directly with operational networks, breaking traditional Purdue Model segmentation. Develop a type-safe cybersecurity compliance auditor using Pydantic AI and Taskade to validate IEC 62443 zone and conduit isolation standards across industrial network topology graphs.

Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Create a type-safe Pydantic AI agent workflow to audit Purdue Model zone transitions and detect unauthorized Level 0 to Level 4 cross-boundary traffic.

Delivery guide

How work is evaluated

Evaluation

Validates that the Pydantic AI agent accurately identifies forbidden cross-zone traffic channels in complex OT network schemas.

Datasets

Shared data for this challenge

Review public datasets and any private uploads tied to your build.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

violation_detection_accuracy

Verifies all Level 0/1 to Level 4 direct connections are flagged.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

schema_conformance_rate

Percentage of generated responses matching Pydantic validation schema without errors. • target: 1 • range: 0.9-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Define Pydantic schema constraints for Purdue Model Levels 0 through 5

  • Integrate Pydantic AI agents with Taskade structured execution tasks

  • Scan OT network routing tables and firewall configs for unauthorized conduits

  • Generate structured ISA/IEC 62443 compliance audit reports

Resources and assets

Reference links and supporting material

Dataset notes

Synthetic OT network topology definitions, router ACL tables, and Purdue Model zone assignment specifications.

How this agent runs

Validates that the Pydantic AI agent accurately identifies forbidden cross-zone traffic channels in complex OT network schemas.

Challenge input
