ACSC Technical Guidance
The Australian Cyber Security Centre (ACSC), part of the Australian Signals Directorate (ASD), provides the primary technical guidance for AI security in Australia. Much of this guidance is developed collaboratively with Five Eyes partners.
Core Documents
Engaging with Artificial Intelligence (2024, updated 2025)
Purpose: Introductory guidance for organisations beginning to use AI systems.
Key Security Topics:
- Data Poisoning: Manipulation of training data to cause model misbehaviour
- Prompt Injection: Adversarial inputs designed to override system instructions
- Supply Chain Risks: Third-party models, libraries, and data sources
- Model Stealing: Extraction of proprietary model weights or behaviour
- Information Disclosure: Unintended exposure of training data or sensitive information
Partners: CISA, FBI, NSA, NCSC-UK, CCCS, NCSC-NZ, Japan NISC
Implementation Notes:
- Start here for organisations new to AI security
- Cross-reference with OWASP Top 10 for LLM Applications
- Consider as baseline awareness for all staff using AI tools
Deploying AI Systems Securely (April 2024)

AI/ML Supply Chain Risks and Mitigations (October 2025)
Purpose: Managing risks from third-party AI components.
This is Australia's first standalone AI supply chain guidance.
Risk Categories:
| Risk | Description | Mitigations |
|---|---|---|
| Pre-trained Models | Backdoors, biases, malicious behaviour | Provenance verification, testing, trusted sources |
| Third-party Libraries | Vulnerabilities, supply chain attacks | Dependency scanning, version pinning, SBOM |

| Cloud AI Services | Provider security, data handling | Due diligence, contracts, monitoring |
AI Bill of Materials (AI-BOM) Components:
- Model architecture and version
- Training data sources and lineage
- Dependencies and versions
- Known limitations and failure modes
- Security testing results
Frontier Models and Their Impact on Cyber Security (April 2026)
Purpose: Guidance on preparing for the cyber security implications of frontier AI models with enhanced vulnerability discovery capabilities.
Context: Published in response to rapid advances in frontier AI model capabilities for vulnerability discovery. The ACSC guidance notes that frontier models have discovered long-standing vulnerabilities that survived decades of human review, and references industry blog posts including from Anthropic (7 April 2026) and warnings from OpenAI (December 2025) about frontier model cyber security risks.
Author's note: Anthropic's Claude Mythos model and Project Glasswing are illustrative examples of the capabilities the ACSC guidance addresses. The ACSC publication references these developments without naming specific models or products.
Key Mitigation Strategies:
| Strategy | Description | ASD References |
|---|---|---|
| Reduce attack surfaces | Assess external connectivity, apply network segmentation, limit to reputable suppliers | ISM System Hardening, Network Segmentation guidance |
| Patch every day | Adopt increased patching tempo; apply all patches regardless of severity rating | ISM System Management, Essential Eight |
| Use AI to find vulnerabilities | Leverage frontier models for Secure by Design; strengthen code before deployment | Safe Software Deployment guidance |
| Implement layered security | Defence-in-depth aligned with modern defensible architectures; zero trust principles | Secure by Design guidance |
Key Insight: AI is not creating new vulnerabilities — it is identifying those that already exist. Organisations should harness AI's vulnerability discovery capabilities defensively while preparing for adversaries using the same capabilities offensively.
Partners: References NCSC-UK analysis on defensive use of frontier models.

Information Security Manual (ISM)
The ISM is the Australian Government's cybersecurity framework. It became mandatory for non-corporate Commonwealth entities and is referenced by most state frameworks.
AI-Specific Controls
Three AI-specific controls have been added since June 2024:
ISM-1923: OWASP Top 10 for LLM
Control Text:
Risks identified in the OWASP Top 10 for Large Language Model Applications are mitigated.
OWASP Top 10 for LLM Applications (2025 v2.0):
- Prompt Injection
- Sensitive Information Disclosure
- Supply Chain Vulnerabilities
- Data and Model Poisoning
- Improper Output Handling
- Excessive Agency
- System Prompt Leakage
- Vector and Embedding Weaknesses
- Misinformation
- Unbounded Consumption
Implementation:
- Map each OWASP risk to your LLM deployment
- Implement mitigations documented in OWASP guidance
- Document residual risks and acceptance decisions
- Regular review as OWASP updates the list
ISM-1924: Adversarial Input Detection
Control Text:
Adversarial inputs, including prompt injection attempts, are detected and mitigated.
Implementation Approaches:
| Approach | Description | Effectiveness |
|---|---|---|
| Input Validation | Pattern matching, blocklists | Basic |
| Semantic Analysis | Detect instruction-like patterns | Medium |
| Anomaly Detection | ML-based input classification | High |
| Layered Prompts | System prompts resistant to injection | Medium |
| Output Filtering | Detect when injection succeeded | Complementary |
Note: Effectiveness ratings are the author's assessment based on practitioner experience, not ASD's official position. No single approach is comprehensive; defence in depth is required.
Critical: Indirect Prompt Injection
ISM-1924's scope includes adversarial inputs that may not come directly from the user. In retrieval-augmented generation (RAG) systems and agentic AI deployments, adversarial content can be injected via:
- Poisoned documents ingested by the retrieval pipeline
- Malicious content in emails, databases, or external data sources
- Compromised tool outputs in multi-step agent workflows
Organisations should implement defences against indirect injection including retrieval sandboxing, output monitoring for tool-calling systems, and canary document detection.
Practical Considerations:
- No single approach is comprehensive
- Defence in depth required
- Monitor for emerging injection techniques
- Balance security with usability
ISM-2072: AI Model Storage Formats
Control Text:
AI models are stored in formats that do not allow arbitrary code execution.
Background: Pickle files (common in Python ML) can execute arbitrary code on load, enabling supply chain attacks.
Safe Formats:
- safetensors - Recommended; no code execution possible
- ONNX - Open format; safe when custom operators are disabled or restricted to a known allowlist
- TensorFlow SavedModel - When restricted to frozen graphs; disable py_function and custom layer code execution
- GGUF/GGML - Quantized format; inherently safe
Unsafe Formats:
- pickle (.pkl, .pt, .pth) - Arbitrary code execution
- joblib - Python serialisation; code execution possible
- Custom formats - Assess case by case
- PyTorch .bin - Uses pickle serialisation internally despite different extension
- Keras HDF5 (.h5) - Lambda layers can contain arbitrary Python code
Implementation:
- Convert existing models to safetensors where possible
- Scan incoming models for pickle content
- Establish approved formats list for procurement
- Training for ML engineers on secure formats
