Which threats affect an AI system that did not exist before?
The catalogue holds 52, 45 of them in operation. What is new against classic application security are mainly five groups: prompt attacks and guardrail bypass, manipulation of model and training data, autonomous agents, data leakage through the model, and harmful content from generation.
What is indirect prompt injection and what helps against it?
Instructions do not come from the user but from a source the system processes: a document, a web page, an image description, a tool response. The model follows them because it does not separate instruction from content. The entry in the threat catalogue lists the mitigations against this, each with its reference in the framework.
How do I secure a system that acts on its own?
Before the first real permission come five decisions: scope of rights, level of autonomy, approval requirements, logging and a kill switch. The catalogue holds five threats on autonomous agents, among them persistently poisoned memory and insecure communication between agents.
Which frameworks does the catalogue cover?
Seven, with 486 documented mappings from 21 primary sources: the EU AI Act with 51 threats, the risk framework of the US standards institute with 47, the OWASP Foundation priority list with 45, MITRE ATLAS with 44, plus the GDPR, the publications of the German federal office and the architectural analyses of the Berryville Institute. Every framework page also states which threats it does not reach.
Which threats are actually relevant for my system?
That depends on the system type and its architectural properties. The application-context analysis lets you select both and then shows which of the 52 threats always apply and which only in specific cases. A system without tool access does not need the agent group; a system without its own training needs the poisoning group only conditionally.
How do the mitigations work and where do they take effect?
265 mitigations each carry their control type, their effect and their implementation level. The effect matrix sets both against each other: which control type works on which topic group and where gaps remain. The attack path shows, for every threat, the five points where a mitigation can take effect.
Which EU AI Act obligation directly concerns security?
Art. 15 requires high-risk systems to achieve an appropriate level of accuracy, robustness and cybersecurity across the whole life cycle, expressly including resilience against attacks. For deployers Art. 26(5) is added: monitor operation and suspend it when a risk emerges.
What does the application explicitly not do for security?
It examines no running system, it reads no logs and it detects no attack. It replaces neither a management system nor a security test. It assesses a state based on what you record; whether a mitigation actually works in the specific system is not verified.
