3.9
Risk
Insecure Temporary Artifacts or Intermediate Data Storage
Description
Temporary files, caches, or intermediate datasets generated during model training or data processing are not securely managed, potentially exposing sensitive data or models.
Example
Preprocessed sensitive training data is left in a world-readable scratch directory after training.
Assets Affected
Dataset / RAG
Model files
Agent Memory/cache
Mitigation
- Apply strict access controls to temporary storage
- Automatically clean up sensitive artifacts after processing
- Encrypt intermediate files if they contain sensitive data
- Monitor storage locations for unauthorized access
Standards Mapping
- ISO 42001: A.7.4, A.4.5
- OWASP Top 10 for LLM: LLM02
