Pretrained Models Security
Manage and secure pretrained AI models from external sources with verification, scanning, and safe deployment practices.
Why Pretrained Model Security Matters
Pretrained models from external sources carry risks:
- Unknown provenance - Origin may be uncertain
- Hidden backdoors - Malicious triggers embedded
- Vulnerabilities - Known security issues
- License compliance - Legal requirements
- Data leakage - Sensitive training data exposure
Pretrained Model Features
Model Registry
Central repository for pretrained models:
- Model metadata storage
- Version management
- Access control
- Usage tracking
- Security status
Provenance Verification
Verify model origins:
- Source validation
- Creator verification
- Chain of custody
- Cryptographic signatures
- Authenticity checks
Security Scanning
Comprehensive model analysis:
- Malware detection
- Backdoor scanning
- Vulnerability assessment
- Weight analysis
- Serialization security
License Management
Track model licenses:
- License type identification
- Compliance requirements
- Usage restrictions
- Attribution needs
- Commercial use rights
Using Pretrained Models
Adding a Model
- Navigate to AI Security → Pretrained Models
- Click Add Model
- Provide model information:
- Name and version
- Source location
- Model type
- Intended use
- Upload or link model
- Initiate security scan
Security Assessment
Each model undergoes:
- Provenance check - Verify source authenticity
- Integrity scan - Check for tampering
- Malware scan - Detect malicious code
- Vulnerability scan - Find known issues
- License analysis - Verify compliance
Assessment Results
Results include:
- Security Score - Overall safety rating
- Findings - Detailed issues found
- Recommendations - Actions to take
- Approval Status - Safe to use or not
Approving Models
Models can be:
- Approved - Safe for production use
- Conditional - Approved with restrictions
- Pending - Awaiting review
- Rejected - Not safe to use
Model Lifecycle
Onboarding
- Submit model for review
- Automatic scanning
- Human review (if needed)
- Approval decision
- Registration in catalog
Maintenance
- Regular re-scanning
- Vulnerability updates
- Version management
- Usage monitoring
- Compliance tracking
Retirement
- Deprecation notice
- Usage migration
- Access revocation
- Archive or deletion
- Documentation update
Safe Deployment
Pre-deployment Checklist
- Model approved in registry
- Latest security scan passed
- License compliance verified
- Access controls configured
- Monitoring enabled
Deployment Controls
- Approved models only
- Version pinning
- Rollback capability
- Access logging
- Performance monitoring
Post-deployment

Model Categories
By Source
- Open Source - Community models
- Commercial - Vendor-provided
- Internal - Organization-trained
- Research - Academic sources
By Risk Level
- Low Risk - Well-established, widely used
- Medium Risk - Newer or less verified
- High Risk - Unknown source or issues found
- Critical Risk - Known vulnerabilities
Best Practices
- Never use unscanned models - Always verify before use
- Maintain a central registry - Track all models
- Regular re-assessment - Security status changes
- Document everything - Source, purpose, approvals
- Monitor model behavior - Detect anomalies in production
