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​
- Continuous monitoring
- Periodic re-assessment
- Incident response plan
- Update procedures
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
