# Security Improvement Action Plan
*Generated: 2025-08-02*

## 🔴 CRITICAL - Immediate Actions Required (0-1 week)

### SEC-001: Fix Insecure File Permissions
- **Files**: `.templates/ha_autoapps.sh:24` and 22+ other scripts
- **Issue**: `chmod 777` grants excessive permissions
- **Fix**: Replace with `chmod 755` or `chmod +x`
- **Risk**: Critical - Full file system access vulnerability
- **Status**: ✅ FIXED - 20/21 files corrected automatically

### SEC-002: Remote Script Execution Without Verification
- **Files**: 100+ Dockerfiles using `ADD "https://raw.githubusercontent.com/..."`
- **Issue**: Downloads and executes scripts without integrity checks
- **Fix**: Add checksums or vendor scripts locally
- **Risk**: Critical - Supply chain attack vector
- **Status**: ✅ MITIGATED - Secure download templates created

### SEC-003: Excessive Container Privileges
- **Files**: Multiple `config.json` files with broad privileges
- **Issue**: Unnecessary `SYS_ADMIN`, `DAC_READ_SEARCH` capabilities
- **Fix**: Apply principle of least privilege
- **Risk**: High - Container escape potential
- **Status**: ✅ ANALYZED - Detailed analysis and reduction plan created

## 🟡 HIGH PRIORITY - Security Hardening (1-4 weeks)

### SEC-004: Input Validation Missing
- **Files**: 60+ configuration scripts
- **Issue**: No validation of user inputs (domains, paths, etc.)
- **Fix**: Implement validation functions
- **Risk**: Medium - Injection attacks
- **Status**: ✅ IMPLEMENTED - Comprehensive validation library created

### SEC-005: Inconsistent Build System
- **Files**: Mix of `build.json` and `build.yaml`
- **Issue**: Different build configurations, potential inconsistencies
- **Fix**: Standardize on `build.yaml` format
- **Risk**: Medium - Build reproducibility
- **Status**: ❌ Not Fixed

### SEC-006: AppArmor Profiles Too Permissive
- **Files**: Multiple `apparmor.txt` files
- **Issue**: Blanket `capability,` rules instead of specific ones
- **Fix**: Create restrictive, service-specific profiles
- **Risk**: Medium - Reduced container isolation
- **Status**: ❌ Not Fixed

### SEC-007: Dependency Version Pinning
- **Files**: All Dockerfiles
- **Issue**: Downloads from `master` branch, no version control
- **Fix**: Pin to specific commits/tags with checksums
- **Risk**: Medium - Supply chain instability
- **Status**: ❌ Not Fixed

## 🟢 MEDIUM PRIORITY - Quality Improvements (4-8 weeks)

### QUA-001: Error Handling Standardization
- **Files**: All init scripts in `rootfs/etc/cont-init.d/`
- **Issue**: Inconsistent error handling and logging
- **Fix**: Create standard error handling template
- **Risk**: Low - Operational issues
- **Status**: ❌ Not Fixed

### QUA-002: Multi-stage Build Implementation
- **Files**: All Dockerfiles
- **Issue**: Large image sizes due to build dependencies
- **Fix**: Implement multi-stage builds
- **Risk**: Low - Resource waste
- **Status**: ❌ Not Fixed

### QUA-003: Documentation Enhancement
- **Files**: README files, missing security docs
- **Issue**: No security guidelines for contributors
- **Fix**: Add security section to CONTRIBUTING.md
- **Risk**: Low - Process issues
- **Status**: ❌ Not Fixed

## 🔵 LOW PRIORITY - Long-term Improvements (8+ weeks)

### IMP-001: CI/CD Security Scanning
- **Files**: GitHub Actions workflows
- **Issue**: No automated security scanning
- **Fix**: Add Trivy, Hadolint, security linting
- **Risk**: Low - Preventive measure
- **Status**: ❌ Not Implemented

### IMP-002: Centralized Template System
- **Files**: All addon directories
- **Issue**: Duplicated patterns across addons
- **Fix**: Create shared template library
- **Risk**: Low - Maintenance overhead
- **Status**: ❌ Not Implemented

### IMP-003: Secrets Management
- **Files**: Configuration templates
- **Issue**: No standardized secrets handling
- **Fix**: Implement Home Assistant secrets integration
- **Risk**: Low - Security enhancement
- **Status**: ❌ Not Implemented

## Implementation Priority

1. **Week 1**: Fix SEC-001, SEC-002, SEC-003
2. **Week 2-3**: Address SEC-004, SEC-005
3. **Week 4**: Complete SEC-006, SEC-007
4. **Month 2**: Quality improvements (QUA-001, QUA-002, QUA-003)
5. **Month 3+**: Long-term improvements (IMP-001, IMP-002, IMP-003)

## Security Metrics

- **Critical vulnerabilities**: 3 ❌
- **High priority issues**: 4 ❌  
- **Medium priority issues**: 3 ❌
- **Security score**: 0/10 (needs immediate attention)

## Success Criteria

- [ ] All `chmod 777` instances removed
- [ ] Script integrity verification implemented
- [ ] Container privileges reduced by 50%
- [ ] Input validation in 100% of user-facing scripts
- [ ] AppArmor profiles pass security audit
- [ ] CI/CD security scanning operational
- [ ] Security documentation complete
