# 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

|
|
5. **Month 3+**: Long-term improvements (IMP-001, IMP-002, IMP-003)
|
|
|
|
