# Security Module

A comprehensive security governance system that provides automated tracking, documentation, and remediation planning for security vulnerabilities.

## Overview

This security module maintains real-time visibility into security posture through:
- **Live findings document** (`security/findings/SECURITY_FINDINGS.md`)
- **Structured remediation planning** (`security/findings/remediation-plans.yml`)
- **Historical tracking and audit trails** (`security/findings/history/`)
- **Automated synchronization** with security scan results

## Quick Start

### 1. Initial Setup

The directory structure is already created. To begin using the security module:

1. Configure your security scanners to output to `security/reports/latest/`
2. Run your security scans (pip-audit, bandit, etc.)
3. Execute the automation scripts to generate findings and remediation plans

### 2. Running Security Scans

```bash
# Example pip-audit scan
pip-audit --format=json --output=security/reports/latest/pip-audit.json

# Example bandit scan
bandit -r . -f json -o security/reports/latest/bandit.json

# Generate dependency tree
pip freeze > security/reports/latest/dependency-tree.txt
```

### 3. Generate Findings Document

```bash
# Run the core automation (when implemented)
python security/scripts/update-findings.py
```

This will:
- Parse scan results from `security/reports/latest/`
- Generate/update `security/findings/SECURITY_FINDINGS.md`
- Synchronize `security/findings/remediation-plans.yml`
- Update historical tracking files

## Configuration

### Scanner Settings

Edit `security/config/scanner-settings.yml` to configure:
- Which scanners are enabled
- Output file locations
- Scanner-specific options
- Archival settings

### Remediation Defaults

Edit `security/config/remediation-defaults.yml` to customize:
- Default values for new findings
- Status workflow definitions
- Priority levels and SLA targets
- Assignment rules by severity

## Workflow

### Automated Workflow

1. **Security scans run** (CI/CD or manual)
2. **Scan results** saved to `security/reports/latest/`
3. **Automation script** processes results
4. **Findings document** updated automatically
5. **Remediation plans** synchronized (1:1 with findings)
6. **Historical data** preserved for audit trails

### Manual Remediation Planning

1. Review findings in `security/findings/SECURITY_FINDINGS.md`
2. Edit remediation plans in `security/findings/remediation-plans.yml`
3. Manual edits are preserved during automatic synchronization
4. Track progress through status updates

## Key Features

### Live Findings Document

- **Always current**: Reflects latest scan results
- **Severity ordered**: Critical findings first
- **Temporal information**: Discovery dates, aging
- **Rich context**: Descriptions, impact, references
- **Remediation status**: Current plans and progress

### Remediation Registry

- **1:1 mapping**: Every finding has a remediation entry
- **Automatic sync**: New findings get default plans
- **Manual editing**: Preserve custom remediation details
- **Status tracking**: From discovery to completion
- **Audit trail**: Historical changes preserved

### Historical Tracking

- **Findings changelog**: When vulnerabilities were discovered/resolved
- **Remediation timeline**: Progress tracking over time
- **Archived scans**: Historical scan data for trend analysis
- **Compliance reporting**: Audit trails for due diligence

## Integration

### CI/CD Integration

This module integrates with existing GitHub Actions workflows:

```yaml
# Example workflow step
- name: Update Security Findings
  run: |
    # Run security scans
    pip-audit --format=json --output=security/reports/latest/pip-audit.json
    bandit -r . -f json -o security/reports/latest/bandit.json
    
    # Update findings document
    python security/scripts/update-findings.py
    
    # Commit changes if any
    git add security/
    git commit -m "chore: update security findings" || exit 0
```

### Modular Deployment

This security module is designed to be:
- **Self-contained**: All dependencies within `security/` directory
- **Reusable**: Copy to any project with minimal configuration
- **Consistent**: Same behavior across different project structures
- **Minimal setup**: Works with standard security scanning tools

## Compliance and Reporting

The module supports compliance requirements through:
- **Audit trails**: Complete history of findings and remediation
- **Response time tracking**: Metrics on discovery-to-resolution
- **Documentation**: Clear evidence of security governance
- **Standardized process**: Consistent approach across projects

## Troubleshooting

### Common Issues

1. **Missing scan files**: Ensure scanners output to `security/reports/latest/`
2. **Permission errors**: Check write permissions on `security/` directory
3. **Malformed scan output**: Verify scanner configuration and output format
4. **Sync conflicts**: Manual edits in remediation plans are preserved

### Getting Help

1. Check scanner configurations in `security/config/scanner-settings.yml`
2. Review default values in `security/config/remediation-defaults.yml`
3. Examine automation script logs for error details
4. Verify file permissions and directory structure

## Next Steps

After setting up the directory structure and configuration:

1. **Implement automation scripts** (`security/scripts/`)
2. **Configure CI/CD integration** for automatic updates
3. **Run initial security scans** to populate findings
4. **Customize remediation workflows** for your team

This security module provides a foundation for comprehensive security governance that scales with your project needs.
