🛡️ PolicyGuard Security & Governance

[haasonsaas]

Overview

Implement comprehensive security and governance system with fine-grained policy enforcement, audit trails, and compliance controls.

Problem

Current sandbox is basic and doesn't provide fine-grained security controls. No governance framework for enterprise deployment or compliance requirements.

Solution

Build enterprise-grade policy enforcement:

Policy Engine

• Path Sandboxing: Restrict file system access by path patterns
• Network Controls: Allowlist external connections
• Command Filtering: Prevent dangerous operations
• Secret Protection: Detect and prevent secret exposure
• Resource Limits: CPU, memory, disk, network quotas

Policy Definition (TOML)

[policy.secure]
name = "High Security Profile"

[policy.secure.filesystem]
allowed_paths = ["src/", "tests/", "docs/"]
forbidden_paths = [".env", "*.key", "secrets/"]
max_file_size = "10MB"

[policy.secure.network]
allowed_domains = ["api.github.com", "registry.npmjs.org"]
forbidden_ips = ["169.254.169.254"]  # AWS metadata
block_private_networks = true

[policy.secure.commands]
allowed_commands = ["cargo", "npm", "git"]
forbidden_patterns = ["curl", "wget", "rm -rf"]

[policy.secure.secrets]
scan_patterns = ["api[_-]key", "password", "token"]
redaction_mode = "full"

Governance Features

• Audit Trails: Complete record of all actions
• Compliance Reports: SOC2, GDPR, HIPAA alignment
• Role-Based Access: Different policies per user role
• Approval Workflows: Human gates for sensitive operations
• Incident Response: Automatic alerting and containment

PolicyGuard Implementation

struct PolicyGuard {
    policies: HashMap<String, Policy>,
    audit_log: AuditLog,
    secret_scanner: SecretScanner,
}

impl PolicyGuard {
    async fn enforce(&self, operation: &Operation, policy: &str) -> Result<Decision>;
    async fn audit(&self, operation: &Operation, result: &OperationResult) -> Result<()>;
    async fn detect_violations(&self, content: &str) -> Result<Vec<Violation>>;
}

Enterprise Features

• LDAP/SSO Integration: Enterprise authentication
• Policy Templates: Industry-standard compliance
• Centralized Management: Policy distribution and updates
• Monitoring Dashboards: Real-time security metrics
• Integration APIs: Connect to SIEM, compliance tools

Implementation Plan

1. Design policy definition language and engine
2. Build path and network sandboxing
3. Add secret detection and redaction
4. Implement audit logging and trails
5. Add compliance reporting framework
6. Build centralized policy management

Success Criteria

• Block 100% of policy violations
• Complete audit trail for all operations
• Zero secret leaks in generated content
• Compliance report generation in <1min
• Policy updates deploy in <5min across fleet

Compliance Standards

• SOC 2 Type II: Audit trails, access controls
• GDPR: Data protection, right to deletion
• HIPAA: Healthcare data handling (where applicable)
• ISO 27001: Information security management

Timeline

6-8 weeks for core engine, 12-16 weeks with enterprise features

Dependencies

• ToolGraph for operation interception
• Audit infrastructure
• Secret management system
