Security

AIO Sandbox implements multiple layers of security to ensure safe code execution and protect the host environment while providing powerful development capabilities.

Security Architecture

Container Isolation

AIO Sandbox runs in a Docker container providing:

  • Process isolation: Contained processes cannot access host system
  • Network isolation: Controlled network access
  • File system isolation: Limited access to host file system
  • Resource limits: CPU, memory, and disk usage restrictions

Sandbox Fusion Runtime

Code execution is further secured through Sandbox Fusion:

  • Memory limits: Per-execution memory restrictions
  • CPU time limits: Prevent infinite loops and resource abuse
  • Import restrictions: Limited access to system libraries
  • File system boundaries: Restricted file access within container

Access Controls

File System Security

File operations respect standard Unix permissions:

  • User permissions: Regular user access by default
  • Sudo access: Optional elevated privileges (configurable)
  • Path validation: Prevents directory traversal attacks
  • Content sanitization: Input validation and sanitization
{
  "file": "/safe/path/file.txt",
  "sudo": false,
  "content": "Sanitized content"
}

Network Security

Network access is controlled at multiple levels:

  • Container networking: Isolated network namespace
  • Outbound filtering: Optional egress restrictions
  • Port binding: Controlled service exposure
  • Proxy isolation: Internal proxy for development preview

Authentication & Authorization

Development Mode

Default configuration for development environments:

  • No authentication: Direct access for development
  • Local access: Typically bound to localhost
  • Temporary sessions: Terminal sessions with timeout

Production Considerations

For production deployments, implement additional security:

# Docker Compose with security
version: '3.8'
services:
  aio-sandbox:
    image: ghcr.io/agent-infra/sandbox:v1
    security_opt:
      - no-new-privileges:true
    read_only: true
    tmpfs:
      - /tmp
      - /var/tmp
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - DAC_OVERRIDE

Configuration Security

Environment Variables

Secure configuration through environment variables:

# Disable sudo access
SANDBOX_ENABLE_SUDO=false

# Enable rate limiting
SANDBOX_RATE_LIMIT=true

# Restrict network access
SANDBOX_NETWORK_RESTRICTED=true

# File operation limits
SANDBOX_MAX_FILE_SIZE=10MB
SANDBOX_MAX_FILES_PER_REQUEST=100

Resource Limits

Configure resource restrictions:

# Memory limits
SANDBOX_MAX_MEMORY=1GB

# CPU limits  
SANDBOX_MAX_CPU_TIME=30s

# Disk space limits
SANDBOX_MAX_DISK=5GB

# Process limits
SANDBOX_MAX_PROCESSES=50

API Security

Rate Limiting

Built-in rate limiting protects against abuse:

  • File operations: 100 requests per minute
  • Code execution: 10 requests per minute
  • Terminal connections: 5 concurrent sessions
  • Browser operations: 20 requests per minute

Input Validation

All API endpoints perform input validation:

  • Path validation: Prevent directory traversal
  • Content sanitization: Remove malicious content
  • Size limits: Prevent resource exhaustion
  • Type validation: Ensure correct data types

Error Handling

Secure error handling prevents information disclosure:

  • Generic error messages: Don't reveal system details
  • Sanitized stack traces: Remove sensitive paths
  • Rate limit responses: Prevent enumeration attacks
  • Logging security: Sensitive data not logged

Browser Security

VNC Security

VNC access is configured for development security:

  • Password protection: Optional VNC password
  • Local binding: Bind to localhost by default
  • Session timeout: Automatic disconnect after inactivity
  • Screen locking: Optional screen lock when idle

Chrome DevTools Protocol

CDP access is secured:

  • Local access only: Not exposed externally
  • Session management: Isolated browser contexts
  • Resource limits: Memory and CPU restrictions
  • Extension restrictions: Limited browser extensions

Monitoring & Auditing

Security Logging

AIO Sandbox logs security-relevant events:

  • Authentication attempts: If authentication is enabled
  • File access: Sensitive file operations
  • Command execution: Shell commands and code execution
  • Network connections: Outbound connection attempts

Health Monitoring

Monitor security status:

# Check security status
curl http://localhost:8080/v1/sandbox/security

# Monitor active sessions
curl http://localhost:8080/v1/shell/sessions

# Check resource usage
curl http://localhost:8080/v1/sandbox/resources

Best Practices

Deployment Security

  1. Network Isolation: Deploy in isolated network segments
  2. Reverse Proxy: Use authenticated reverse proxy for external access
  3. TLS Termination: Implement HTTPS at load balancer/proxy level
  4. Firewall Rules: Restrict network access to necessary ports only

Development Security

  1. Code Review: Review any code executed in sandbox
  2. Dependency Scanning: Scan dependencies for vulnerabilities
  3. Regular Updates: Keep container image updated
  4. Backup Strategy: Regular backups of important data

Runtime Security

# Example: Secure file operations
def safe_file_operation(file_path, content):
    # Validate file path
    if not is_safe_path(file_path):
        raise SecurityError("Invalid file path")
    
    # Validate content size
    if len(content) > MAX_FILE_SIZE:
        raise SecurityError("File too large")
    
    # Sanitize content
    clean_content = sanitize_content(content)
    
    # Perform operation
    return write_file(file_path, clean_content)

Compliance & Standards

Security Standards

AIO Sandbox follows industry security standards:

  • OWASP Guidelines: Web application security best practices
  • Container Security: CIS Docker Benchmark compliance
  • Secure Coding: SANS secure coding standards
  • Privacy Protection: Data minimization principles

Audit Trails

Maintain audit logs for compliance:

  • User actions: All API calls and operations
  • System events: Security-relevant system events
  • Data access: File and data access logging
  • Configuration changes: Security setting modifications

Incident Response

Security Monitoring

Monitor for security events:

  • Unusual activity: Unexpected API usage patterns
  • Resource abuse: Excessive resource consumption
  • Access attempts: Unauthorized access attempts
  • System anomalies: Unusual system behavior

Response Procedures

  1. Detection: Automated monitoring and alerting
  2. Assessment: Evaluate security impact
  3. Containment: Isolate affected containers
  4. Recovery: Restore from clean state
  5. Lessons Learned: Update security measures

Security Updates

Container Updates

Keep AIO Sandbox updated:

# Pull latest security updates
docker pull ghcr.io/agent-infra/sandbox:latest

# Check for vulnerabilities
docker scan ghcr.io/agent-infra/sandbox:latest

Vulnerability Management

  • CVE Monitoring: Track security vulnerabilities
  • Patch Management: Apply security patches promptly
  • Dependency Updates: Keep dependencies current
  • Security Testing: Regular security assessments

Reporting Security Issues

If you discover a security vulnerability:

  1. Do not create a public GitHub issue
  2. Email security concerns to: security@agent-infra.com
  3. Include detailed information about the vulnerability
  4. Allow reasonable time for response and fix
