Security Model

RedQuanta MCP implements a comprehensive multi-layered security architecture designed for enterprise penetration testing environments.

Security Layers

1. Network Layer

  • TLS Encryption: All communications encrypted
  • Network Segmentation: Isolated execution environments
  • Rate Limiting: DDoS protection and abuse prevention

2. Application Layer

  • Input Validation: Comprehensive parameter sanitization
  • Output Encoding: XSS and injection prevention
  • Authentication: API key and token-based access control

3. Logic Layer

  • Business Rule Enforcement: Security policy validation
  • Access Controls: Role-based permissions
  • Command Whitelisting: Only approved tools and arguments

4. Data Layer

  • Encryption at Rest: Sensitive data protection
  • Secure Storage: Audit logs and configuration files
  • Data Sanitization: PII removal and scrubbing

5. Infrastructure Layer

  • Container Isolation: Docker/Kubernetes sandboxing
  • Resource Limits: Memory, CPU, and disk quotas
  • Filesystem Jailing: Path traversal prevention

Threat Model

Identified Threats

Threat Likelihood Impact Mitigation
Command Injection High Critical ArgGuard validation
Path Traversal Medium High PathGuard boundaries
Privilege Escalation Low Critical Container isolation
Data Exfiltration Medium Medium Output filtering
DoS Attacks High Medium Rate limiting

Attack Vectors

Command Injection

# Blocked by ArgGuard
nmap 192.168.1.1; rm -rf /
nmap 192.168.1.1 && cat /etc/passwd

Path Traversal

# Blocked by PathGuard
../../../etc/passwd
..\\..\\windows\\system32\\cmd.exe

Security Controls

Input Validation

  • Regex Patterns: Semgrep-style injection detection
  • Allow Lists: Predefined command and argument validation
  • Type Checking: Parameter type enforcement

Command Execution

  • Sandboxed Environment: Docker container isolation
  • Limited Privileges: Non-root execution
  • Resource Constraints: CPU, memory, and time limits

Audit Logging

  • Complete Activity Tracking: All operations logged
  • JSONL Format: Structured audit trail
  • Tamper Protection: Append-only log files

Compliance

Standards Alignment

  • NIST Cybersecurity Framework: Identify, Protect, Detect, Respond, Recover
  • OWASP Top 10: Web application security best practices
  • CIS Controls: Critical security controls implementation

Regulatory Compliance

  • GDPR: Privacy-respecting data handling
  • SOC 2: Security and availability controls
  • ISO 27001: Information security management

Zero Trust Architecture

Principles

  1. Explicit Verification: Every request authenticated
  2. Least Privilege Access: Minimal required permissions
  3. Assume Breach: Comprehensive monitoring and response

Implementation

  • Multi-Factor Authentication: API keys + IP restrictions
  • Continuous Validation: Per-request security checks
  • Micro-Segmentation: Tool-level access controls

Security Configuration

Dangerous Mode

Special mode for exploitation tools: 

# Requires explicit enabling
export DANGEROUS_MODE=true

Jail Root Configuration

{
  "jailRoot": "/opt/redquanta/vol",
  "allowedDirs": ["tmp", "reports", "logs"],
  "readOnly": true
}

Command Policies

{
  "nmap": {
    "allowedArgs": ["-A", "-T4", "-sV"],
    "dangerousArgs": ["--script", "vuln"],
    "requiresDangerous": false
  }
}

Incident Response

Detection

  • Anomaly Detection: Unusual command patterns
  • Rate Limit Violations: Excessive request rates
  • Failed Authentication: Unauthorized access attempts

Response

  • Automatic Blocking: IP-based rate limiting
  • Alert Generation: Security team notifications
  • Forensic Logging: Detailed incident tracking

Recovery

  • Service Restoration: Graceful degradation
  • Data Integrity: Backup and restore procedures
  • Lessons Learned: Post-incident analysis

Security Testing

Regular Assessments

  • Penetration Testing: Annual external assessments
  • Vulnerability Scanning: Continuous automated scanning
  • Code Review: Security-focused code analysis

Compliance Auditing

  • SOC 2 Type II: Annual compliance audits
  • Internal Assessments: Quarterly security reviews
  • Third-Party Validation: Independent security assessments
