Security Policy

Enterprise Security Standards

WidgetBoard is built with enterprise-grade security as a foundational principle. This document outlines our security practices, compliance measures, and vulnerability reporting procedures.

Security Architecture

Zero-Trust Principles

• Authentication Required: All API endpoints require valid authentication tokens
• Least Privilege Access: Users and services operate with minimum necessary permissions
• Defense in Depth: Multiple layers of security controls
• Continuous Verification: Regular security audits and penetration testing

Data Protection

Encryption Standards

• In Transit: All data transmitted using TLS 1.3 or higher
• At Rest: Sensitive data encrypted using AES-256
• Key Management: Secure key rotation every 90 days
• Password Storage: bcrypt with minimum work factor of 12

Data Classification

Classification	Examples	Protection Level
Public	Marketing materials	Standard
Internal	User preferences	Encrypted in transit
Confidential	Email content	Encrypted at rest + transit
Restricted	Authentication tokens	Hardware security module

Authentication & Authorization

OAuth 2.0 Implementation

• Authorization Code Flow with PKCE for public clients
• Token Expiry: Access tokens expire after 1 hour
• Refresh Tokens: Rotated with each use, 30-day maximum lifetime
• Multi-Factor Authentication: Required for administrative access

Role-Based Access Control (RBAC)

Roles:
- Administrator: Full system access
- Power User: Widget creation and management
- Standard User: Widget usage only
- Guest: Read-only access to public widgets

API Security

Rate Limiting

• Per User: 100 requests per minute
• Per IP: 1000 requests per minute
• Burst Protection: 10 requests per second maximum

Input Validation

• All input sanitized against XSS attacks
• SQL injection prevention via parameterized queries
• Command injection prevention
• Path traversal protection

Content Security Policy (CSP)

default-src 'self';
script-src 'self' 'unsafe-inline' 'unsafe-eval';
style-src 'self' 'unsafe-inline';
img-src 'self' data: https:;
connect-src 'self' wss: https:;
font-src 'self';
object-src 'none';
base-uri 'self';
form-action 'self';
frame-ancestors 'none';

MCP (Model Context Protocol) Security

WebSocket Security

• WSS Protocol: All MCP connections use secure WebSocket (wss://)
• Connection Authentication: JWT tokens validated on connection
• Message Encryption: End-to-end encryption for sensitive data
• Connection Limits: Maximum 5 concurrent connections per user

Circuit Breaker Pattern

• Failure Threshold: 5 consecutive failures
• Timeout Duration: 30 seconds
• Reset Interval: 60 seconds after success

Microsoft Outlook Integration Security

Microsoft Graph API

• Delegated Permissions: Minimum required scopes only
• Token Storage: Encrypted in secure storage
• Token Refresh: Automatic with secure rotation
• API Rate Limiting: Respects Microsoft Graph throttling

Email Data Handling

• PII Protection: Personal information anonymized in logs
• Data Retention: Email content cached for max 24 hours
• Access Logging: All email access audited
• Consent Management: Explicit user consent required

Compliance Standards

GDPR Compliance

• Data Subject Rights: Right to access, rectification, erasure, portability
• Privacy by Design: Privacy controls built into every feature
• Data Processing Agreement: Available for enterprise customers
• Data Protection Impact Assessment: Conducted annually

ISO 27001 Alignment

• Information Security Management System (ISMS): Documented and maintained
• Risk Assessment: Quarterly risk reviews
• Incident Response: 24/7 security team
• Business Continuity: Tested disaster recovery procedures

OWASP Top 10 Protection

Risk	Mitigation
Injection	Parameterized queries, input validation
Broken Authentication	OAuth 2.0, MFA, secure session management
Sensitive Data Exposure	Encryption, secure key storage
XML External Entities	XML parsing disabled
Broken Access Control	RBAC, principle of least privilege
Security Misconfiguration	Automated security scans, hardened defaults
XSS	Content Security Policy, input sanitization
Insecure Deserialization	Validation, type checking
Using Components with Known Vulnerabilities	Automated dependency scanning
Insufficient Logging & Monitoring	Comprehensive audit trails

Security Monitoring

Logging

• Authentication Events: All login attempts logged
• Authorization Failures: Access denials tracked
• API Errors: Error rates monitored
• Security Events: Suspicious activity flagged

Alerts

Critical Alerts (Immediate Response):

• Multiple failed login attempts
• Unauthorized access attempts
• Data breach indicators
• Service outages

Warning Alerts (4-hour Response):

• Unusual traffic patterns
• Failed API calls spike
• Certificate expiration warnings

Metrics

• Security Event Rate: < 0.01% of total requests
• Mean Time to Detection: < 5 minutes
• Mean Time to Response: < 15 minutes
• Vulnerability Remediation: < 24 hours for critical

Vulnerability Management

Reporting Security Issues

DO NOT open public GitHub issues for security vulnerabilities.

Please report security vulnerabilities to: security@widgetboard.example.com

Include:

• Description of the vulnerability
• Steps to reproduce
• Potential impact
• Suggested mitigation (if any)

Response Timeline

• Acknowledgment: Within 24 hours
• Initial Assessment: Within 72 hours
• Patch Development: Based on severity
  • Critical: 24 hours
  • High: 7 days
  • Medium: 30 days
  • Low: Next release cycle

Disclosure Policy

• Coordinated Disclosure: 90-day embargo for patches
• Security Advisories: Published after patch deployment
• CVE Assignment: For confirmed vulnerabilities
• Hall of Fame: Recognition for responsible disclosure

Security Best Practices for Developers

Code Review Requirements

• Two Reviewers: All security-related code requires two approvals
• Security Checklist: Must be completed for each PR
• Automated Scanning: CodeQL and dependency checks required
• Manual Testing: Security features tested manually

Secure Development Lifecycle

1. Threat Modeling: Before design phase
2. Security Requirements: Defined with features
3. Secure Coding: Following OWASP guidelines
4. Security Testing: Automated and manual
5. Security Review: Before production deployment
6. Incident Response: 24/7 monitoring

Dependencies

• Automated Scanning: Daily dependency vulnerability scans
• Update Policy: Critical vulnerabilities patched within 24 hours
• Version Pinning: Exact versions in package-lock.json
• License Compliance: Only approved open-source licenses

Security Audit Trail

Audit Logging

All security-relevant events are logged with:

• Timestamp (UTC)
• User ID / IP Address
• Action performed
• Resource accessed
• Result (success/failure)
• Request/Response data (sanitized)

Retention

• Security Logs: 1 year
• Audit Trails: 7 years (compliance requirement)
• Access Logs: 90 days

Incident Response

Security Incident Classification

P0 - Critical: Active breach, data exposure

• Response Time: Immediate
• Team: Full security team + management

P1 - High: Vulnerability actively exploited

• Response Time: < 1 hour
• Team: Security team

P2 - Medium: Potential vulnerability identified

• Response Time: < 4 hours
• Team: Security engineer

P3 - Low: Security concern, no immediate risk

• Response Time: Next business day
• Team: Development team

Response Procedures

1. Detection: Automated monitoring or report received
2. Containment: Isolate affected systems
3. Eradication: Remove threat, patch vulnerability
4. Recovery: Restore services, verify security
5. Lessons Learned: Document and improve
