Security
This document defines the security principles, policies, implementation standards, and operational practices that protect MHMD Studio, its users, client data, infrastructure, and AI systems. Security is considered a core engineering requirement rather than an optional enhancement.

Purpose
Security exists to protect:
- Users
- Clients
- Data
- Infrastructure
- APIs
- AI systems
- Business continuity
Every feature should be evaluated from a security perspective before deployment.
Security Philosophy
Security should be:
- Proactive
- Layered
- Practical
- Maintainable
- Automated
- Continuously monitored
The objective is to reduce risk without unnecessarily harming usability.
Core Principles
Follow these principles:
- Least Privilege
- Defense in Depth
- Zero Trust
- Secure by Default
- Fail Securely
- Minimize Attack Surface
- Continuous Monitoring
- Privacy by Design
Threat Model
The platform should be designed to resist:
- Unauthorized access
- Credential theft
- Injection attacks
- Cross-Site Scripting (XSS)
- Cross-Site Request Forgery (CSRF)
- Broken authentication
- Data leakage
- API abuse
- Denial of Service
- Supply chain attacks
Security reviews should evolve as the platform grows.
Authentication
Authentication is managed using:
- Supabase Auth
- JWT
- Secure HTTP-only cookies
- OAuth providers (future)
Passwords should never be stored by MHMD Studio.
Authorization
Authorization should use Role-Based Access Control.
Initial roles:
- Public
- User
- Admin
Permissions should be explicit.
Never rely on frontend authorization.
Session Management
Sessions should:
- Expire automatically.
- Support secure refresh.
- Use encrypted cookies where appropriate.
- Support logout across devices (future).
Sensitive actions may require re-authentication.
Password Policy
For accounts using passwords:
- Strong password requirements.
- Password hashing handled by authentication provider.
- Password reset through secure workflows.
Never store plaintext passwords.
Multi-Factor Authentication
Future versions should support:
- TOTP
- Passkeys
- Hardware security keys
Administrative accounts should require MFA whenever practical.
Secrets Management
Secrets include:
- API keys
- Database credentials
- OAuth secrets
- AI provider keys
- Encryption keys
Requirements:
- Store only in environment variables or dedicated secret managers.
- Never commit secrets to version control.
- Rotate secrets periodically.
Environment Separation
Maintain separate environments:
- Development
- Preview
- Production
Production secrets must never be used in development.
Transport Security
All production traffic must use HTTPS.
Enable:
- TLS
- HSTS
- Secure cookies
Reject insecure connections where possible.
Data Encryption
Encrypt:
- Data in transit
- Sensitive data at rest
Where appropriate, encrypt highly sensitive application data before storage.
Input Validation
Validate every external input.
Validation should occur:
- Client side
- API layer
- Server layer
Never trust client input.
Output Encoding
Escape user-generated content before rendering.
Protect against:
- XSS
- HTML injection
- Script injection
Prefer framework-native escaping.
SQL Injection
Prevent SQL injection by:
- Parameterized queries
- ORM safeguards
- Input validation
Never construct SQL through string concatenation.
CSRF Protection
Protect state-changing requests.
Use:
- CSRF tokens where applicable
- SameSite cookies
- Secure authentication flows
Rate Limiting
Protect:
- Authentication endpoints
- Contact forms
- AI endpoints
- Search endpoints
- Administrative APIs
Rate limits should be proportional to risk.
File Upload Security
Before accepting uploads:
- Validate file type.
- Validate MIME type.
- Validate size.
- Sanitize filenames.
- Reject executable files.
Future versions should include malware scanning.
Content Security Policy
Deploy a strict Content Security Policy.
Limit:
- Scripts
- Frames
- External resources
Allow only trusted origins.
Security Headers
Enable:
- Content-Security-Policy
- X-Frame-Options
- X-Content-Type-Options
- Referrer-Policy
- Permissions-Policy
- Strict-Transport-Security
Headers should be reviewed periodically.
Logging
Security events should include:
- Authentication failures
- Authorization failures
- Rate limit violations
- Administrative actions
- Unexpected exceptions
Logs should never expose sensitive information.
Monitoring
Continuously monitor:
- Failed logins
- Suspicious requests
- API abuse
- Server errors
- Traffic anomalies
Monitoring should trigger alerts for critical events.
Dependency Security
Before introducing a dependency verify:
- Active maintenance
- Known vulnerabilities
- License compatibility
- Community adoption
Dependencies should be updated regularly.
Supply Chain Security
Protect against dependency attacks by:
- Locking package versions
- Reviewing updates
- Running vulnerability scans
- Verifying package sources
AI Security
Protect AI systems against:
- Prompt injection
- Data leakage
- Model abuse
- Excessive resource consumption
AI should never expose confidential information from internal systems.
Privacy
Collect only necessary data.
Users should understand:
- What data is collected.
- Why it is collected.
- How long it is retained.
- How it can be removed.
Privacy policies should remain transparent.
Backup Security
Backups should be:
- Encrypted
- Tested
- Access controlled
- Stored securely
Backup access should remain restricted.
Incident Response
Every security incident should include:
- Detection
- Containment
- Investigation
- Recovery
- Documentation
- Prevention
Lessons learned should improve future defenses.
Security Audits
Regularly perform:
- Dependency audits
- Permission reviews
- Infrastructure reviews
- API reviews
- Authentication reviews
Document findings and remediation.
Compliance
Where applicable, align with:
- GDPR principles
- OWASP Top 10
- WCAG (security-related accessibility)
- Industry best practices
Compliance should support users rather than become a checkbox exercise.
Security Checklist
Before deployment verify:
- HTTPS enabled.
- Secrets secured.
- Authentication tested.
- Authorization tested.
- Input validated.
- Output escaped.
- CSP configured.
- Security headers enabled.
- Dependencies reviewed.
- Logs functioning.
- Monitoring configured.
- Backups verified.
Future Security Roadmap
Future improvements may include:
- Hardware-backed authentication
- Continuous penetration testing
- Automated threat detection
- Secret rotation automation
- Infrastructure policy as code
- Zero-trust networking
- Security scorecards
Security should mature alongside the platform.
Final Principle
Security is a continuous engineering practice.
Every new feature should improve or preserve the security posture of the platform.
