Security is at the core of Interspace. We take the protection of user data and privacy extremely seriously. This document outlines our security practices and how to report vulnerabilities.

We provide security updates for the following versions:

• End-to-End Encryption: Sensitive data encrypted using AES-256-GCM
• Secure Key Storage: iOS Keychain for credential storage
• Certificate Pinning: SSL/TLS certificate validation
• Biometric Authentication: Face ID/Touch ID support
• Secure Communication: All API calls over HTTPS
• Input Validation: Comprehensive input sanitization
• Memory Protection: Sensitive data cleared from memory after use
• Jailbreak Detection: Runtime integrity checks
• Code Obfuscation: Critical security logic protected

• Minimal data collection
• Local-first architecture
• No tracking or analytics without consent
• Clear data retention policies
• User-controlled data export/deletion

Please do not report security vulnerabilities through public GitHub issues.

1. Email us at security@interspace.app with:

   • Type of vulnerability
   • Affected components
   • Steps to reproduce
   • Potential impact
   • Suggested mitigation (if any)

2. Encrypt sensitive details using our PGP key:

   -----BEGIN PGP PUBLIC KEY BLOCK-----
   [PGP Key will be provided here]
   -----END PGP PUBLIC KEY BLOCK-----
   

3. What to expect:

   • Acknowledgment within 48 hours
   • Regular updates on progress
   • Credit in security advisories (if desired)
   • Potential bug bounty reward

• Detailed description of the vulnerability
• Proof of concept code (if applicable)
• Impact assessment
• Your contact information
• Preferred disclosure timeline

• Quick response: Within 48 hours
• Open communication: Regular status updates
• Fair assessment: Thorough investigation
• Timely fixes: Based on severity
• Recognition: Credit for responsible disclosure

We use CVSS v3.1 for scoring:

• Remote code execution
• Authentication bypass
• Crypto wallet compromise
• Mass data exposure

Response time: 24-48 hours

• Privilege escalation
• Significant data leakage
• Authentication weaknesses

Response time: 3-5 days

• Limited data exposure
• Denial of service
• Session vulnerabilities

Response time: 7-14 days

• Minor information disclosure
• UI security issues

Response time: 30 days

We offer rewards for responsibly disclosed vulnerabilities:

Rewards depend on impact and quality of report

• First reporter of unique vulnerability
• Clear, reproducible report
• Responsible disclosure followed
• No public disclosure before fix

• Social engineering
• Physical attacks
• Denial of service
• Spam or social media attacks
• Vulnerabilities in third-party services

• Security-focused code review for all PRs
• Automated security scanning
• Dependency vulnerability checks
• Static code analysis

1. Never commit secrets

   • Use environment variables
   • Add to .gitignore
   • Rotate if exposed

2. Validate all inputs

   // Good
   guard let email = emailField.text?.trimmingCharacters(in: .whitespacesAndNewlines),
         isValidEmail(email) else {
       throw ValidationError.invalidEmail
   }
   
   // Bad
   let email = emailField.text!

3. Use secure APIs

   • Prefer modern cryptographic APIs
   • Avoid deprecated security functions
   • Use iOS security frameworks

4. Handle sensitive data carefully

   // Clear sensitive data
   defer {
       password.removeAll()
       privateKey.removeAll()
   }

• No hardcoded secrets
• Input validation implemented
• Secure communication used
• Error messages don't leak info
• Authentication checks in place
• Authorization properly implemented
• Sensitive data encrypted
• Security tests added

We conduct regular security assessments:

• Quarterly: Dependency scanning
• Bi-annually: Penetration testing
• Annually: Full security audit
• Continuous: Automated scanning

Audit reports available upon request for partners.

Our API implements these security headers:

Strict-Transport-Security: max-age=31536000; includeSubDomains
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block
Content-Security-Policy: default-src 'self'

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <false/>
</dict>

// Secure storage example
let keychain = KeychainManager()
try keychain.store(password, for: "user_password")

// Biometric protection
let context = LAContext()
context.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics,
                      localizedReason: "Authenticate to access your wallet")
