We provide security updates for the following versions of the Space Data Communication Analysis Project:

For security-related issues, please do NOT create a public GitHub issue. Instead, please report security vulnerabilities through one of the following channels:

• Email: Send details to security@project-domain.com
• Private Security Report: Use GitHub's private vulnerability reporting feature
• GPG Encrypted Email: For highly sensitive issues, use our GPG key (available on request)

Please include the following information in your security report:

1. Description: A clear description of the vulnerability
2. Impact: Assessment of the potential impact
3. Reproduction Steps: Detailed steps to reproduce the issue
4. Affected Components: Which parts of the system are affected
5. Proposed Solution: If you have suggestions for fixing the issue
6. Contact Information: How we can reach you for follow-up questions

We are committed to responding to security reports promptly:

• Initial Response: Within 24 hours of receiving the report
• Triage: Within 72 hours, we will assess the severity and impact
• Resolution Timeline:
  • Critical vulnerabilities: 7 days
  • High severity: 14 days
  • Medium severity: 30 days
  • Low severity: 90 days

We follow a responsible disclosure process:

1. Private Resolution: We work with reporters to fix issues privately
2. Coordinated Disclosure: Public disclosure after fixes are available
3. Credit: Security researchers are credited for their discoveries (unless they prefer anonymity)

• Encryption: Post-quantum cryptography for all sensitive communications
• Authentication: Mutual TLS for all network communications
• Integrity: HMAC verification for all messages
• Access Control: Role-based access control for system components
• Audit Logging: Comprehensive logging of all security-relevant events
• Intrusion Detection: AI-based anomaly detection for network traffic

• Code Reviews: All code changes require security-focused reviews
• Static Analysis: Automated security scanning with Bandit and CodeQL
• Dependency Scanning: Regular vulnerability scanning of dependencies
• Container Security: Docker images scanned with Trivy
• Secrets Management: No secrets stored in code or configuration files

This project follows NASA security standards for space applications:

• NIST Cybersecurity Framework: Implementation of appropriate controls
• NASA Security Requirements: Compliance with NASA-STD-1006 and related standards
• CCSDS Security Standards: Implementation of space communication security protocols
• FIPS 140-2: Use of validated cryptographic modules where required

1. Signal Interception: All communications are encrypted with post-quantum algorithms
2. Jamming/Interference: Fault tolerance mechanisms provide redundant communication paths
3. Replay Attacks: Nonce-based encryption prevents message replay
4. Man-in-the-Middle: Mutual authentication prevents unauthorized intermediaries

1. Input Validation: All external inputs are validated and sanitized
2. SQL Injection: Parameterized queries prevent injection attacks
3. Cross-Site Scripting: Output encoding prevents XSS in web interfaces
4. Buffer Overflows: Memory-safe languages and practices prevent overflows

• Dependency Updates: Automated weekly scanning and updates for security patches
• Container Updates: Base images updated regularly for security fixes
• Notification System: Security alerts through GitHub Security Advisories

For critical security updates:

1. Hotfix Releases: Emergency releases for critical vulnerabilities
2. Patch Documentation: Clear documentation of security fixes
3. Migration Guides: Instructions for updating existing deployments

• Quarterly Reviews: Internal security assessments
• Annual Penetration Testing: Third-party security testing
• Code Audits: External security code reviews for major releases
