If you discover a security vulnerability in Symbiont, please report it responsibly:

1. Do NOT open a public GitHub issue for security vulnerabilities
2. Email security concerns to: [[email protected]] (replace with actual contact)
3. Include:
   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact
   • Suggested fix (if any)

• Acknowledgment: Within 48 hours
• Initial Assessment: Within 1 week
• Fix Timeline: Depends on severity
  • Critical: 24-72 hours
  • High: 1 week
  • Medium: 2-4 weeks
  • Low: Next release

Symbiont uses:

• Ed25519 for digital signatures (via ed25519-dalek)
• BLAKE3 for cryptographic hashing

The protocol assumes:

• Node IDs are cryptographically bound to key pairs
• Signatures are verified before processing messages
• Network transport provides basic integrity (TLS/encryption at transport layer)

1. Sybil Resistance: Requires external identity binding (e.g., stake, social graph)
2. Eclipse Attacks: Nodes should maintain diverse connections
3. Timing Attacks: Not currently hardened against timing side-channels

When deploying Symbiont:

1. Key Management

   • Store private keys securely
   • Rotate keys periodically
   • Use hardware security modules in production

2. Network Security

   • Use TLS for all network communications
   • Implement rate limiting
   • Monitor for anomalous patterns

3. Operational Security

   • Keep dependencies updated
   • Run cargo audit regularly
   • Enable logging and monitoring

We recommend running:

# Install cargo-audit
cargo install cargo-audit

# Run audit
cargo audit

# Install cargo-deny
cargo install cargo-deny

# Check for issues
cargo deny check

Security updates will be announced via:

• GitHub Security Advisories
• Release notes
• [Mailing list if applicable]
