A compromised key can jeopardize DAO funds, governance, and operations. Let’s explore strategies to prevent, detect, and recover from key-related security incidents.
Preventing Key Compromise
Best Practices
- Use hardware wallets for signing transactions.
- Store private keys in cold storage for critical operations.
- Require multisig approvals for high-risk actions.
- Implement role-based access control (RBAC) to limit key usage.
- Regularly update firmware and security patches for wallet devices.
Common Pitfalls to Avoid
- Using a single signer for critical operations.
- Storing keys on hot wallets or online storage.
- Using the same private key for multiple roles.
Detecting Key Compromise Early
Best Practices
- Enable real-time monitoring for unusual activity.
- Set up alerts for large or unexpected transactions.
- Use circuit breakers (e.g., transaction delays or withdrawal caps).
- Conduct regular security audits of key management practices.
Common Pitfalls to Avoid
- Ignoring small unauthorized transactions (potential test attacks).
- Lack of on-chain analytics or monitoring tools.
- Failing to review access logs and activity patterns.
Recovery Strategies for Key Compromise
Best Practices
- Implement emergency multisigs to override compromised keys.
- Use time-locked transactions to allow rollback in case of an attack.
- Have backup keys stored securely and separate from primary keys.
- Utilize social recovery mechanisms for key restoration.
Common Pitfalls to Avoid
- No contingency plan for lost or stolen keys.
- Relying on a single recovery method (e.g., one backup keyholder).
- Slow response time after detecting a compromise.
Minimizing the Impact of a Compromised Key
Best Practices
- Implement tiered access levels (limit high-privilege key usage).
- Use ephemeral keys that expire after a set period.
- Set up modular governance to isolate risks (e.g., subDAOs with independent control).
- Enable automated kill switches to revoke compromised permissions.
Common Pitfalls to Avoid
- Granting all permissions to a single key or entity.
- Failing to revoke access quickly after a compromise.
- Using a rigid governance system that lacks emergency response flexibility.
Final Thoughts
- Prevent key compromise with secure storage and access control.
- Detect issues early with monitoring and alerts.
- Recover quickly with backup multisigs and emergency procedures.
- Minimize impact using tiered access and kill switches.
