## Key Management Systems

Key Management Systems encompass the policies, hardware, and software used to create, store, and protect the cryptographic keys that secure a bridge. Given that these keys control access to bridge liquidity, their security is paramount.

Systems often utilize Hardware Security Modules to ensure keys are never exposed in plaintext. Key rotation policies are also implemented to minimize the impact of a potential compromise.

Effective management also includes rigorous auditing and access control lists. A failure in key management is often the root cause of the most catastrophic bridge hacks.

It is a blend of operational security and technical infrastructure.
