Infrastructure Hardening

Infrastructure hardening is the process of securing the underlying systems, such as servers, nodes, and network configurations, that support a protocol. Even if the smart contracts are secure, a vulnerability in the node infrastructure or the front-end interface can lead to a compromise.

Hardening involves disabling unnecessary services, implementing strict firewall rules, using secure key management, and ensuring that all software is patched against known vulnerabilities. In the context of crypto, this also includes protecting the RPC nodes that the protocol interacts with.

A robust infrastructure is the foundation upon which secure applications are built; without it, the most secure code in the world remains vulnerable to peripheral attacks.
