Access Control Logic Review

Access control logic review involves auditing the mechanisms that restrict which users or contracts can execute specific functions within a protocol. In financial systems, improper access control can allow unauthorized parties to pause contracts, withdraw collateral, or change critical system parameters.

Auditors examine ownership structures, role-based access control, and administrative privileges to ensure they are properly restricted and managed. This includes checking for hardcoded addresses, reliance on single-point-of-failure admin keys, and the lack of multi-signature requirements for sensitive actions.

Ensuring robust access control is a critical step in mitigating the risk of insider threats and external hacks. It is a fundamental aspect of secure system architecture in the context of programmable money.
