## Module Security Interfaces

Module security interfaces are the standardized entry points and validation checks that govern how different modules within a protocol interact. By enforcing strict security protocols at the boundary of each module, developers can ensure that one module cannot be exploited to compromise the integrity of another.

These interfaces often include access control checks, input validation, and rate limiting to prevent unauthorized or malicious calls. As protocols become more modular, these interfaces serve as the primary line of defense against cross-module attacks.

Designing secure interfaces requires a deep understanding of the potential attack vectors that could be used to exploit the interactions between modules. By prioritizing the security of these boundaries, developers can build modular systems that are as secure as they are flexible.
