Explanation

In systems security engineering, the security principle of modularity provides isolated functions and data. Modularity means dividing a system into well-defined logical units that have clear boundaries and interfaces. This helps to reduce complexity, improve maintainability, and enhance security. By isolating functions and data, modularity prevents unauthorized access, limits the impact of failures, and facilitates testing and verification. Modularity also supports the principle of least privilege, which grants the minimum access required to perform a function.
