In one implementation, an interposer library is installed on an embedded system or another type of computing system. The system may be configured to host web services or route data packets. A processor, executes processes of the system, and the interposer library intercepts data indicative of relationships of the processes. An access map is generated based on relationships of the processes of the system. The system is modified according to a set of procedures derived from the access map. The set of procedures may be derived by the processor or the access map. The set of procedures may be a minimum privilege solution that minimizes the privilege level of each process to a lowest privilege possible while maintaining the requisite functions of the process.
