An organized assembly of resources and procedures united and regulated by interaction or interdependence to accomplish a set of specific functions. In information security a system encompasses the hardware software networks facilities data and personnel that work together to provide computing capabilities. Systems can range from simple workstations to complex enterprise environments spanning multiple locations. System security is addressed in frameworks like NIST SP 800-53 ISO 27001 and various regulatory standards. Organizations protect systems through layered security controls configuration management monitoring and ongoing assessment. For example a hospital might implement comprehensive security for its electronic health record system including access controls encryption automated patching system hardening configuration baselines monitoring tools backup processes and disaster recovery capabilities all documented in a system security plan and regularly tested.
