    • A test system for a managed cloud computing environment may have a management system that may recruit devices in the cloud and outside the cloud to perform a test on a cloud based application. Each device may execute an agent that connects the device to several cloud services for messaging, data collection, and executable code storage. The management system may identify and gather the devices, then cause the devices to execute a test by sending commands through the messaging service. The devices may access executable code for the specific tasks of a test through the code storage service, and as the devices complete tasks for the test, the devices may publish results in the data collection service. The test system enables any type of scenario to be implemented, including operations that can only be performed inside and outside the managed cloud environment.

    • Embodiments provide an application layer security proxy that protects substation automation systems. The application layer security proxy inspects a received, inbound data packet at the application layer, and either drops the data packet, forwards the data packet, or processes the data packet rather than dropping it in order to maintain the communications network connection, the later two according to a predefined role-based access control policy. The application layer security proxy calculates a round trip time for each reply to a received, inbound data packet and observes the bandwidth usage from the amount of bytes transmitted. Round trip time and bandwidth usage are used to detect abnormal communication traffic.
