Abstract: In one embodiment, a method is executed by a computer system. The method includes receiving information related to a platform-portable workload, the information comprising a data security policy expressed as digitally signed metadata. The data security policy specifies one or more data security features that any platform executing the platform-portable workload should implement. The method further includes validating the digitally signed metadata as originating from an issuer of the platform-portable workload. In addition, the method includes, responsive to successful validation of the digitally signed metadata, automatically determining whether a particular platform can satisfy the data security policy based, at least in part, on a comparison of the digitally signed metadata with data security attributes of the particular platform.

Abstract: A network interface device includes a memory and a processor operable to receive a malicious packet marker, store the malicious packet marker to the memory, monitor network data packets flowing in the network interface device, determine that a packet matches the malicious packet marker, and store log information from the packet to the memory.

Abstract: An information handling system includes a processor and a management controller separate from the processor. The management controller is operable to store an anti-virus program and a malicious marker detection program in a memory of the management controller, and to execute the malicious marker detection program. The malicious marker detection program operates to detect a state of a device of the information handling system, determine that the information handling system is under attack from a malicious program in response to detecting the state of the device, and send an alert to a management system coupled to the information handling system, the alert indicating that the information handling system is under attack from the malicious program.

Abstract: A serial communications adapter provides an interface to physical communications ports. A scheduler executing on the adapter schedules tasks at different priority levels, so that time-critical tasks are performed quickly enough to prevent data loss. Data to be transmitted or received through a communications port is stored in buffers on the adapter, and data and command communications between the adapter and the host system are preferably performed over a DMA channel.

Abstract: A terminal communications circuit that provides communication through a bus interface circuit to a network bus in accordance with the predetermined communications procedure, the terminal communications circuit including a communications interchange circuit that exchanges protocol signals with the bus interface circuit in response to commands received from a signal state controller that is resident in the terminal. The communications interchange circuit further provides communications state change information to the signal state controller to indicate the contents of the protocol signals from the bus information circuit. The signal state controller executes one of a plurality of program states to control communications over the network bus in accordance with predetermined communications procedure by providing commands to the communications interchange circuit in acordance with the program state that the signal state controller is currently executing.
