A method of operating a media scanner to protect a target machine from malware on a removable storage device is disclosed. The target machine and the removable storage device each include a respective data line, and the media scanner comprises a data switch. Data is scanned on the removable storage device with malware detection software of the media scanner via a first data path, the first data path comprising the data line of the removable storage device connected to the data line of the media scanner by the data switch in a first switching state. After the data has been scanned with the malware detection software, the data switch is operated to switch from the first switching state to a second switching state, thereby disconnecting the data line of the removable storage device from the data line of the media scanner and connecting the data line of the removable storage device to the data line of the target machine.

An industrial control system includes an encryption device, a decryption device and a mission-critical communication link connecting the encryption device to the decryption device. The encryption device is configured to send encrypted messages to the decryption device over the mission-critical communication link. The system includes a failure monitor configured to monitor for a failure of the encryption device or the decryption device, and, in the event of failure, to continue the sending of the messages to the decryption device but without encrypting the messages.

Mission-critical communication links for industrial control systems

A communication system includes an encryption device, a decryption device and a communication link connecting the encryption device to the decryption device. The encryption device is configured to send encrypted messages to the decryption device over the communication link. The system includes a failure monitor configured to monitor for a failure of the encryption device or the decryption device, and, in the event of failure, to continue the sending of the messages to the decryption device but without encrypting the messages.

Communication links

A microcontroller with a built-in self-healing function. A programmable memory stores a normal control routine. A processing unit is arranged to execute the normal control routine in order to provide output data on the output line. A danger signal input line which is connected to a logic unit and dedicated to communicating a danger signal to the logic unit. Processor and logic unit state lines are provided between the processing unit and the logic unit for communicating processor state data from the processing unit to the logic unit and communicating logic unit state data from the logic unit to the processing unit. An interrupt line between the logic unit and the processing unit is dedicated to communicating an interrupt signal from the logic unit to the processing unit.

Microcontroller

A computer implemented method of generating decision options. Sensor data is received from a plurality of sensors and presented visually to two or more users. Those users can then analyze the images and enter tag data which is received and stored along with the sensor data. The sensor and tag data are then input to a computer implemented decision support algorithm along with a stored operational plan. The algorithm then outputs one or more decision options which can assist a human decision maker in making a decision. The invention enables such a decision maker to make a decision quickly which complies with a previously stored operational plan and is likely to be correct since it is based on inputs from multiple human users. The invention is capable of being easily scaled to deal with a high volume of sensor data and a large number of users.

Collaborative decision making

Techniques to send and receive access commands are provided. The access commands may include an expected media position. The expected media position may be compared to an actual media position.

Access commands including expected media positions

Data processing apparatus comprising: a chunk store configured for containing specimen data chunks, a discrete manifest store, configured for containing at least one manifest that represents at least a part of a data set and that comprises at least one reference to at least one of said specimen data chunks, the processing apparatus being operable to process input data into input data chunks and to identify at least one manifest in the manifest store that includes at least one said reference to a said specimen data chunk corresponding to at least one of said input data chunks.

Data processing apparatus and method of processing data

Data processing apparatus comprising: a chunk store containing specimen data chunks, a manifest store containing a plurality of manifests, each of which represents at least a part of a data set and each of which comprises at least one reference to at least one of said specimen data chunks, a sparse chunk index containing information on only some specimen data chunks, the processor being operable to: process input data into input data chunks; identify manifests having at least one reference to one of said specimen data chunks that corresponds to one of said input data chunks and on which there is information contained in the sparse chunk index; and prioritize the identified manifests for subsequent operation.

Data processing apparatus comprising: a chunk store partitioned into a plurality of chunk sections, at least one section storing specimen data chunks, the processing apparatus being operable to: process input data into one or more input data chunks; identify a chunk section already containing a specimen data chunk corresponding to at least one input data chunk; and store the at least one input data chunk in another chunk section as a specimen data chunk if the identified chunk section has a predetermined characteristic.

Disclosed is a method of restoring a client device following failure of the client device, the client being connectable to a network comprising a server device. The method comprises saving to the server device a configuration state of the client device, the saved configuration state comprising client network interface configuration information, and a file of the client device. The method further comprises, following failure of the client computer, recording on a medium bootable on the client device program instructions for configuring the client device according to the saved configuration state, booting the client device from the bootable medium, configuring a network interface of the client device in accordance with the program instructions and the saved configuration state and restoring the file to the client device by copying over the network.
