Virus detection
View Patent ↗A server blade may comprise a processor and a network interface. The network interface can be configured to be connected to a network remote to the server blade. The server blade may be configured to detect a malicious code occurrence in traffic on the network. The server blade may be further configured as a field replaceable unit. Optionally, the server blade may further comprise an enclosure which encloses the processor.
1. A modular computer system comprising:
a carrier;
a plurality of information processing modules removably received in the carrier, each information processing module having a communications port connecting to a communications network internal to the carrier;
a switch connecting to the internal communications network to distribute information messages between the information processing modules and an external communications network;
a traffic inspection module removably received in the carrier and connecting to the internal communications network to receive an information message, wherein the traffic inspection module is configured to perform processing on the message to determine a safety status, and to forward the message toward a final destination via the internal communications network dependent upon the determined safety status; and
a management entity coupled to the plurality of information processing modules and the traffic inspection module, wherein the management entity is configured to detect a failure of the traffic inspection module, wherein, in response to detecting a failure of the traffic inspection module, the management entity is configured to inform the plurality of information processing modules of the failure.
2. The modular computer system of claim 1 , wherein the traffic inspection module is configured to determine the safety status on the basis of comparing the message to a pattern of a known unsafe code formulation.
3. The modular computer system of claim 1 , wherein the traffic inspection module is configured to determine the safety status on the basis of analysing the message for the presence of unsafe code instructions.
4. The modular computer system of claim 1 , wherein upon determination of an unsafe safety status, the message is processed to remove a cause of the unsafe status.
5. The modular computer system of claim 1 , wherein upon determination of an unsafe safety status, the message is deleted.
6. The modular computer system of claim 1 , wherein an unsafe safety status is allocated in the event of detection of malicious code within the message.
7. The modular computer system of claim 1 , wherein, in response to receiving an indication of a failure of the traffic inspection module, a traffic inspection function associated with the traffic inspection module is diverted to an alternative entity.
8. The modular computer system of claim 1 , wherein, in response to receiving an indication of a failure of the traffic inspection module, each of the plurality of information processing modules is configured to enter a defensive operational mode and perform a virus detection function.
