Abstract:
1. A security system for a computer network, the network having a plurality of devices connected thereto, the security system comprising: (a) a security subsystem implemented on a first computer, the security subsystem being connected to at least some of the devices in the network, the security subsystem configured to monitor activities of the at least some devices on the network and detect attacks on the at least some devices; (b) a master system implemented on a second computer which is different from the first computer, the master system monitoring the integrity of the security subsystem and registering information pertaining to attacks detected by the security subsystem, the master system including a pseudo-attack generator which generates attacks on the network, the security subsystem detecting such attacks when functioning properly, the master system comparing the pseudo-attacks made on the network to the attacks actually detected by the security subsystem, the master system thereby determining whether the integrity of the subsystem has been compromised; and (c) a first secure link connected between the security subsystem and the master system, the master system monitoring the integrity of the security subsystem and receiving the information pertaining to the attacks through the first secure link.
