A computer-implemented method and system for protecting a host computer in a computer network from security threats uses local security-relevant data for the host computer, as well as global security-relevant data for other components in the computer network downloaded from a security information plane system to the host computer, to determine a security threat to the host computer. When a security threat is determined to be a legitimate threat, a security alert is issued, and then an action is initiated in response to the security alert.

Security protection for a host computer in a computer network using cross-domain security-relevant information

System and method for managing security-relevant information in a computer network uses a security information plane (SIP) manager to which different types of security-relevant data are uploaded from components in the computer network and from which networkwide aggregated security information produced from the security-relevant data is download to a global security controller. The downloaded networkwide aggregated security information is used by the global security controller to control security applications running in the computer network.
