SYSTEMS AND METHODS FOR COMBINED PHYSICAL AND CYBER DATA SECURITY

Methods and systems for protecting computer systems against intrusion. The disclosed techniques detect intrusions by jointly considering both cyber security events and physical security events. In some embodiments, a correlation subsystem receives information related to the computer system and its physical environment from various information sources in the cyber domain and in the physical domain. The correlation subsystem analyzes the information and identifies both cyber security events and physical security events. The correlation subsystem finds cyber security events and physical security events that are correlative with one another, and uses this correlation to detect intrusions.
