A connectome is a map of neural connections in a nervous system. It shows which neurons link to which others, and sometimes the strength or direction of those links. In biology, connectomes help researchers understand how circuits are organized and how information may flow through the brain.
In cyber security, connectomes matter whenever neural data, brain-computer interfaces, or neuromorphic systems are involved. A complete or high-resolution connectome can be sensitive intellectual property or private biological data, so attackers may target it for theft, tampering, or espionage. Defenders care about access control, encryption, logging, and integrity checks to protect these datasets. The term can also appear in research on brain-inspired AI, where network structure is analyzed much like a system diagram. A connectome is a map, not a behavior explanation, so security analysts must avoid treating structure as proof of function or intent.
