The advent of the neuro-digital age has completely changed our perspective on cybersecurity. No more limited to the sphere of network, endpoint, or even biometric identity, threat landscape has been extended to an absolutely new field, the mind. Neuroscience and cybersecurity are converging at an increasingly fast rate, giving rise to a completely different field, neuro-cybersecurity. Rewrite the abstract: The convergence of neuroscience and cybersecurity marks a fundamental paradigm shift. Brain-computer interfaces and neuroadaptive systems have transformed cognition into both a vulnerability and a defense mechanism, making mental confidentiality and brain integrity central to modern security. Unlike conventional cyberattacks targeting software and devices, emerging cognitive threats seek to alter perception and decision-making directly through neural telemetry, a capability already demonstrated in military research. Technologies such as EEG, fNIRS, and MEG enable real-time monitoring of cognitive states like stress and fatigue, reducing human-factor errors in security operations. However, neurobehavioral analytics capable of detecting deception through brainwave activity raise serious ethical concerns around privacy, consent, and neuro-profiling. Jurisdictional inconsistencies in neural data regulation create geopolitical complications, particularly since neural data cannot be reset if compromised. Building public trust requires transparent governance, privacy-preserving BCIs, and broad neuro-literacy.
