Emerging technology has ushered information and cognitive space as primary battlefields in the ambiguous “grey zone” which exist between peace and war. The evolving threats presented by weaponised advanced cyber capabilities, artificial intelligence, big data analytics and social media platforms which allow adversaries to disrupt systems, manipulate perceptions and alter decisions has forced re-writing of the strategic concepts and recalibrating of the existing capabilities. In the information battle space disruption, disinformation, distortion and deception are ways to secure national objectives through coercion and influence. The contemporary conflicts illustrate how technology amplifies the stealth, reach and complexity of grey zone tactics and also the importance of strategic communication, narrative control, media management and cognitive resilience. This technology enabled evolution has profound strategic implications: deterrence frameworks must adapt to non-kinetic threats and national security architectures must integrate protection of cognitive resilience. Ultimately, technological progress magnifies both the opportunities and risks in grey zone warfare. There is need to examine and take stock of entire gamut of these high-tech operations with their impact in order to correctly assess technological gaps, institutional shortcoming and lack of appropriate frameworks so as to fix the shortcomings and integrate all resources for achieving desired dominance while competing in the cognitive domain.
