The greatest threat to world peace and security in recent times are those happening through the cyberspace. The sophistication and devastations of these threats recorded through cyberattacks across the world in recent times has brought to the fore the vulnerabilities of both strong and weak nations. Today warfare, whether political or economic between nations or states have metamorphosed from the conventional modes into a cyberwarfare which is more deadly and this has severely jeopardized global security and peace of humanity. This study examined how global security and peaceful coexistence can be enhanced through the sharpening of cybersecurity architecture. In the study, some incidences of cyberattacks across the world were examined, responses of the global community were reviewed, African nations experiences of cybersecurity threats were discussed among others. Standing on the game theory, (Non-zero Sum), the study suggested an integrated approach to formulating and implementing workable global cybersecurity architecture where the interests of all stakeholders are factored in and protected.
