Social cybersecurity is an emerging field that focuses on the intersection of cyber threats and human behavior, aiming to understand and mitigate the impact of cyber-mediated changes in social, cultural, and political outcomes. It highlights the use of technology by state and nonstate actors to manipulate beliefs and narratives on a global scale, affecting warfare strategies, such as in the case of Russian information warfare. Information warfare is now central to hybrid conflicts, where attacking an enemy’s trust, values, and social cohesion can weaken them before any physical military action occurs. Unlike traditional cybersecurity, which targets information systems, social cybersecurity involves “hacking” humans and the societal structures that bind them, often leveraging psychological manipulation, marketing tactics, and targeted information operations. This field blends multiple disciplines, including sociology, psychology, political science, and computational social science, and is crucial for national defense, as its impact on social cohesion can have strategic consequences akin to traditional warfare. The article underscores the need for military leaders to understand these dynamics as information warfare becomes a central element of global conflict.
