This paper explores how ASEAN member states are adopting a human security approach to combat cyber terrorism. Traditional cybersecurity—centered on infrastructure protection and technical solutions—proves insufficient against complex threats like online radicalization. The human security perspective reframes cyber terrorism as a social and human challenge, focusing on the protection of individuals and communities. Through a qualitative case study approach, drawing on literature, surveys, and focus groups with cybersecurity stakeholders, the research finds that although the human security concept is acknowledged, its policy integration remains limited. Technical measures still dominate, but emerging initiatives emphasize community-based prevention, trust-building, and inclusion. A major obstacle is the lack of trust in digital spaces. Human-centered strategies require individuals to feel safe online, yet this is undermined by cyber threats and harmful actors. Moreover, coordination between state and non-state actors is weak. Governments emphasize legal and technical responses, while civil society organizations focus on psychosocial support and community resilience. Nevertheless, opportunities for collaboration are emerging. Public–private partnerships and local interventions offer potential for aligning efforts and enhancing the impact of cyber terrorism prevention. A shift toward inclusive, sustainable security models may help address the underlying drivers of extremism and foster long-term resilience in ASEAN societies.
