This paper conceptualizes security literacy as an educational competence linked to societal resilience and national defence preparedness. It combines theoretical discussion with an interpretative use of recent Czech survey material from primary and secondary schools. The Czech case suggests a mismatch between the perceived importance of security-related competencies and their fragmented institutional presence in formal education. The article argues that schools should be understood as part of long-term civilian preparedness and recommends clearer curricular anchoring, stronger teacher preparation, and more systematic practical instruction.
The paper examines contemporary national defence challenges arising from the interconnection of digital technologies, social dynamics, and global tensions. Using interdisciplinary analysis and policy review, it explores how cyber threats and emerging technologies shape resilience and security outcomes. The findings highlight the critical role of societal trust, strategic communication, and coordinated international frameworks such as NATO and EU initiatives. The study implies that effective defence strategies require integrated technological, social, and policy dimensions. The paper contributes original insights into comprehensive security approaches that enhance both national and collective resilience in the digital age.
