This question tests understanding of traditional vs non-traditional security concepts. Traditional security concerns involve military threats that endanger sovereignty, independence and territorial integrity of the state. Non-traditional security concerns go beyond military threats to include threats affecting human existence (like diseases, environmental issues). The referent in traditional security is the state, while non-traditional security includes individuals and communities. Health epidemics like dengue threaten human existence, making them non-traditional concerns. Groups demanding nationhood or autonomy challenge territorial integrity and sovereignty, falling under traditional security. Migration and press criticism are not security threats.
