Cyberwarfare launched by state and non-state actors is a severe national security challenge for governments in the world today. To deal with cyber attacks in which tools evolve rapid and yet complicated, governments make various efforts on national and international levels for cyber defense. Learning from others to improve self-performance is also necessary.

This short essay analyzes the cyber defense capabilities of the UK. The author first introduces the cyber defense strategic concept that the UK holds, suggesting that it does not take a passive posture, rather, it has a proactive and preemptive stance. The author then describes the cyber defense units and forces following the aspects of intelligence, military and those that combine both. To be specific, the UK National Cyber Security Centre, as well as the National Cyber Force, are individually examined. Together, they form a web-like defensive framework. The author summarizes the UK models and experiences and then offers clues as recommendations for those interested in considering appropriate ways of improvement in the Taiwan context.
