The aim of this speech is to explore effective ways of managing a cybersecurity team and enabling cybersecurity personnel to deliver higher efficiency. From the perspective of attack simulation, the cybersecurity operation is divided into three aspects: construction, team, and investment. Focusing on the pre, during, and post stages of an event, the program explores how to improve the procurement evaluation and decision-making efficiency of cybersecurity managers at the investment level, the cybersecurity resilience measurement and product verification efficiency of cybersecurity construction, and the on-site response capability and cybersecurity exercise efficiency of the cybersecurity team.
