This speech aims to explore how to effectively manage a cybersecurity team and improve the efficiency of cybersecurity personnel. Through attack simulations, we will divide cybersecurity operations into three aspects: construction, team, and investment, to comprehensively improve the efficiency and effectiveness of the cybersecurity team. Starting from the pre, during, and post stages of incidents, we will explore how to improve the procurement evaluation and decision-making efficiency of cybersecurity managers at the investment level, and improve the resilience measurement and product verification efficiency of cybersecurity construction. At the same time, we will examine in detail how to enhance the on-site response capabilities and cybersecurity exercise efficiency of the cybersecurity team to better respond to various cybersecurity events and risks. Finally, we will study how to combine the overall capabilities of the cybersecurity team with the strategic goals of the enterprise to achieve long-term development and success. These strategies will help to improve the overall capabilities and effectiveness of the cybersecurity team and ensure the security of the enterprise.
