According to reports, many airlines such as Air China, China Eastern Airlines, China Southern Airlines, Juneyao Airlines, and Spring Airlines operate flights normally, and public services such as high-speed rail and banks remain stable and unaffected by major system technology failures. Professionals in the cybersecurity industry indicate that these companies’ ability to protect themselves may be due to three reasons. For example, the industry widely uses domestic terminal security protection software like 360; domestic security manufacturers do not completely rely on automated upgrading of cybersecurity products but rather pay more attention to the overall operation of the system and team building; and in recent years, regular cybersecurity attack-defense drills have been conducted to simulate real network attack scenarios, discover potential safety products and system vulnerabilities, and test and enhance the protective capabilities of critical infrastructure.
