On September 11th, the opening ceremony of the 2023 Guangdong Provincial Cybersecurity Promotion Week was held in Guangzhou, with simultaneous events such as the Cybersecurity Summit Forum and Cybersecurity Expo. It is reported that during this year's network security promotion cycle in Guangdong Province, various exciting activities will be held, including a network security competition, an award-winning Q&A on network security knowledge, a survey on high-quality development of network security in Guangdong, a collection of network security promotional works, and the promotion of network security at the grassroots level. This will promote network security knowledge to the public, enhance national awareness and protection skills of network security, build a strong network security barrier, and safeguard a clear cyberspace. On the spot of the Science Popularization Initiative Immunization Summit Forum for Academicians of the Chinese Academy of Engineering, Shen Changxiang, Wu Jiangxing, Academicians of the CAE Member and other network security experts and industry representatives shared around the topics of the integrated development of network security education technology industry, security protection of key information infrastructure, data security, personal information protection, and so on, to provide advice and suggestions for promoting high-quality development of the network information industry. A secure and trustworthy network security system is the foundation for building a strong cyber power, "Shen Changxiang said. In the era of the Internet of Things, network attacks will extend from digital space to physical space. We should create a secure and trustworthy industrial system and build an active immune protection system for cyberspace security. Shen Changxiang said that currently, most network security systems are mainly composed of firewalls, intrusion detection, and virus killing. "However, traditional 'blocking and killing' is difficult to deal with human attacks and is more easily exploited by attackers. Shen Changxiang introduced that active immune trusted computing is a new computing mode that simultaneously performs security protection. It uses passwords as genetic antibodies to implement functions such as identity recognition, state measurement, and confidential storage, timely identifying "oneself" and "non oneself" components, thereby destroying and rejecting harmful substances entering the body. From passive defense to active immunity, the trusted computing model has changed the traditional one-sided computing model that only emphasizes computational efficiency and does not emphasize security protection, equivalent to cultivating immune capabilities for network information systems. Due to the unpredictability, extreme uncertainty, and rapid evolution of potential cybersecurity threats or attacks, it is extremely difficult to achieve the goal of ensuring that digital products in cyberspace are free from vulnerabilities and security defense is' not penetrating the bottom and breaking the defense '. Wu Jiangxing pointed out that in addition to providing users with' bodyguard style 'protection services on the user end, it is also necessary to start from the manufacturing end of electronic and network products, When designing and manufacturing software and hardware for digital products, network security is considered an important indicator, and efforts are made both in the manufacturing industry and on the user side. Guangdong is a major province in the internet and digital economy. How to build a network security barrier? Shen Changxiang suggests that we can further promote secure and trustworthy network products and services, create a secure and trustworthy industry system, build a secure and trustworthy network security barrier, comprehensively enhance network security guarantee capabilities, and escort the vigorous development of network security technology and industry. The Citizen Check in Expo learned about online fraud prevention information. "It turns out that AI face changing fraud is one thing." At the Cybersecurity Expo, the AI face changing display area of the Guangdong Pavilion attracted many citizens' attention. Many citizens expressed that the project experience was very fun and also felt that
