With the rapid advancement of network information technology in China, computer networks have become deeply integrated into all aspects of socio-economic activities and daily life. However, this widespread integration has also led to an increasingly high incidence of cybersecurity issues. Threats such as hacker attacks, virus infections, phishing scams, and data breaches occur frequently, posing serious challenges to information security. Once a computer system encounters a network security incident, it can directly disrupt people's normal life and industrial production—resulting in the leakage of personal privacy, financial losses, paralysis of business operations, and even threats to national security and public interest. Therefore, it is essential for computer users to develop a strong awareness of network security management. This includes not only understanding basic protection knowledge but also actively adopting effective measures to prevent security risks. For instance, users should regularly update software and operating systems, install and maintain reliable antivirus programs, use strong passwords and multi-factor authentication, avoid clicking on suspicious links or downloading unverified attachments, and perform frequent data backups. At the same time, enterprises and institutions should establish comprehensive network security management systems, conduct regular security training and drills, and deploy advanced technical safeguards such as firewalls and intrusion detection systems. Only through a combination of heightened awareness and practical actions can the occurrence of computer network security problems be effectively reduced, thereby safeguarding personal, organizational, and national interests in the digital age.
