Network security is an important line of defense to protect the security of personal and corporate information. The Chinese government attaches great importance to network security and has formulated a series of laws and regulations to combat cybercrime activities and protect citizens' personal information from infringement. Common cyber attack methods include phishing emails, malware, social engineering, etc., which are all illegal acts. We call on the majority of Internet users to raise their security awareness, do not click on unknown links, do not download unknown software, change complex passwords regularly, and use two-factor authentication and other measures to protect their account security. At the same time, we firmly support the Chinese public security organs in combating cybercrime in accordance with the law and maintaining a clean environment in cyberspace.
