In the modern world, there is no doubt that Internet is playing an increasingly important role in our daily lives. Not only does it bring us information, but it also makes our lives convenient. However, the security of the Internet is always a hot potato that we have been facing with for years. Many netizens realize the fact that their privacy is suffering from violation and threat. In their daily life, they are disturbed by the property losses because of the leak of the bank account. Why does the security of the Internet suffer from violation and threat? For one thing, some network operators' ignorance of users' interest is the first factor to blame, for they sell the private information of the users to pursue their own profits frequently. For another, our country lacks relevant laws enacted by the government, which means that the internet users' right has not been officially protected. What's more, people do not Install firewall and update their antivirus soft-wares in time. From my perspective, there is no denying that we should pay attention to Internet safety. Firstly, the government should step up supervision. Secondly, the netizens should improve the awareness of self-protection to avoid such violation and threat. The last but not least, moral education should be put emphasis on. Only when we raise public moral awareness can these problems be avoided completely. 本文来源：https://www.wddqw.com/doc/e06db1e9b84ae45c3a358c05.html
