Protecting users from harmful information (aggression, terrorism, pornography, extremism, etc.) on the Internet has become more topical in recent years in terms of information abundance and has affected the socio-economic processes around the world. There are various scientific approaches and technologies to protect against malicious information, to identify their source, to determine exactly which web content is useful or harmful. The article provides information on the essence and application benefits of a widely used content-filtering method to distinguish between harmful and useful web content, and defines the levels of filtering of web content. The essence of static and dynamic approaches for blocking the websites that contain malicious content and the difference between them are highlighted. The purpose of the study is to demonstrate the importance of effective use of the content-filtering method and to highlight the importance of cleaning the web resources from malicious content in solving information security, cybercrime and other problems existing in the virtual space (pp.80-88).

Keywords:Web content filtering, information security, malicious data, filtration level, URL filtering.
