Ransomware invasion prevention system based on multiple schemes and application method

Abstract

A blackmail virus intrusion prevention system based on multiple schemes belongs to the technical field of Internet application and comprises a file access control module, a real-time monitoring and anomaly detection module, a multi-layer encryption mechanism module and a data backup and recovery module software unit which are installed in Internet equipment. The invention discloses a multi-scheme-based ransomware invasion prevention system and an application method. The system comprises six steps. The method can effectively prevent an unauthorized user process from accessing and modifying file data, ensures that a sensitive data file is not obtained by an illegal user and an illegal process, and reduces potential threats; through real-time monitoring, abnormal access behaviors can be recognized in time, potential security events can be quickly responded, the probability of successful intrusion of ransomware viruses is reduced, it is ensured that a user can obtain necessary access authority when needed, and meanwhile unnecessary risks are reduced; the security of a data key is protected by using multi-layer encryption, and data are backed up and encrypted regularly, so that the data can be quickly recovered after being attacked, and the service interruption time and the data loss risk are reduced.
