Information security means that the information system (including hardware, software, personnel, data, physical environment and its infrastructure) is protected from being changed, destroyed or leaked by accidents or malicious reasons, and the system can run continuously and reliably without interrupting information services, and finally realize business continuity. Information security is divided into two levels: narrow security and broad security, which can train senior information security professionals engaged in computer, e-commerce, communication, e-government, e-finance and other fields. Information security mainly includes the following five aspects: the need to ensure confidentiality, integrity, authenticity, unauthorized copying and the security of parasitic systems. Information security itself covers a wide range, including how to prevent teenagers from browsing bad information and prevent the disclosure of confidential and personal information of commercial enterprises. The information security system under the network environment is the key to ensure information security, including various security protocols, computer security operating system, security mechanisms (digital signature, message authentication, data encryption, etc. ), and security systems such as UniNAC and DLP will threaten global security as long as there are security loopholes.
