1. Information security means that the hardware, software and data in the information network and its system are protected from accidental or malicious reasons that are destroyed, changed or leaked, and the system runs continuously, reliably and normally, and the information service is not interrupted. Information security mainly includes the following five aspects, that is, to ensure the confidentiality, authenticity, integrity, unauthorized copying of information and the security of the parasitic system.

2. Information security is a comprehensive discipline involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines Information security refers to the protection of the hardware, software and information of the system, and the continuous normal operation and service. The essence of information security is to protect information systems and information resources from various threats, interference and destruction, that is, Ashui guarantees the security of information.

The main goal is to prevent information from being identified and controlled by unauthorized leakage, alteration, destruction or illegal systems, and to ensure the confidentiality, integrity, availability, controllability and auditability of information (the five characteristics of information security). **In the "Regulations on the Security Protection of Computer Information Systems", it is pointed out that the security protection of computer information systems shall ensure the security of computers and their related supporting equipment and facilities (including networks), the security of the operating environment, the security of information, and the normal performance of computer functions, so as to maintain the safe operation of computer information systems.

The International Organization for Standardization (ISO) defines information security as the establishment and adoption of quiet technical and managerial protection for data processing systems to protect computer hardware, software, and data from destruction, alteration, and leakage due to accidental and malicious reasons.

Is it appropriate for a science girl to choose the major of information security?

OK. What is the outlook for this profession in recent years? Which is better than computer science and technology?

The information security major is the most difficult major in the undergraduate, and the computer is better.

How about the computer major of Hebei Agricultural University.

First: Hebei Agricultural University Computer Technology National Comprehensive Ranking,
