What is the security of computer information system?

The factors that can lead to the insecurity of computer information systems include software systems, hardware systems, environmental factors and human factors. Software system: The software system generally includes system software, application software and database parts.

Computer informationThe information security of the system is the core, which refers to preventing information property from being intentionally or accidentally leaked, changed, destroyed or made information identified and controlled by illegal systems, and to ensure the confidentiality, integrity, availability and controllability of information.

The definition of the Computer Management and Supervision Department of the Ministry of Public Security of China is that computer security refers to the security of computer assets, that is, computer information system resources and information resources are not threatened and harmed by natural and man-made harmful factors.

Simply put, the security of the management system refers to the security and confidentiality measures taken by the management system to protect the management system from natural disasters and deemed damage from outside the system, and to prevent illegal users from illegally using system resources, especially information.

What is the security and reliability of computer management information system

Information security Information security includes operating system security, database security, network security, anti-virus, access control, encryption and authentication. It is used to ensure that information will not be illegally read, modified and leaked. Adopting advanced and reliable security technology can reduce the vulnerability of computer information systems.

Reliability in computer security attributes refers to the system completing the specified functions under specified conditions and within the specified time. Computer security is to protect computer hardware, software and data from being destroyed, changed or leaked due to accidental or malicious reasons.

Reliability in computer security attributes means that the system completes the specified functions under specified conditions and within the specified time.

Reliability in computer security attributes refers to the completion of the specified functions of the system under the specified conditions and within the specified time. The security attributes of the computer include: the security of the data stored by the computer and the security of the computer hardware. That is, it is necessary to ensure the confidentiality, authenticity, integrity, unauthorized copying and the security of the parasitic system of the information.

The meaning of information security mainly refers to the integrity, availability, confidentiality and reliability of information. Information system security includes: physical security. Physical security mainly includes environmental security, equipment security and media security. Effective technical precautions should be taken in the system center room that handles secret information.

What are the basic characteristics of the security of the information system?

1. The five characteristics of information security are: Integrity refers to the characteristics of non-modification, non-destruction and non-loss in the process of transmission, exchange, storage and processing, that is, maintaining the information as it is, so that the information can be correctly generated, stored and transmitted, which is the most basic security feature.

2. Basic characteristics of information security: Extensiveness: Society has begun to enter the era of universal network. The Internet connects the country's information system. Network users can connect to the Internet at any network access point in the world and access other network users.

3. The three basic characteristics of computer information system security are ()A. Physical security, network security, data security B. Confidentiality and integrity.

What is information system security?

1. Information security means that information is not illegally or maliciously stolen, tampered with and destroyed in the process of transmission, processing and storage.

2. Information security means that the information system (including hardware, software, data, people, physical environment and its infrastructure) is protected from accidental orIt is destroyed, changed and leaked due to malicious reasons. The system operates continuously and reliably and normally, and the information service is not interrupted, which finally achieves business continuity.

3. Network security includes two aspects: on the one hand, it includes physical security, which refers to the protection of tangible items such as communications, computer equipment and related facilities in the network system, so that they are not wet by rain. On the other hand, it also includes what we usually call logical security. Including information integrity, confidentiality and availability, etc.

4. Information security: The information security of computer information system is the core, which refers to preventing information property from being intentionally or accidentally leaked, changed, destroyed or made information identified and controlled by illegal systems to ensure the confidentiality, integrity, availability and controllability of information.

5. Information system security is to put forward security requirements in terms of technology, management, engineering and personnel throughout the life cycle of the information system to ensure the confidentiality, integrity and availability of the information system, and reduce security risks to an acceptable level, so as to ensure that the system realizes the mission of the organization. .
