Description

Computer network safety controller

Technical Field

The utility model relates to a computer security technical field specifically is a computer network safety controller.

Background

The computer network security means that the confidentiality, integrity and usability of data are protected in a network environment by using network management control and technical measures. Computer network security includes two aspects, physical security and logical security. Physical security refers to the physical protection of system equipment and associated facilities from damage, loss, etc. Logical security includes the integrity, confidentiality, and availability of information. The computer network security not only comprises networking hardware and software for managing and controlling the network, but also comprises shared resources and rapid network service, so that the definition of the network security should consider all the contents related to the computer network. With reference to the computer security definition given by ISO, computer network security is considered to mean: hardware, software and data resources in a computer network system are protected and are not damaged, changed and leaked due to accidental or malicious reasons, so that the network system continuously, reliably and normally operates, and network services are normally and orderly. There are many factors that contribute to the insecurity of computer information, including human, natural and incidental factors. The human factors refer to that some lawless persons utilize bugs existing in a computer network or dive into a computer room, steal computer system resources, illegally acquire important data, tamper system data, damage hardware equipment and compile computer viruses. Human factors are the most threatening factors to the security of computer information networks. The computer network insecurity factors are mainly expressed in the following aspects: confidentiality, the property that information is not revealed to, or utilized by, unauthorized users, entities, or processes; integrity, the property of data that cannot be altered without authorization, i.e., the property of information that remains unmodified, undamaged, and lost during storage or transmission; availability, a feature that can be accessed and used on demand by an authorized entity. I.e. whether the required information can be accessed when required. Such as denial of service in a network environment, disruption of the normal operation of the network and related systems, etc., are all attacks on availability; controllability, which has control capability on the information transmission and content; the auditability provides basis and means for safety problems.

At present, a traditional network security controller cannot perform unique encryption operation on data of a computer, is difficult to achieve the effect of preventing internal information leakage of the computer well, brings potential safety hazards to information security of users, is easy to cause economic loss caused by the internal information leakage of the computer, brings inconvenience to the users, improves the situation and provides a computer network security controller.
