When it is necessary to import virus databases, system patches, etc. into confidential information systems, the method that can be used is to burn a read-only CD through an intermediate machine. Read-only optical discs undergo permanent physical changes, and the recorded information can only be read out and cannot be modified; read-only optical discs are mainly used for data that is written once without modification, and data cannot be appended to the optical disc.
The operating environment of this tutorial: Windows 10 system, Dell G3 computer.
Confidential information system mainly refers to computer equipment used to process confidential information or a confidential information exchange network system used to realize internal office automation. Generally speaking, confidential information systems refer to computer systems that have certain security and confidentiality needs and requirements. In accordance with national mandatory standards and regulations, computer systems that reach a certain security level are called confidential information systems.
When it is necessary to import virus databases, system patches, etc. into confidential information systems, the method that can be adopted is to burn a read-only CD through an intermediate machine.
Read-only optical discs are discs that are re-pressed in large quantities after the manufacturer produces the master disc at a high cost. This type of molded recording causes permanent physical changes to the disc, and the recorded information can only be read out and cannot be modified. Read-only optical discs are mainly used for data that is written once without modification. Data cannot be appended to the optical disc. It has a layered structure. The top layer is a metal film (such as aluminum) that records information, and the lower layer is glass or organic. Clear plastic like glass.
Expand knowledge:
The difference between confidential information systems and public information systems is mainly reflected in four aspects:
First, the information content is different. The information stored, processed and transmitted by confidential information systems involves state secrets and other sensitive information, and the scope of knowledge should be strictly controlled; the information stored, processed and transmitted by public information systems cannot involve state secrets.
Second, facilities and equipment standards are different. The security and confidentiality facilities and equipment of confidential information systems must comply with national confidentiality standards; the security and confidentiality facilities and equipment of public information systems should also meet certain technical standards, but they are not required to comply with national confidentiality standards.
Third, the testing and approval requirements are different. Confidential information systems must meet security and confidentiality requirements and comply with national confidentiality standards. They must undergo security and confidentiality testing, evaluation, review and approval before being put into use. Public information systems also need to undergo relevant testing before being put into use, but the purpose and requirements of the testing are different.
Fourth is the different usage permissions. Confidential information systems must strictly control access rights; public information systems are open and can be used as long as certain access conditions are met.
