A correct statement should include the following points:
1. The classified information system is based on the classified communication network and mainly includes network equipment, data storage system and encryption system.
2. Confidential information systems usually need to adopt encryption measures to ensure that sensitive information is not illegally obtained or tampered with.
3. When planning, designing, developing, maintaining and using classified information systems, we should abide by a series of national laws, regulations and standards on confidentiality and strictly protect the security and confidentiality of classified information.
4. The use of classified information systems requires corresponding licenses and qualifications, and strict authorization and identity verification are required in the process of use.
The construction and management of classified information system needs professional personnel and technical support, and it is an essential part of the national information security system.
Application scope of information system:
Classified information systems are widely used, mainly involving information processing and transmission in national security, military affairs, politics, diplomacy, economy, science and technology and other fields. In government agencies, military, scientific research institutes, financial institutions, telecom operators and other places, it is possible to involve the application of classified information systems.
The construction and management of classified information systems need a high degree of confidentiality and security awareness, and the leakage, loss or attack of classified information systems may cause immeasurable losses. Therefore, in the operation and management of classified information system, besides the application of encryption technology, it is necessary to set up multi-level security measures in each link, such as identity authentication, access control, audit trail and so on.
With the continuous development and application of information technology, the security level of classified information systems is constantly improving and the requirements are more stringent. Therefore, the construction and management of classified information systems will still face great challenges in the future, and new technologies and methods need to be continuously introduced to improve the security and confidentiality of classified information systems.
In a word, the construction and management of classified information system is a complex and important work, which needs to fully consider multiple factors such as confidentiality, security and efficiency, strengthen technical support and management guarantee, and ensure that it plays an important role in national security and information construction.
