First of all, the confidentiality of classified information system refers to the ability to protect important information from illegal acquisition. In order to achieve confidentiality, we need to adopt a variety of means to strengthen security, such as cryptography, access control technology and security audit technology.
For example, for cryptography, the commonly used methods are symmetric encryption, asymmetric encryption and hash algorithm, and for access control technology, role-based access control and attribute-based access control can be adopted. These technologies can effectively improve the security level of classified information systems.
Secondly, the integrity of confidential information system refers to the tamper-proof and tamper-proof protection ability of important information. Integrity is an important part of information security. After the data integrity is attacked, it will lead to information distortion and even irreparable consequences. Therefore, confidential information systems need to use digital signatures, hash values and other means to ensure the integrity of data.
Finally, the availability of classified information system refers to the ability to ensure the normal operation of the system. In order to achieve availability, backup and redundancy technology must be adopted to ensure that important data will not be lost when the system fails. At the same time, appropriate measures should be taken to prevent malicious attacks and human misoperation from affecting classified information systems.
In view of the importance of classified information system, we must attach great importance to it and implement it as an important policy. This requires various measures, including technical means and management mechanism. At the same time, enterprises and individuals also need to strengthen their own security awareness in order to protect the security of confidential information more effectively.
The protective measures for confidential information systems are as follows
1. Overall control measures: safety management, personnel control, special communication, physical protection, militarized management, emergency preparedness, etc.
2. Network security measures: network boundary protection, penetration defense, access control, intrusion detection, data encryption, etc. At the same time, users need to be educated and trained in safety to improve their safety awareness and preventive ability.
3. Monitoring and auditing measures: monitoring and auditing the use, access and operation of confidential information systems, and timely discovering and handling security risks and problems.
