However, once the configuration file is read by an illegal user, the illegal user can directly log in to the database and modify the permission processing file stored in the database, thereby threatening the data security of the entire big data system by accessing the permission management module

Embodiment 1

[0051] This embodiment provides a method for network security management. Specifically, the method is applied to a large data cluster, where there are multiple principles (principles), where the principals may be servers, and the principals can communicate with each other. When the current cluster management platform manages the authority of each subject, it mainly stores the subject's authority processing file in the database. When any subject wants to use the authority processing file to operate, it needs to verify the authority processing file. That is, when the server detects that a subject uses the permission processing file to send a request, it obtains the permission processing file, and sends the permission processing file to the trusted encryption hardware module; Decryption operation: if the authority processing file can be decrypted, it means that the subject has the request authority, and respond to the subject's request. Since the trusted encryption hardware modul...

Embodiment 2

[0065] Based on the method described in Embodiment 1, this embodiment provides several specific ways to verify the subject.

[0066] Mode 1, before the server invokes the trusted encryption hardware module to decrypt the authority processing file, it also needs to perform identity verification on sending the request to determine whether the request is legal. Obtain a first judgment result according to the identity authentication information of the request; when the first judgment result shows that the request has legal identity authentication information, the trusted and encryptable hardware module decrypts the authority processing file . For example, in one of the application scenarios, the request has timed out, and the server may not respond to the timed-out request.

[0067] Method 2: After judging that the request is legal, the server also needs to judge whether the request has access rights, that is to say, verify the access rights of the request and obtain a second jud...

Embodiment 3

[0072] This embodiment provides a method for network security management.

Correspondingly, for the subject side, befo...

Abstract

The invention discloses a network security management method and a server. The method comprises the following steps: when detecting that one subject uses an authority processing file sending request, acquiring the authority processing file; transmitting the authority processing file to a trusted cryptographic hardware module; enabling the trusted cryptographic hardware module to decrypt the authority processing file; and using the decrypted authority processing file to respond to the request of the subject. The technical scheme of the embodiment of the invention adopts the trusted cryptographic hardware module to decrypt the authority processing file, so that the subject verifies the authority when calling the authority processing file, thereby improving the network security.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a network security management method and a server. Background technique [0002] At present, common big data systems generally use the user authority management module to manage user authority. In terms of security control of permissions by the permission management module, the security mechanism of the database itself is generally used to ensure security, for example, a user name and password are used to log in to the database for security verification. Usually, the user name and password of the database in the authority management module are saved in the database configuration file in the form of plain text. However, once the configuration file is read by an illegal user, the illegal user can directly log in to the database and modify the permission processing file stored in the database, thereby threatening the data security of the entire big data system by accessing...
