The access amount may include one or more of the following times: database access times, database table access times, database/data table operation times and database table field access times; the number of database accesses may be displayed after the database port and the database name, for example: 192.168.10.34 db 25000 hr 12, 192.168.10.34 db 25000 supply 15, 192.168.10.34 db 25000 account 18, 192.168.10.34 db 25000 fs 0. The number of database table accesses can be as follows: user 28, hr. offer 19, hr. health 50, supply. address 20 or supply. detail 0. User select 28 may be the number of database/table operations and user ID 28 may be the number of database table field accesses.
Step S102, determining the data assets with the access quantity meeting a first condition as heat data;
in the embodiment of the present invention, the first condition may be that the access amount is greater than a preset access threshold, and the preset access threshold is customized by a manager and assigned with a specific numerical value. For example, the preset access threshold is 3000, and the data assets with access amount larger than 3000 are determined as the heat data. Or, the first condition may be that a heat value of the data asset is determined according to the access amount, and the data asset with the heat value greater than a preset threshold is determined as the heat data. In practical applications, a part of the database is often accessed by a person skilled in the art, while another part of the database is not accessed for various reasons, in which case the frequently accessed database needs to be determined, and then the frequently accessed database needs to be protected.

In the embodiment of the invention, the database table of the database operation can be extracted from the database operation instruction, and a mapping relation exists between the database table and the database.
Further, before the method proceeds to step S101, the method further includes: acquiring information of data assets in a preset time period, and specifically operating as follows:
scanning the script by using the port to obtain a scanning result;
labeling the port based on the scanning result to obtain a labeled port;

In the embodiment of the invention, the start-stop IP address and the port range are configured in the scanning script, and the port scanning script is used for scanning the IP of the database and the port of the database. For example, the database IP is 192.168.10.211521, 192.168.10.253306, or 192.168.10.345000. The scan results include, but are not limited to, database IP, database port, and database name. Labeling a manufacturer default port issued by a database management system according to a scanning result, and then confirming the labeled port by a manager in a distributed mode; for unlabeled database ports, the administrator supplements and confirms in a distributed fashion. For example, the port for the tag may be 192.168.10.211521 oracle, 192.168.10.253306 my sql or 192.168.10.345000 db 2.
The information of the data asset is the content of the scanning result, which is also called as the information of the database, including but not limited to the database IP, the database port and the database name. The database name may refer to an application name, and in the 192.168.10.34 db 25000 Hr description, the database name may refer to Hr. The invention utilizes the mode of automatically identifying the port and manually confirming to comprehensively search the data assets in the IT network environment, thereby ensuring comprehensive and omission-proof performance.
