Those of ordinary skill in the art will appreciate that the elements and algorithm steps of the examples described in connection with the embodiments disclosed herein may be embodied in electronic hardware, computer software, or combinations of both, and that the components and steps of the examples have been described in a functional general in the foregoing description for the purpose of illustrating clearly the interchangeability of hardware and software. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the implementation. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
The SQL is a Structured Query Language (Structured Query Language), is a special purpose programming Language, is a database Query and programming Language, and is used for accessing data and querying, updating and managing a relational database system.
Java Database Connectivity (JDBC) is an application program interface in Java language that specifies how client programs access databases, providing methods such as querying and updating data in databases.
The invention particularly relates to a method for screening decoration patterns and requests based on jdbc, which comprises the following steps of:
in the method of the invention, the server filters the user information. The information of the user access page, session (including login data) and the like can be intercepted.
S101, extracting access information and adding the access information into a judgment process queue;
in the step, before the access terminal is connected with the database, the address port and the identity information of the database which is requested to be accessed are sent to the server through the Jdbc port; the server verifies the identity information of the access terminal; and matching the identity information of the access terminal with the database requested to be accessed to determine whether the access authority is met.
S102, importing the access information into a server through a Jdbc port;
s103, the server judges whether the current access information is in compliance;
specifically, user information, sql information, access time information and database operation function information in the access information are obtained; extracting access time information in the access information; judging whether the access time information meets the requirement of an access time period;
and if the requirement of the access time period is met, judging whether the user information meets the access authority information.
And if the authority information is met, matching the authority information with the database operation function information, and judging whether the database operation function information meets the access authority.
And S104, if the rule is not met, the communication connection between the access terminal and the database is disconnected.
And acquiring the address and the user information of the current access terminal, and updating the address and the user information in the blacklist.
Based on the above method, the present invention further provides a screening system based on jdbc decorative pattern and request, as shown in fig. 2, including: a server 1 and a database 2;
the server is configured with a judgment process queue; receiving access information of an access terminal 3 through a Jdbc port, and configuring the access information to a judgment process queue; calling access information from the judgment progress queue according to a preset sequence to judge whether the current access information is in compliance; and if the compliance is met, the access terminal establishes communication connection with the database.
The server writes a new jdbc program to package the native jdbc through the decoration mode. Mainly decorate main class methods such as Driver, Connection, preparedState, State, etc. The contact server transmits the user information, the sql information and the function calling information to the monitoring server before and after the sql calling, and can also interrupt illegal operation to play a role in control.
The server is also used for configuring the access time period of the database and configuring different access time periods for different access authorities of the user.
Matching an access terminal with an access authority rule; and filtering the SQL access instruction in the access information, and matching the SQL access instruction with the access authority rule so as to execute the SQL access instruction matched with the access authority rule.
And the server configures a blacklist and configures the address information of the irregular access terminal into the blacklist.
Wherein the server can also access the server to determine whether the current application is available based on the Jdbc probe.
Further 301 when registering dirve for the first time, the monitored system requests the real database address port from the server.
302 when calling drive, decorated drive intercept connect method inquires the server whether the monitored system can execute sql
302 server replies and returns monitored system information
303 directly throwing an exception ending execution if the server disables the monitored link
The jdbc probe combines the sql information with the user information before the native jdbc executes the sql and sends it to the server for storage.
The server judges whether the current sql is in compliance
Interrupting operation if abnormal rules are directly thrown out
If compliance hands sql information to the native driver execution.
The switch authority does not need to be acquired, and the method is safe and reliable. The execution of sql can be monitored at any time, and illegal operations can be blocked in time. The context of the execution of the sql can be accurately monitored, and the user, the program and the line number of the execution of the sql can be positioned
Based on the method and the system, the invention also provides a readable storage medium with a jdbc decoration based mode and a request screening method, wherein the readable storage medium stores a computer program, and the computer program is executed by a processor to realize the steps of the jdbc decoration based mode and the request screening method.
The readable storage medium having the jdbc based decoration schema and the request screening method may take any combination of one or more readable media. The readable medium may be a readable signal medium or a readable storage medium. A readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination of the foregoing.
