For convenience of description, the server is referred to as a database and the client is referred to as a database client in this embodiment. When the packet grabbing is performed, the grabbing of the data packet can be performed through a probe, and the probe can be arranged on a database. The probe is a program or a plug-in capable of monitoring a network data packet, and the probe can acquire all network data traffic accessing a predetermined network address by monitoring the predetermined network address, and then can further process the network data traffic.
The captured data packets may include two data packets, one is a data packet sent by the database client to the database, and the other is a data packet returned by the database to the database client. The data packet sent by the database client to the database may carry SQL statements (simply referred to as statements) and also may carry session information (including network address information of the database client, where the network address information may include an IP address and a port number). The data packet sent by the database to the database end may carry a result set, where the result set is a result returned after an operation is performed in the database according to the SQL statement. The data packet sent by the database to the database end may further include information about the execution failure of the SQL statement, and these information may also be used to test the auditing effect of the auditing program on the execution failure.
In the present embodiment, a performance testing method of an auditing program is provided, and fig. 1 is a flowchart of the performance testing method of the auditing program according to an embodiment of the present application, as shown in fig. 1, and the steps included in fig. 1 are explained below.
Step S102, acquiring a data packet for interaction between a database client and a database, and saving the acquired data packet as a sample data packet;
step S104, obtaining a test case, wherein the test case carries a requirement for testing an audit program;
step S106, generating data information for testing according to the requirement, wherein the data information for testing is carried in a data packet;
for example, the requirement is used to indicate an audit situation of an audit program when a plurality of database clients access a database at the same time, at this time, IP addresses and port numbers of N database clients are generated according to the number N of the plurality of database clients, and the sample data packet is copied into N groups of data packets, where the IP addresses and port numbers of each group of data packets in the N groups of data packets are the same, and the IP addresses and port numbers of the N database clients correspond to the N groups of data packets one to one; and sending the generated N groups of data packets to the auditing program. Optionally, the requirement obtains the number of data packets required for performing the stress test from the requirement in the case that the requirement indicates that the requirement is used for performing the stress test, and determines the number of each group of data packets in the N groups of data packets according to the number of the required data packets; sending N groups of data packets to the auditing program simultaneously for the stress test.
For example, an SQL statement template is configured in advance, wherein a plurality of SQL statements used between a database client and a database are stored in the SQL statement template; and the requirement is used for indicating the test auditing program to acquire all SQL sentences from the SQL sentence template under the condition of processing different SQL sentences, calculating the number M of all SQL sentences, generating copies of M sample data packets according to the number M of all SQL sentences, replacing the SQL sentence in the copy of one sample data packet by each SQL sentence in the SQL sentence template, and generating M test data packets.
Step S108, searching the position of the data information for testing in the sample data packet, and replacing the original data information in the sample data packet by using the data information for testing according to the position;
and step S110, sending the replaced sample data packet as a test data packet to an auditing program so as to test the auditing program.
Through the steps, the problem that statements and audit elements are single when the audit program is tested through the playback data packet is solved, and therefore the comprehensiveness of the audit program is improved.
In order to prevent the data packet for testing from being considered as an abnormal data packet by the auditing program, in an optional implementation manner, the length of a sample data packet after original data information in the sample data packet is replaced by the data information for testing may be obtained; updating the length to a length field of the sample data packet; calculating a check value according to the updated sample data packet after the length field; updating the check value to a check value field of the sample data packet to generate the data packet for testing; and sending the data packet for testing to the auditing program.
In an optional embodiment, the number of the test data packets may be multiple, that is, when the number of the test data information is multiple, the sample data packet is copied to obtain sample data packet duplicates corresponding to the number of the test data information; and replacing the original data information in one sample data packet copy with each data information in the data information to obtain a plurality of data packets for testing.
Optionally, after obtaining the plurality of test packets, the method further includes: establishing a corresponding relation between the plurality of test data packets and the test cases; and storing the corresponding relation between the plurality of test data packets and the corresponding relation. The test data packet thus stored can be used directly for regression testing next time.
When the regression test is carried out, a test plan can be obtained, wherein the test plan comprises a plurality of test cases; acquiring SQL sentences in each test case in the plurality of test cases; acquiring a test data packet corresponding to the SQL statement of each test case, wherein the test data packet is obtained by replacing the SQL statement of the sample data packet with the SQL statement of each test case; sending the test data packet corresponding to each test case to an auditing program, wherein the auditing program is used for analyzing the test data packet and obtaining an SQL statement in the test data packet; acquiring an SQL statement obtained by analyzing the test data packet by the audit program, and comparing the SQL statement obtained by analyzing with the SQL statement in the test case; and the comparison result is used for determining whether the test case passes the test.
This is described below in connection with an alternative embodiment. In this optional embodiment, the data packet captured by the database client may be a data packet interacted with the database, and the captured data packet is stored as a sample packet.
And changing the packet based on the grabbed sample packet, replacing the statement, the session information and the result set information in the packet with the regenerated statement, session, result set and other information, and playing back to perform performance testing (for example, performing stress testing). The regenerated sentences can be generated by adopting a random algorithm, so that the diversity of data can be ensured. When modifying based on the sample packet captured now, for example, if the information such as the IP address or the port number, or the SQL statement is modified, the length of the modified packet may change, and if the length changes, the field in the packet for recording the length of the packet needs to be modified together.
The following describes specific steps of performing the performance test in this alternative embodiment.
Step 1, accessing a communication packet (referred to as a data packet for short) of the captured sample database, wherein the data packet can be divided into a data packet which is sent to the database by the database client and a data packet which is returned to the database client by the database. And storing the captured data packet (or simply called a communication packet).
And 2, analyzing the communication packet, acquiring key information to be modified, positioning the position and the length of the information to be modified in the communication packet, and recording.
And 3, generating information to be replaced according to the scene model to be simulated.
In this step, the information that may be replaced includes at least one of:
(1) and modifying the IP address, Port number (Port), MAC address and the like of the client and the server for simulating a high concurrency session scene. For example, a plurality of captured data packets may be used as one group, and then the group of data packets may be copied to obtain a plurality of groups of data packets, where IP addresses and port numbers of database clients related to each group of data packets are different, or IP addresses and port numbers of databases accessed to the groups of data packets are different, and then the plurality of groups of data packets may be sent to the auditing device, so that access between different clients and databases may be simulated, and a pressure test may be performed on an auditing program.
(2) The data packets are based on the TCP protocol, so the data packets carry the content of the TCP session, and each data packet in the TCP session has a sequence (sequence) and an acknowledgement (acknowledge) to the data packet with the sequence, so that the sequence and/or acknowledge values of the TCP session in the sample data packet can be modified to obtain a test data packet, and the test data packet is used for simulating scenarios such as retransmission, disorder, packet loss, and the like.
That is, when the test request indicates that the program requiring the audit processes the relevant content to the TCP packet sequentially, the sequence number and/or the acknowledgement of the TCP session in the sample packet may be modified to obtain the test packet.
(3) And modifying the session information of the database, such as a user name used for logging in the database, a client tool name used by the database, a user name of a database client operating system and the like, and using the modified session information to simulate scenes of various access modes and test the statistical aggregation performance of an auditing program (or called an auditing system).
When the request instruction tests the processing of the auditing program under various access scenes, acquiring different user names used for logging in the database, client tool names used by the database and user names of the database client operating system, and replacing corresponding data information in the sample data packet by the acquired user names used for logging in the database, the acquired client tool names used by the database and the acquired user names of the database client operating system to generate a test data packet.
(4) And modifying SQL statements carried in the data packet for testing the diversity of the audit program.
(5) And modifying the content of the result set, the line number of the result set and the length of the result set, and testing the processing performance of the auditing system when the large result set is returned. I.e. modify the result returned by the database SQL.
(6) Modifying the data packet sent to the database by the database client, so that the data packet is failed to be executed by the database, saving the data packet failed to be executed as a sample data packet, constructing various execution result error numbers and error information through the data packet failed to be executed, namely, respectively replacing the various execution result error numbers and the error information with corresponding data information in the sample data packet to obtain test data packets carrying the various execution result error numbers and the error information, wherein the test data packets are used for testing the statistical analysis capability of the auditing system on the failure request. And the data packet sent to the database by the database client can be modified, so that the modified data packet can simulate various abnormal attack accesses. By modifying the execution failure information, the influence of the execution failure of the database on the auditing system can be tested.
(7) The timestamp of the captured packet is modified to simulate a high response access. The captured data packet can be a data packet in a Pcap format, the Pcap packet can record a timestamp, so that the timestamp of the interval between a request packet and a response packet in the Pcap packet can be modified, a playback tool can play back according to the original speed, access of high response time is simulated, and the playback tool is used for testing the auditing and analyzing capabilities of an auditing program (or an auditing system) on high time-consuming requests.
Acquiring the time interval of the request and the response indicated in the request, acquiring a request packet and a response packet in a sample data packet, and modifying the time stamps in the request packet and the response packet according to the time interval to obtain a data packet for testing, wherein the time interval is obtained by subtracting the time stamp of the request packet from the time stamp of the packet after modification; and sending a request packet and a response packet which are used as the data packets for testing to the auditing program.
And 4, replacing the generated replacement information into the packet by using the position recorded in the step 2, and correcting the length information into newly generated data.
And 5, aiming at part of database protocols, recalculating a check value (checksum) value by using the modified packet, and updating the recalculated check value into the data packet to ensure the correctness of the communication packet.
Through the steps, multiple interactions can be simulated by replacing different contents each time by utilizing the interaction sample packet. When multiple interactions are simulated, a correct numerical value can be generated according to the sequence/acknowledge generation rule of the TCP, and the condition that the database auditing system considers an abnormal packet and does not process the abnormal packet is avoided. In addition, in the steps, a new communication packet generated can be replied by using packet playback tools such as TCPreplay and the like, so that the diversity of database audit performance tests can be achieved.
