Example 1:
the embodiment provides a web application protection method, as shown in fig. 1, applied to a system including a front end and a back end, where the method includes:
step S102: the front end sends a data request to the back end, where the data request carries a URL (Uniform Resource Locator) and parameter information.
In this embodiment, the front end is a part that can be seen and interacted with by a user in a Web application, and includes a structure of a Web page, an appearance visual representation of a Web, an interaction implementation at a Web level, and the like, and the back end processes a corresponding service logic by interacting with a database, and mainly includes: implementation of functions, storage and access of data, and the like. When a user accesses a Web application page, inputting parameter values in an input box corresponding to the page, then clicking a corresponding submission button to execute a request operation, at this time, sending a data request to a back end by a front end, wherein the data request carries a URL (uniform resource locator) and parameter information required by the request, and the parameter information specifically comprises a parameter name and a parameter value.
Step S104: and after receiving the data request, the rear end analyzes the parameter information to obtain a corresponding parameter value.
In this embodiment, after receiving the data request, the backend analyzes the parameter information, and obtains a corresponding parameter value from an analysis result.
Step S106: and the back end generates a corresponding parameter picture according to the parameter value and stores the parameter picture in a preset database.
In the embodiment, in order to prevent an attacker from attacking through a carefully constructed parameter value, the back end generates a corresponding parameter picture according to the parameter value, and stores the parameter picture in a preset database, so that a good protection effect on the web application can be achieved. Taking a scene of a message or comment of a user as an example, the scene of the message or comment area of the user is often encountered in the internet surfing, the normal process is that the user submits the comment content (namely a parameter value) in the comment area after the comment area is commented, the back end stores the comment content in the database, and when the page is accessed again, the back end takes the comment content out of the database and sends the comment content to the front end, and the comment content is displayed back on the page by the front end. At this time, if an attacker writes a malicious script in the comment content, the browser executes the malicious script in the page playback process, and since the comment content is visible to all users, each user executes the malicious code when accessing the comment, which causes a wide-range attack, which is a typical XSS attack scenario. However, when the comment content is converted into the picture through the method and the device, no matter what comment content is input in the comment area, the browser cannot execute the malicious script, and therefore the safety of the web application is guaranteed.
Optionally, the generating, by the back end, a corresponding parameter picture according to the parameter value may specifically include:
the back end judges whether the parameter value needs to be rendered;
if so, the back end acquires a rendering style corresponding to the parameter value, and performs rendering according to the rendering style to generate the parameter picture;
and if not, the back end generates the parameter picture according to a preset default style.
In this embodiment, in order to enhance the aesthetic property of the page, a corresponding parameter picture may be generated according to a style to be displayed at the front end, and the parameter picture may be a dynamic picture or a static picture, so that when a parameter value needs to be displayed back on the page, the parameter picture obtained after rendering processing is displayed to the user, and the visual experience of the user is improved. Specifically, the back end first determines whether the parameter value needs to be rendered, specifically, whether the parameter value needs to be rendered may be determined according to a parameter name or whether the parameter value has an associated rendering style, if the back end determines that the parameter value needs to be rendered, the back end may first obtain a rendering style corresponding to the parameter value, the rendering style may be written into a document by a front-end designer in advance, and then the back end performs rendering according to the rendering style in the document, thereby generating a corresponding parameter picture, where the rendering style may be, for example, a bold font, a red color, and the like. If the back end judges that the parameter value does not need to be rendered, the back end generates the parameter picture according to a preset default style, for example, the parameter picture generated by the default style can be a picture of black characters with white background.
Optionally, after the back end generates a corresponding parameter picture according to the parameter value, the method may further include:
the back end judges whether the parameter value contains sensitive data;
if so, adding a fixed salt value in the parameter picture by the rear end;
the storing the parameter picture in a preset database may specifically include:
and storing the parameter picture added with the fixed salt value into the preset database.
In this embodiment, in order to ensure the security of the data and facilitate the subsequent operation of removing the salt value, a fixed salt value may be added to the parameter picture corresponding to the parameter value containing the sensitive data. Specifically, the back end first determines whether the parameter value includes sensitive data, and specifically may determine according to a keyword or a parameter name, for example, if the parameter value includes keywords such as a password and an identity card number, it determines that the parameter value includes sensitive data and needs to be encrypted, and at this time, the back end adds a fixed salt value to the parameter picture and stores the fixed salt value in the database.
In this embodiment, when the parameter value needs to be displayed, the front end sends a parameter display request to the back end, the back end sends the parameter picture to the front end according to the parameter display request, and the front end receives the parameter picture and then displays the parameter picture at a predetermined position. If the parameter picture is the parameter picture added with the fixed salt value, the back end firstly carries out salt value removal processing to restore the parameter picture before the fixed salt value is not added, and then sends the picture to the front end.
In this embodiment, the parameter picture generated by the default style may specifically be a grayscale picture, the parameter picture generated by the rendering style may specifically be a color picture, the parameter picture generated by the style may specifically be stored in a preset database in a matrix form, for example, the grayscale picture, and if the corresponding parameter value is a number 1, the corresponding matrix may be as follows:
Figure BDA0003316382950000071
wherein, the row of the matrix corresponds to the height (unit is pixel) of the parameter image, the column of the matrix corresponds to the width (unit is pixel) of the parameter image, the element of the matrix corresponds to the pixel of the parameter image, and the value of the element of the matrix is the gray value of the pixel.
In this embodiment, if a field corresponding to the parameter value in the database is set as a primary key, for example, the parameter value is a user name (admin), the back end stores a picture generated by the user name in the database, the parameter picture is used as a key value picture and is stored in a matrix form, at this time, if the front end wants to query the user admin, the front end sends the admin to the back end, the back end converts the parameter value admin into a corresponding parameter picture, the parameter picture is converted into a picture matrix by an OpenCV or other picture processing plug-in, then all key value pictures in the database are traversed, and information corresponding to the admin can be queried by comparing corresponding matrix values.
According to the web application protection method provided by the embodiment of the invention, firstly, a data request is sent from a front end to a back end, the data request carries URL (uniform resource locator) and parameter information, then the back end analyzes the parameter information according to the received data request to obtain a corresponding parameter value, finally, the back end generates a corresponding parameter picture according to the parameter value, and the parameter picture is stored in a preset database. According to the invention, by imaging the parameter values, the web application risk caused by inserting malicious codes into the parameters can be avoided, cross-site scripts, sql injection, file uploading, brute force cracking and other attacks can be effectively prevented, the safety of the web application is improved, the comprehensive protection on the web application is realized, and the problem that the web application is not completely protected by the existing web application protection method is solved.
