How do I prevent cross-site request forgery (CSRF) attacks in Yii?
Yii The key to preventing CSRF attacks is to use the built-in mechanism correctly. First, Yii enables CSRF protection by default and generates tokens automatically. Tokens will be added automatically when using ActiveForm or Html::beginForm; second, when writing forms manually or using AJAX, you need to obtain the token through Yii::$app->request->csrfToken, and it is recommended to pass it to JS through meta tags; third, for the API interface, you can choose to turn off CSRF and strengthen other authentications such as JWT, or pass tokens through header; finally, sensitive operations should be avoided in GET requests, and only use POST/PUT/

What is the purpose of Gii in Yii?
Gii is a powerful code generation tool in the Yii framework, which accelerates the development process by generating boilerplate code based on database structure or input parameters. Specifically, Gii can generate ActiveRecord models, create controllers containing CRUD operations, build corresponding views, and help build components such as modules and forms. To enable Gii, add 'gii' to the 'bootstrap' array in the configuration file config/web.php, and configure its class and access restricted IP in the 'modules' section. Gii helps keep code consistency and conforms to Yii best practices and is suitable for quickly building data-intensive applications such as CMS or management panels. Although the generated code is a skeleton,

What are best practices for securing a Yii application?
Ensuring the security of Yii applications requires starting from five aspects: input verification, authentication and authorization, database security, error handling and configuration management. 1. Input verification should use model rules to filter user input, such as required, email, string validators, and combine HtmlPurifier to prevent XSS attacks; 2. In terms of authentication, Yii's RBAC management permissions should be used to restrict access roles through AccessControl; 3. Database operations should rely on parameterized queries to prevent SQL injection and avoid hard-coded database credentials; 4. Error handling requires closing debug mode, setting custom error pages and recording logs; 5. Configuration management should regularly update the framework and dependency library to fix vulnerabilities

What are controllers in Yii, and what is their purpose?
In Yii, the controller coordinates application logic by processing user requests, interactive models, and rendering views. The main responsibilities of the controller include: ① Processing HTTP requests; ② Interacting with the model to obtain or save data; ③ Deciding which view to display and pass data; ④ Processing form submissions; ⑤ Returning HTML, JSON or redirection responses. Yii controllers are usually inherited from yii\web\Controller, and each public method corresponds to an action that can be accessed through the URL. For example, visiting http://example.com/site/index will call the actionIndex() method of SiteController. Common tasks include verification of input, calling models, and rendering

How do I log security events in Yii?
Recording security events in Yii can be achieved by configuring log targets, triggering key event logs, considering database storage, and avoiding recording sensitive information. The specific steps are as follows: 1. Set a dedicated log target in the configuration file, such as FileTarget or DbTarget, and specify the classification as 'security'; 2. Use Yii::info() or Yii::warning() to record the log when a critical security event (such as login failure and password reset) occurs; 3. Optionally store the logs in the database for query and analysis, and you need to create a table first and configure the logTable parameters; 4. Avoid including sensitive data, such as passwords or tokens when recording context information, and you can use parameter replacement to add IP and username; 5
