attacks. Some rules are simple and extreme, and a potential attack will be vigilant. However, these extreme rules can lead to some active errors. With this in mind, we have modified these simple rules and used other styles to make them more accurate. In the attack detection of these network applications, we recommend that you use these as the starting point for debugging your IDS or log analysis methods. After several modifications, you should be able to detect the attacks after evaluating the

Web applications generally use form-based authentication (as shown in Figure). The processing logic is to pass the user name and password submitted in the form to the background database for query, determine whether the authentication is successful Based on the query results. For web applications with LAMP architecture, PHP is used for processing logic, and MySQL is used for background databases. In this process, due to poor processing, many serious vulnerabilities may occur. Apart from weak pas
