in the username input box on the logon page: '; Show tables; Click the login key. This page displays all tables in the database. If he uses the following command: '; Drop table [table name]; In this way, a table is deleted! Of course, this is just a simple example. the actual SQL injection method is much more complicated than this one. hackers are willing to spend a lot of time trying to attack your code. Some program software can also automatically attempt SQL injection

attacks are another way to launch an attack, but they are a slightly different approach. When performing a standard SQL injection attack, an attacker inserts an SQL query into a Web application, expecting the server to return an error message. This error message enables an attacker to obtain the information needed to perform a more precise attack. This causes the database administrator to believe that a message that eliminates this error will resolve

Code used to prevent SQL injection attacks. SQL injection attacks use designed vulnerabilities to run SQL commands on the target server and perform other attacks, when SQL commands are dynamically generated, the number of SQL injection attacks that are not input to users are

Many network administrators encounter malicious website attacks when managing internal networks and preventing viruses. Many employees' computers often access malicious websites automatically due to the accidental installation of rogue software, as a result, the virus can spread in a wide range. In the past, we used to edit the HOSTS file of the employee's computer to point the illegal site to the 127.0.0.1 address and filter it out. However, this met

How to Prevent SQL injection attacks and SQL Injection 1.

With the simplification and foolproof nature of hacking tools, a large number of low-tech users can also use hacking tools in their hands to launch attacks (these people are also known as "gray customers "), our internet security has been greatly threatened. Can we be forced to beat them? Of course not. As long as the settings are well set, these people cannot help us! Please refer to the ten methods described in this article. 1. Hide IP addresses Hac

troublesome thing for me is session spoofing (or csrf, you can refer to it as you like), because this attack is completely based on the user identity, therefore, there is no possibility to prevent it. If you don't know much about the session spoofing I just mentioned, you can read: http://www.playhack.net/view.php? Id = 303. Feasible Measures OK. From here on, I must assume that you have thoroughly understood the implementation method of session s
