Before we talk about this, let's look at a piece of code: Copy Code code as follows: Dim sql_injdata,sql_inj,sql_get,sql_data,sql_post Sql_injdata = "' |and|exec|insert|select|delete|update|count|*|%| Chr|mid|master|truncate|char|declare " Sql_inj = Split (Sql_injdata, "|") If request.querystringFor each sql_get in Request.QueryString For Sql_data=0 to Ubound (Sql_inj) If InStr (Request.QueryString (Sql_get), Sql_inj (sql_data)) >0 Then Response.Write " " Response.End End If

has limited access to the database. If your application requires only read access, the access to the database is limited to read-only. Remove unused stored procedures from the production database. The access to the application is authorized only to the stored procedures created by the user. Do not authorize the application's "_any_" to the operating system commands or system stored procedures. What can the designer of an application do? Program designers shoulder the important responsibili

An article also said there would be a "third wave" of attack in the injection attack, it will be even more difficult to detect, even Microsoft's bosses have come out to clarify that Microsoft's technology and coding is irrelevant, Microsoft has launched a special three detection software, then this SQL injection

Objective: The goal of hacking is generally divided into two categories: one is to gain control of the system, remote monitoring or "command" your system, and the second is to steal your secret information, in the absence of completion of the target, hackers need "silent no Trace", the invasion of the secret, can not let the support found. Intrusion is not the same as attack, and intrusion is often the prophase work of

One, what is SQL injection-type attack? An SQL injection attack is a query string that an attacker inserts a SQL command into a Web form's input field or page request, tricking the server into executing a malicious SQL command. In some forms, user-entered content is used directly to construct (or affect) dynamic SQL c

1. Escape characters are not filtered correctly This form of injection or attack occurs when the user's input does not escape character filtering, which is passed to an SQL statement. This causes the end user of the application to perform operations on the statements on the database. For example, the following line of code demonstrates this vulnerability: The code is as follows Copy Code

SQL injection is a very familiar way to attack, and there are a large number of DBMS (such as mysql,oracle,mssql, etc.) on the network that are injecting vulnerabilities. However, I can't find any resources on the network for the Hibernate query language. Therefore, this paper summarizes the author's experience and skills in the process of reading documents and constantly experimenting.What is HibernateHibe

SQL injection attacks are the most common means by which hackers attack websites. If your site does not use strict user input validation, it is often vulnerable to SQL injection attacks. SQL injection attacks are typically implemented by submitting bad data or query statements to the site database, which is likely to e

First, Introduction PHP is a powerful but fairly easy-to-learn server-side scripting language that even inexperienced programmers can use to create complex, dynamic Web sites. However, it often has many difficulties in achieving the secrecy and security of Internet services. In this series of articles, we'll show readers the security background and PHP-specific knowledge and code necessary for Web development-you can protect the security and consistency of your own Web applications.
