Second-order SQL injection occurs when an application only guards its SQL against immediate user input, but has a less strict policy when dealing with data already stored in the system. Therefore, although such application would manage to safely process the user input and store it without issue, it would store the malicious SQL statement as well.
Encoding input or escaping dangerous characters. For instance, in PHP, using the htmlspecialchars() function to escape special characters for safe output of text in HTML and the mysqli::real_escape_string() function to isolate data which will be included in an SQL request can protect against SQL injection.
Major Companies Impacted by Data Breaches. Cybersecurity Awareness Month brings the financial impact of data breaches into sharp focus. In 2024, the average cost of a data breach soared to $4.88 ...
A web application firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web service.By inspecting HTTP traffic, it can prevent attacks exploiting a web application's known vulnerabilities, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration.

Some protection from SQL injection attacks Stored procedures can be used to protect against injection attacks. Stored procedure parameters will be treated as data even if an attacker inserts SQL commands. Also, some DBMS will check the parameter's type.
One technique for evaluating database security involves performing vulnerability assessments or penetration tests against the database. Testers attempt to find security vulnerabilities that could be used to defeat or bypass security controls, break into the database, compromise the system etc. Database administrators or information security administrators may for example use automated ...
Cyberattack Protection: SQL injection is a type of attack used to exploit bad coding practices in applications that use relational databases. The attacker uses the application to send a SQL statement that is composed from an application statement concatenated with an additional statement that the attacker introduces.
Defensive programming is a form of defensive design intended to develop programs that are capable of detecting potential security abnormalities and make predetermined responses. [1]
