What is SQL Injection?
SQL injection is a method of exploiting an application’s use of Structured Query Language (SQL) to alter, delete, or insert data into the database. SQL Injection attacks can be conducted without a hacker having direct access to the database. An attacker may exploit a web application vulnerability to inject SQL statements by using the following methods: Injection through user input such as in a search box, email address field, or URL parameter Injection through web server configuration settings such as default credentials and default database name.
Types of SQL Injection
SQL injection is a type of injection which is used in the SQL language. It’s an attack technique that allows hackers to exploit vulnerabilities in the application by injecting SQL statements into the query. SQL injection flaws can be found in any database management system, whether it’s a relational database management system (RDBMS) or a NoSQL database management system (NoSQL). SQL injection attacks are common because most applications that use databases rely heavily on user input to populate tables and queries.
SQL Injection Attack Consequences
SQL Injection is a vulnerability that occurs when a user enters malicious SQL commands in order to manipulate the database. SQL is a powerful language, and it can be used to do anything from selecting information from the database to changing it. This can be done by tricking the application into thinking that the user is entering data when they are not. The repercussions of an SQL injection attack can range from minor annoyances to major security breaches. The most common result of an attacker accessing your website’s database is getting unauthorized access to your site. You may think that your website has been compromised, but it actually just means that someone else has been able to access your account with your username and password.
If this happens often enough, you’ll eventually get locked out of your account completely and lose access to all of your information stored in the database. This can be very dangerous if you have sensitive information such as financial information or credit card numbers stored there. Another major consequence of an SQL injection attack is losing control over how much money you’re making at the end of each month or quarter based on how much revenue you make through ads on your website (if any).
How to Prevent SQL Injection Attacks?
SQL injection attacks can be prevented by using a tool like OWASP SQL Injection Prevention Cheat Sheet that will help you find these common vulnerabilities before they happen.
How to Protect Your Database from SQL Injection Attacks?
To protect your database from SQL injection attacks, you should implement the following:
Preventing Code Injection: Using parameterized queries where possible, or if not possible, using prepared statements. This allows for greater security because it prevents unknown values being passed into the query or inserted into the table. Disallowing White-Listing of User Inputs: By default, MySQL does not allow for user input parameters to be submitted with invalid characters or syntax errors such as quotes, parentheses or spaces. This makes it more difficult for hackers to exploit your database through these methods.
