A SQL injection (SQLi) attack is one of the most threatening issues for data integrity and confidentiality today, allowing attackers to access secure data where they are not authorized. In this article, we discuss SQLi and how these attacks work, with types and examples. By Al Mahmud Al Mamun.
SQL injection or insertion is a malicious attack technique that exploits vulnerabilities of SQL-based applications. With SQLi, hackers inject arbitrary code into SQL queries, which allows them to directly add, modify, and delete records stored in a database. SQLi attacks can affect any web application or website involved with a SQL database, such as MySQL, SQL Server, Oracle, and others.
The article describes:
- What is a SQL injection?
- How does a SQL injection attack work?
- Examples of SQL injection attacks
- Types of SQL injections
Every organization needs to focus on protecting its valuable information from SQLi attacks. There are many automatic detection tools available to test for these vulnerabilities. A layered approach that includes data-centric strategies can be the optimal defense for SQLi attacks, where data focuses on protecting itself, as well as the applications and network. Good read!
