Introduction to SQLMap and SQL Injection Protection Techniques

SQLMap is an open-source penetration testing tool. It automates the detection and exploitation of SQL injection flaws, facilitating database takeovers and data retrieval.

SQL injection is a code injection technique used to attack data-driven applications. Malicious SQL statements are inserted into an entry field, compromising data integrity.

SQLMap supports various database servers, including MySQL, Oracle, PostgreSQL, and Microsoft SQL Server. It offers options for database fingerprinting, data fetching, and accessing the underlying file system.

Beyond mere data retrieval, SQLMap can enumerate users, passwords, privileges, databases, and even specific data subsets, giving attackers deep insights into the database structure.

SQLMap can perform database server takeovers using out-of-band channels or SQL injection vulnerabilities, providing unauthorized command execution and shell access.

Security systems can detect SQLMap through unusual database read/write patterns, timing anomalies, and signature-based IDS rules, enabling defensive countermeasures.

To protect against SQLMap and similar tools, developers must employ prepared statements, parameterized queries, stored procedures, and input validation.
