Which attack exploits the security vulnerability of a database for attacks, injecting malicious code into strings that are later executed by the SQL server?

• A. SQL Injection Attacks
• B. Command Injection Attacks
• C. Web Defacement
• D. Web Cache Poisoning Attack

Answer: (A)

SQL injection is a vulnerability where user input is directly included in a database query without proper validation or parameterization. When input is concatenated into the SQL statement, an attacker can insert malicious SQL code that the database server then executes. This allows actions like bypassing authentication, extracting data, or modifying or deleting records. In the described scenario, the attacker’s malicious code is embedded in strings sent to the database and executed by the SQL engine, which is the hallmark of an SQL injection attack. The other options describe different threats: command injection targets the server’s operating system commands, web defacement is about altering webpage content, and web cache poisoning corrupts cached resources. The key distinction is that only SQL injection directly exploits the database by injecting code that the SQL server executes. Preventive measures include using parameterized queries or prepared statements, rigorous input validation, least-privilege database accounts, and stored procedures with proper parameter handling.
