Final answer:
Input validation is the protection that could be used to prevent an SQL injection attack. Input validation is the key method used to prevent SQL injection attacks. It checks user input against specific patterns to ensure its correctness before processing, thereby protecting the integrity of the database. The correct answer is B.
Step-by-step explanation:
The protection that could be used to prevent an SQL injection attack is input validation. Input validation involves examining the user input to ensure it meets certain criteria before it is used in a SQL query. This helps to prevent malicious statements from being executed.
For example, if a user is required to enter a username, input validation would check that the input does not contain any special characters or SQL keywords that could be used for an attack.
Input validation is the key method used to prevent SQL injection attacks. It checks user input against specific patterns to ensure its correctness before processing, thereby protecting the integrity of the database.
To prevent an SQL injection attack, the most effective method is input validation. This security measure involves checking user input against a predetermined pattern for correctness and integrity before it is processed by the application. Input validation helps to ensure that malicious actors cannot input SQL code into the database by exploiting input fields. This protection is vital for maintaining the security and integrity of the database. In contrast, buffer overflows, XML filtering, and lateral movement are not directly related to preventing SQL injections. Buffer overflows are related to controlling the amount of data written to a buffer, XML filtering is concerned with handling XML input and output, whereas lateral movement refers to the techniques used by attackers to move within a network.
