Question

Input Sanitisation and SQL injections question.

What is meant by the term ‘Input Sanitisation’ and how can it prevent SQL injections? Explain your answer in full.

Answer 1

Input sanitization refers to the process of ensuring that any data input by a user into a system or application is clean, safe and does not pose a security risk. This process is used to prevent malicious attacks such as SQL injection, which is a type of exploit that allows an attacker to insert malicious SQL statements into a web form input box to gain unauthorized access to a database.
