Explanation:
By validating user input and preventing special characters, we can prevent the injection of client-side
scripting code.
SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL
statements are inserted into an entry field for execution (e.g. to dump the database contents to the
attacker). SQL injection must exploit a security vulnerability in an application's software, for example, when
user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or
user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack
vector for websites but can be used to attack any type of SQL database.
