Let us acknowledge the definition of SQL injection attacks before indulging into the matter. Well, the SQL injection attack can be defined as the code injection technique, which is used to attack the applications that are driven by data. With the help of SQL injection attacks, the attackers establish numerous cyber destructions like spoofing of the identity, causing repudiation, destroying data and numerous other things. Thus, it is very important for us to protect ourselves from the SQL injection attacks, if we want to ensure the protection of our data. Here are some tips to help you:
Make use of prepared statements to protect from SQL injection Attacks
Let us acknowledge the definition of SQL injection attacks before indulging into the matter. Well, the SQL injection attack can be defined as the code injection technique, which is used to attack the applications that are driven by data. With the help of SQL injection attack, the attackers establish numerous cyber destructions like spoofing of the identity, causing repudiation, destroying data and numerous other things. Thus, it is very important for us to protect ourselves from the SQL injection attack, if we want to ensure the protection of our data. Here are some tips to help you:
Make use of prepared statements
Using prepared statements is considered to be one of the finest ways to protect ourselves from the SQL injection attacks. Also, compared to the dynamic SQL series, it is pretty easy to understand. This is the time, when the SQL command utilizes the parameters rather than the direct insertion of the values in the command. By doing this, it is preventing the backend to go through the malevolent queries, which are severely harmful for the database. Thus, if the user is entering 12345 or 1=1 as its input, parameterized query will search the entire string 12345 or 1=1.
Stored procedures can be utilized as well to protect from SQL injection attacks
In addition to using the prepared statements, if you use a stored procedure, it will provide you with an extra layer of security. It will perform the essential escaping, which is required, thus the app treats the input to be functioned instead of the SQL code, which was about to executed. Well, the basic difference between the stored procedures and the prepared statements is that, in case of stored procedure, SQL is code is written and also, stored in database of the server and after that, it is called from the web app.
Validating the input of the user
Another way of fighting the SQL injection attacks is to validate the user input. Even if you are utilizing a prepared statement, make sure to validate an input at first to determine that the value is one of the accepted types, format, length or any other things. The input that can pass the validation can only be allowed to process towards the database. So, this is one of the methods to protect you from the SQL injection attack. You can consider this method as asking who is on the door before opening the door.
Limit the privileges
Limiting the privileges can be the other way of protecting one from the SQL injection attack. Well, it is recommended that do not connect to your database with an account that has root access. Well, emergency is the exceptional case. If you use an account that has the root access, there are numerous chances of SQL injection attacks. Thus, use an account that has limited privileges.
So, these are some of the tips, which you can use if you want to protect your data from SQL injection attacks.
