if you are a web database software developer using PHP language, list and explain different methods/implementation that you can help to protect database and improve the database security?

Solution

by using authentication mechanisms

we can secure database by giving username and password.This user name and password can be saved in the server.this logic can be coded in php everytime when we login to a database in a server,it will ask for user name and password.if both are valid,then we can login to database,otherwise it will not allow us to login . note that php is a server side scripting languages.

we can also secure secret data by making those data avalaible only to authorised members ,so others cannot modify or harm data deliberately or accidently.

if passwords are forgotten,then we can make use of secret question and solutions which will be known by only the user fed to the server.
