6. Security system in detail
SQL injection
How does hackers inject bad thing lets have an
example.
The most common thing the hacker do first is bypassing
how dose it works ?
Lets have a look on our sql query for a login system
$query="select username,pass from users where
username='$uname' and password='$passwrd' limit 0,1";

7. Security system Continued
Hackers generally perform bypassing like this
Username : ' or ''='
Password : ' or ''=‘
Then the query looks like
select username, pass from users where username='' or
''='' and password='' or ''='' limit 0,1;
To get ride of this we took 2 steps
First one is to validate the form so that user could not enter
any special character.
Then we used PDO
Which contains prepare function to execute query.
