One of the questions that is most
important to web development but often not given adequate attention
is how the platform or language that you are using to build your
website with helps you secure your data. This question becomes all
the more important in the present scenario where we have threats to
private data from all quarters. In this article, we look at how PHP
helps you secure your data.
Data Validation
This is the
first thing that should be focused on while trying to secure web apps
with PHP web development.
The first thing that should be done is to
filter and validate the incoming data as that will prevent a hacker
from entering any bad input. The data should
be validated in the PHP code. This is one of the sheer advantages of
using a PHP web development over Java because users can always turn
off the javascript in their browser and prevent an app from
validating an input. So, the first kickass way of securing a web app
is to hire PHP developers.
Protecting Session Data
A session
information gets automatically written on a tem directory. When it
comes to a shared hosting server, anyone with whom it is shared can
write the script and also read the session data quite easily. Hence,
it is advised that one should not retain sensitive data such as
credit card information and passwords in the session. An easy way of
safeguarding the data is to adhere to encryption. However, that too
isn't a completely secured way.
Guarding Included Files
A lot of
PHP files are often included in PHP scripts. These scripts contain
things such as code for connecting to a database. In some cases it
has been found that some developers include .inc extension. However,
files with such extensions are not analyzed by PHP. This can be a
safety issue as hackers might get an easy access to the data in the
app. The safest thing to do is to use the .PHP extension.
