Hey everyone this is saga from up degree and in this lecture I want to talk about how any of the application
works or how any mechanism works.
Well there is always a four step process that we are going to talk about today.
See the user is the Internet right.
User is connected to the Internet and he is going to send some request from Internet Internet.
Submit that request to the voiceover of the application.
For example if I have developed sites saga Benson dot com.
The Internet is going to send a request to the video server of my web site.
The observer will then determine what it has to do with the request it will forward the request to the
file server or the database.
So you're right.
Generally it happens in the series.
That process the request to do file server the file server will give it all the files.
For example there is a page which is like index dot HD.
The file server will give that page to the web server and most of the web application they store their
data in the database.
So this Web server will extract the data from the database and put all of these things together and
give it back to the Internet as a response.
So these three servers are important right now with these two servers.
There is always a need of process processor.
In this case I took the example of HP processor but they can meet different kinds as well.
For example there may be in North DSL application there you will need in naughtiest processor.
There can be angular application you will need a angular processor so it will depend what processor
do is that it processed the files and the database queries and it allow you to process all the works
in the web server.
Now there is the vulnerability in this one provided ability can lie in all these stages.
The request coming from internet to web server or the response going from web server to Internet the
request from observer to files over the request from web server to database the request in between of
the processing with the processor the vulnerability can be anywhere and all of these things makes the
basic element of that penetration testing.
This is what we have to do.
We have to find weaknesses between all these four elements.
Right.
That's what is our job.
This is how a website or a web application works.
I'll keep the series going in the next lecture till then.
Have a great day.
