The title "Do you leave your Digital Fingerprint?? What if i say you do!! Yes, you may be one among the 99% people without your knowledge!" itself explains the content we're gonna see in this post. Yes, about digital footprinting, Browser hardening and so on..
Its been so long, since i wrote a post in this year. Thanks to the pandemic.:(
After so long, why this post especially??
I decided to write this post, as more number of our family/readers started falling as victims for the online Surveillance, malware's, Ransomware, and much more, which even we don't know that exists.!
So, its a kind of informational post and if you are worried a lot about your privacy, then by following this post, you can save yourself from leaving your fingerprints or footprints as much as possible whenever possible.
Okay, before we get in, let me explain some terms in short, so that our beginner's or people new to Sec can understand.
What is digital footprint or What is digital fingerprint?
"Every information you leave on internet about you can be traced back to you!!"
Yes, you are leaving more information about you, than you actually know.. Let me say a couple of information/examples..
You are visiting one website let's take famous website like google or even our site. So, whenever you visit this sites, an information about your device you used will be communicated to the web servers. For example: What device you are using, what is your IP address, what is your Mac address, your location, your language,etc thingss..
You may say, this is how internet works, or this is necessary for internet to work, of course it is essential for the internet to work, but that's not what's happening here..
Some sites even collect more information than this like what do you like, what you don't like, what is your upcoming plan,etc.. things.!
This information is being misused by lot of companies, especially by advertising agencies to serve you the ads that are required, forcing you to buy the things that you are interested and not interested. Does it limits to advertising alone?? Obviously, No!! Its more than that..
Imagine this scenario, you had planned to travel this week to some abc place, this information as some sites like social networking sites already know, they will share the info to advertisers (based on algorithms) and will provide releavant ads like booking a taxi,etc..
What if it falls into wrong hands?? They can even put a big sketch to finish you without any trouble, which is the sad truth..
So, is there anyway we can prevent this, yes there are multiple ways like using VPN/tor,etc.. which i had covered in 2020 itself through this post.
But, there is one important concept called Browser hardening, which we will see in this post.
What is Browser Hardening?
Where can i do browser hardening or how to do browser hardening..?
