Why do we need secure data moving over the internet
When data normally moves access the internet we tend to think of it as going from point A (us) to point B ( the server website or service )
We all know that when visiting a website you want HTTPs instead of HTTP and that the S means it's secure which intern tells us that any data that moves between you and the server is encrypted.
Which is Fantastic…
The thing to remember is that between you and the server's that run the website your looking at can be anything, including other server's and other people.
If that data isn't encrypted then those people can see everything
- Where your going.. i.e. the website.
- Who and where you are.
- Your password, credentials, everything the browsers send back and forth.
This is why HTTPS is such an important thing, It stops our man in the middle from seeing that data - all he sees is what looks like random information.
Of course, that's not the whole story, there are many other forms of attack and privacy concerns about who can see where what your doing.
