Explain how the data is secured in HTTPS?

HTTP secure or HTTPS can be thought of as an extended version of the regular HTTP. This communication protocol is the widely used one next to the regular HTTP when it comes to having a secure communication path between the user and the server over a computer network. 

The HTTPS finds quite a wide deployment over the internet when compared to deployment over intranet. If we understand it deeply we will come to know that in actual it is not a protocol in itself as it seems so from outside. 

It is actually a regular hyper text transfer protocol (HTTP) simply layered over SSL/ TSL protocol. The SSL/ TSL protocol thus lends its security capabilities to the standard HTTP communications when HTTP is layered up on SSL/ TSL. 

In this article we discuss how the data is secured in HTTPS. As we mentioned above that it is quite deployed in the internet services and it is so because it provides a quite convenient means to authenticate the web site as well as the web server associated with it (with which the connection is being established).

How data is secured in HTTPS

Such an authentication is of much importance as it provides the protection against the man in middle attacks which usually occurs because of eavesdropping between our communications with the server. 

- Moreover, HTTPS provides bidirectional encryption of the communications or the data that is exchanged between the clients and the servers. 

- The ability of the bidirectional encryption by virtue of which it protects against tampering and eavesdropping which otherwise would forge the contents of the communications between the clients and the servers, makes it much necessary. 

- HTTPS comes with a reasonable guarantee that you get to communicate only with the web site which you intended to communicate with and with none else.  - Furthermore, a way to prevent the forgery of the contents of the communication that takes place between the users and the clients cannot be hampered or forged by any of the third parties is ensured by the http secure. 

- In HTTPS, the entire HTTP is levied up on the top of the TSL or SSL thus enabling the total encryption of the HTTP communications content.

- This communications content includes:

1. Request URL which states the particular web page that was requested.
2. Query parameters
3. Headers
4. Cookies containing the identity information about the user and so on. 

Negative Points of HTTPS

Though the HTTPS has got many advantages, its minus point cannot be unseen.

-HTTPS cannot protect the disclosure of the communication content.

-This happens so because the addresses of the host web sites and port numbers form a necessary part of the TCP/ IP protocols that underlie the https. -To be seen practically, it means that the identity of the server can still be inferred by the eavesdroppers even on a correctly configured web server as well as the amount and duration of the communication.

-In the early years, the HTTPS was common to be used in the money transactions over the World Wide Web and other sensitive transitions like e- mails.

-In the recent years it has been known for the following:

1. Authenticating the web pages,
2. Providing security to the accounts,
3. Maintaining the privacy of the user communications, web browsing and identity.

The HTTPS has also come to the rescue of the wi- fi since it is highly prone to attacks being un- encrypted. The importance of https is often more realized when the connections are made over tor or anonymity network.
