A secure connection is a connection that is encrypted by one or more security protocols to ensure the security of data flowing between two or more nodes. When a connection is not encrypted, it can be easily listened to by anyone with the knowledge on how to do it, or even prone to threats by malicious software and rogue and unexpected events.
Anyone who wants to get information from a non-secured connection can do so since they can easily go through, in and out of the computer’s network taking with them important data such as login, passwords and other private information.
Secure connections, as they supposed to protect the data being transferred from one computer to another, must be able to do three main things.
- Prevent third parties from getting hold of confidential data
- It must first validate the identification of the person who wishes to access and exchange the data
- It must protect information from being viewed or altered by unknown parties
There are many methods to be able to establish a secure connection, but most of them involve data encryption. Data encryption is a method which hides information from other unauthorized parties. This method usually needs an appropriate program installed on both computers involved in the connection that will encrypt and decrypt the information. Among these are our basic security protocols embedded in main communication protocols like TCP/IP, HTTPS, POP3 or IMAP.
