Encryption of data while transferring it over the internet goes a long way in keeping your information secure on the internet. Using HTTPS Encryption while surfing helps in securing your data when you are using a public Wi-Fi network and gives added protection if you are surfing in a secure network.
If you are wondering what the HTTPS protocol means and why everyone says it’s so important to use whenever possible – you have come to the right place.
If you don’t not want anyone to read any sensitive information like your banking data or EMail Inbox, you may want to use HTTPS every time possible. Lets look how HTTPS works and keeps your data secure.
What is The HTTPS And How Does It Secure Your Data?
Normally when we surf the internet, we use the HTTP (hyper text transfer protocol) – which is the system that facilitates data transfer and reception over the internet. In many ways, HTTPS is identical to HTTP, because it follows the same basic protocols. The HTTP or HTTPS client, such as your browser, establishes a connection to a server on a standard port.
HTTP is insecure and is subject to man-in-the-middle and eavesdropping attacks which can let attackers gain access to website accounts and sensitive information. HTTPS is designed to withstand such attacks and is considered secure against such attacks.
There are some differences between HTTP and HTTPS, first one being the default port used. HTTP uses the port 80 where as HTTPS uses port 443. HTTPS works by transmitting normal HTTP interactions through an encrypted system, so that the information cannot be accessed by any party other than the user and end server.
In case you are accessing sensitive sites like your banking account or email – many websites offer the HTTPS connection to make sure no one can eavesdrop on your data. For eg – The banking and email sites below offer you secure data transfer.
Many browser, like Firefox in the screenshot above (banking site) and below (email site) display the encryption status of any website in the address bar.
The HTTPS security protocol operates at a lower sublayer of data transmission, encrypting an HTTP message prior to transmission and decrypting a message upon arrival.
When should we use HTTPS while surfing?
HTTPS is used at many locations like the log-in pages for banking, forms, corporate log-in pages and other applications like the Email – in which data needs to be secure. However, if not implemented properly, HTTPS is vulnerable to security breach.
Thus it is extremely important for end users to be wary about accepting questionable certificates and cautious with their personal information while using the Internet.
Realizing the importance of keeping your searches private – Google Search has implemented a secure version of its search engine – which can be accessed by going to “https://www.google.com”.
Anytime you are accessing a Secure website – you may want to make sure that the certificate is signed by a trusted authority. A detailed and informative post about how to validate certificates would be written soon for our readers to understand how to verify the validity of an SSL certificate.
