The Basics of HTTPS
Have you ever observed that some URLs commence with “http://“, while others initiate with “https://“? The “s” indicates that the website is secure and uses Hypertext Transfer Protocol Secure. This protocol encrypts data transfer between browsers and servers, ensuring that your data is protected from eavesdroppers and Man-in-the-Middle (MitM) attacks.
So, what sets HTTPS apart from its unsecured counterpart, HTTP? The key difference lies in their data transmission; HTTPS encrypts the data being transmitted, whereas HTTP does not. Websites that require the transmission of sensitive information, such as credit card details or login credentials, particularly benefit from this encryption. In contrast, HTTP sites may not provide the same level of security.
However, no security measure is perfect, and HTTPS is no exception. While it does provide an additional layer of protection against DNS spoofing attacks, it’s worth noting that most web browsers don’t alert users when DNSSEC validation fails, which can limit its effectiveness. Despite this limitation, HTTPS continues to be a key element in the sphere of online security.
