What is HTTPS and Why Is It Important?

Have you ever thought about why it is essential to communicate securely with websites? HTTPS is one of the cornerstones of protecting this communication.

In the face of ever-increasing cyber threats, it has become imperative to ensure the confidentiality and integrity of data. HTTPS is one of the indispensable elements of internet security, making it possible for users to surf safely.

Basics of HTTPS

HTTPS stands for Hyper Text Transfer Protocol Secure and enhances security by encrypting data sent over the internet. It is based on SSL/TLS protocols, which guarantee that data transmission is confidential and unalterable. Communication between the user and the server is thus protected, preventing intermediate points from reading or manipulating the data.

In Internet security, HTTPS connectivity has become an almost mandatory requirement for secure data exchange. Especially for e-commerce sites, banking services and other platforms that handle sensitive data, HTTPS plays a key role in protecting users’ information. At the same time, it supports the credibility of websites and users’ privacy rights, making HTTPS not only a security protocol, but also an important element in digital reputation management.

Difference between HTTP and HTTPS

HTTP (Hyper Text Transfer Protocol) is a basic protocol that regulates communication between web servers and users and does not encrypt data during data transfer. This allows data to be easily readable by third parties.

HTTPS (Hyper Text Transfer Protocol Secure) is a secure version of HTTP and protects the confidentiality and integrity of transmitted data using SSL/TLS encryption protocols. This encryption protects against attempts to intercept, eavesdrop or modify data.

HTTPS supports the freedom of the internet by preventing censorship or content manipulation.

In an epilogue: HTTPS is the first line of defense against data theft, phishing attacks and other cyber threats. The use of HTTPS in the transfer of all kinds of personal data is considered and recommended as the cornerstone of a reputable and reliable Internet environment.

Working Principle of HTTPS

HTTPS adopts SSL/TLS encryption protocols to ensure a secure communication setup between the user and the server.

• Encrypted Connection: An encryption key is exchanged between client and server.
• Certificate Verification: The trustworthiness of the server is confirmed by a digital certificate issued by a certification authority (CA).
• Data Integrity: The data sent is encrypted and integrated to protect against manipulation.

These processes guarantee the confidentiality and integrity of the information sent by users.

It acts as a barrier against interference or data eavesdropping attempts and protects user data.

Security Advantages

The use of the HTTPS protocol makes it significantly more difficult for the exchange of data between users and servers to be Decrypted by third parties. Thanks to the encrypted connection, the security level is increased during the storage and transfer of sensitive information. It also provides serious protection against cyber threats such as man in the middle (MITM) attacks.

HTTPS also reinforces the authority and security of servers through its certificate validation mechanism. Digital certificates issued by a certificate authority verify the identity of the server, ensuring that users are communicating with a real and legitimate site. This prevents fraud attempts such as phishing and creates a more reliable internet environment for users. In addition to security, by ensuring data integrity, it guarantees that the transmitted data is delivered unaltered.

Data Encryption

HTTPS ensures the security of data by encrypting the data flow between the user and the server. Various encryption protocols are used in this process to protect the transmitted data against unauthorized access.

Data encryption plays a vital role, especially in protecting sensitive information. This is an essential security measure in all kinds of financial transactions.

For example, SSL/TLS protocols are activated for the secure transfer of card information made on an e-commerce site. These protocols allow the data to be converted from a legible form to an encrypted one.

Thanks to this encryption process, user data remains a meaningless string of characters, even if it is intercepted by any attacker during their journey. Therefore, it is prevented from reading or manipulating this information by unwanted people.

One of the widely used encryption standards is AES (Advanced Encryption Standard), which has also been adopted by the government and the financial sector. The encryption strength provided by this standard makes it quite difficult to break with today’s technologies.

As a result, the encryption layer offered by HTTPS constitutes an important bulwark for the protection of user data. This technology, which is at the center of security strategies, is one of the sine qua non of Internet security.

Authentication and Increasing Trust

HTTPS serves to establish a trusted communication channel between the server and the client. The important thing here is to verify that the server is really the organization or service it claims to be. This trust is ensured by SSL/TLS certificates.

These certificates are issued by trusted certificate authorities (CAs). Verification of certificates increases the possibility of protection from fake sites.

When users connect to a server, the authenticity and reliability of the server are verified through the SSL/TLS certificate. Thanks to this, users receive a confirmation that the connection is secure and can safely continue data exchange. The authentication of the server forms the basis of security and provides a guarantee for users.

SSL/TLS protocols increase the level of security by using strong algorithms for encryption and decryption. Even if an attacker intercepted the data transmission, it would be practically impossible to break this encryption. Furthermore, these protocols build two-sided trust by mutually authenticating both the server and the client. This is both a safeguard against phishing attacks and a prevention of ‘man in the middle’ attacks.

SEO and Performance Effects

HTTPS has positive effects on SEO; Google raises it in the ranking by preferring secure sites. That’s why HTTPS is a critical element for search engine optimization.

Search engines encourage the use of HTTPS with the goal of improving the user experience. Because HTTPS sites are considered more secure, search engines like Google reward such sites and rank them higher in search results. This directly impacts your business success by increasing your site’s visibility and traffic.

In terms of performance, HTTPS also offers advantages for websites. Secure connections support the HTTP/2 protocol, which can improve page load times.

Impact on Search Engine Ranking

HTTPS, Plays a vital role in terms of SEO.

In 2014, Google introduced HTTPS as a ranking signal. And since that introduction, websites implementing HTTPS have started to experience a noticeable rise in search results. Websites that take security seriously are rewarded on Google’s Search Engine Results Pages (SERPs). As a result, security is no longer just a matter of user safety, but also an important point in the algorithms of search engines.

The use of HTTPS is supported by search engines.

Search engines favor HTTPS sites that increase users’ sense of security. Statistics show that sites using the HTTPS protocol rank higher in search rankings than sites that are not secure. This is due to the protection of user data and the emphasis on cryptographic security measures.

HTTPS has a positive effect on sorting performance.

Especially for e-commerce sites, the impact of HTTPS on SEO cannot be ignored. In addition to gaining customer trust, sites with SSL certificates have become preferred by search engines such as Google. As of 2024, browser warnings that warn users who visit an unsecured site cause sites that neglect security to fall in the rankings.

Improving User Experience and Confidence

HTTPS provides the user with a layer of security when performing web-based transactions, which ensures that users’ personal information is protected. For banking and shopping sites in particular, this is essential to ensure that users feel protected.

Designed to focus users on HTTPS, it offers protection against cybercrime such as phishing and fraud.

Individuals feel more comfortable entering their sensitive data based on the secure connection provided by HTTPS, which is a critical factor in increasing customer loyalty and conversion rates. Being able to make transactions in a reliable environment positively affects users’ decision-making mechanisms.

The use of HTTPS on websites increases the trust of users on the site, while at the same time increasing the reputation of the brand. By providing a safe environment, it encourages visitors to stay on the site for longer and return frequently.

Users who are aware of cybersecurity tend to visit sites based on this information, checking whether a website is protected with HTTPS. This situation shows that HTTPS is a factor that contributes not only to security, but also to the user experience and reliability of the site.

As a result, the secure connection offered by HTTPS provides benefits for both users and websites. A well-protected platform, in addition to meeting the expectations of users and gaining trust, also makes it possible to create a reliable presence on the Internet.

Process of Switching to HTTPS

The process of transitioning your website to HTTPS includes steps such as obtaining and configuring a security certificate. First, you need to obtain a suitable SSL/TLS certificate for your site. These certificates are provided by certification bodies (Certificate Authorities – CA). After obtaining the certificate, you need to update the configuration files of your web server to enable the HTTPS protocol. This configuration requires special steps that are usually dependent on the server software.

In addition, it is important that the URLs of existing web pages and resources are updated with ‘https://’ instead of ‘http://’ during the transition process. In addition, it is critical that redirects and link edits are performed correctly in order for users visiting your site to have a smooth experience. These stages require a detailed planning and testing process.

Obtaining an SSL/TLS Certificate

Obtaining an SSL/TLS certificate is one of the cornerstones of a website’s security and is a process that should be handled carefully. The certificate allows you to securely transfer digitally encrypted information and improves the reliability of your website.

The choice of certification body is of critical importance for the reliability of the certificate. A reliable CA will increase the trust in your website.

The acquisition of the certificate includes the steps of domain control and organization verification. Domain control is the process of verifying that the domain name belongs to the person or organization requesting the certificate. Establishment verification, on the other hand, is the confirmation of the legal existence of the company requesting the certificate.

The installation of the acquired SSL/TLS certificate on the server must be performed correctly and carefully. Misconfiguration can lead to vulnerabilities and data breaches. Therefore, the installation process should be handled meticulously and progressed in accordance with security protocols and application standards. After SSL/TLS installation, regular certificate renewals and updates are also mandatory for the sustainability of a secure internet environment.
