SSL/TLS: the importance of security protocols for data protection on the internet 

In today's world, internet security is paramount, especially when it comes to sensitive information such as banking data and personal information. With the exponential increase in e-commerce, the need to keep this information protected has become even more critical. To ensure the security of information, the SSL (Secure Sockets Layer) and TLS (Transport Layer Security) protocols were developed. In this article, we will better understand how SSL and TLS work and the importance of using them on websites that deal with sensitive information.

WHAT IS SSL AND TLS?

SSL stands for Secure Sockets Layer, a security protocol created by Netscape Communications Corporation. TLS stands for Transport Layer Security, developed by the Internet Engineering Task Force (IETF), and works basically the same way as SSL. In fact, the two terms are used to refer to the same process.

SSL/TLS serves, among many other things, to ensure the privacy of communication between client and server. By implementing the SSL protocol on your website, you can obtain a digital certificate for use by the target server to confirm your site's identity.

HOW DO SSL AND TLS PROTOCOLS WORK?

SSL and TLS are ways to encrypt data traveling between two computers (client and server). They use the Handshake process to establish a secure connection with the appropriate parameters. The client starts by requesting to connect to the server. From there, it needs to show who it is, meaning it sends a certificate. If this certificate is correct, the client begins to generate a random key to send to the server. From there, the two can exchange data using encryption, making communication even more secure.

WHY ARE THESE PROTOCOLS SO IMPORTANT?

SSL/TLS are cryptographic protocols that provide most of the secure Internet connections today. They encrypt the data exchanged between the client and the server, making it difficult for hackers to attack and steal information. Additionally, they also verify the identity of the server, allowing users to know they are connecting to the correct server. Therefore, the use of these protocols in E-Commerce and Marketplaces is indispensable.

HOW TO SET UP AND ADD AN SSL AND TLS PROTOCOL TO YOUR SITE

To set up an SSL/TLS protocol on your site, you need to acquire and install an SSL/TLS certificate issued by a trusted certification authority, configure your SSL key and certificate on the server, and configure the server to direct web requests to the SSL port. The process can be complex depending on the web server you are using, but with a basic understanding and following step-by-step instructions, it is possible to make a secure setup. However, to avoid problems, the best thing to do is to hire an experienced developer to apply the correct settings.

HOW MUCH DOES AN SSL CERTIFICATION COST?

SSL certification is indispensable for any website on the internet. The cost varies depending on the packages chosen and their components, and can range from $9 to $150 USD per year. Premium certificates, on the other hand, can cost thousands of dollars. However, Easy ComTec offers pre-configured SSL certificates for only R$100 on E-Commerce, Marketplaces, and any website developed by us.
