What is SSL? Why use SSL?

SSL stands for Secure Sockets Layer, a standard technology that allows to establish a secure encrypted connection between a web server (host) and a web browser (client). Let’s learn more about SSL and why to use SSL in the article below.

What is SSL?

SSL stands for Secure Sockets Layer, a standard technology that allows to establish a secure encrypted connection between a web server (host) and a web browser (client).

This connection ensures that the data transferred between the host and the client is maintained in a private, reliable manner. SSL is now used by millions of websites to protect their online transactions with customers.

If you’ve ever visited a website that uses https:// in the address bar, you’ve created a secure connection over SSL. If you have an online store or sell things on your website, SSL will help build trust with your customers and secure the information exchanged between you and your customers.

The importance of SSL

SSL helps protect sensitive information as it travels across computer networks around the world. It provides privacy, strict security and integrity for both the website’s data and the personal information of its visitors.

a. SSL encrypts sensitive information

SSL keeps sensitive information encrypted when sent over the Internet and can only be understood by designated recipients.

When information you send on the Internet is transmitted from computer to computer, and then to a destination server. Any computer between you and the server can see your credit card numbers, account names and passwords, and other sensitive information, as it’s not encrypted with an SSL certificate.

When the SSL Certificate is used, the information becomes unreadable to everyone except the server to which the information is being sent. As a result, hackers and thieves cannot read or steal information.

How is an encrypted connection established?

SSL secure connection is done through the steps below:

• Step 1: You enter or choose a URL: https://www.dienmayxanh.com/ Kinh-nghiem-hay
• Step 2: The web server will receive your request and then send a response that is trying to establish a trusted connection between the web browser and the web server, also known as the “SSL handshake”.
• Step 3: After the SSL Certificate is validated through the SSL handshake, the data transmitted between the web server and the web browser will be encrypted to ensure safety and privacy.

b. SSL provides authenticity

In addition to encryption, a proper SSL certificate also provides authentication. This means you can be sure you’re sending information to the right server and not to some impostor trying to steal your information.

A trusted SSL provider will only issue one SSL Certification to a company, provided that company is confirmed to have passed some identity checks. Some SSL Certifications, such as EV SSL Certificates, require more validation than others.

You can use the SSL Wizard to compare SSL providers, available in most web browsers. The web browser will generate a confirmation that the SSL provider is taking specific actions and is checked by a 3rd party using a standard such as WebTrust.

c. SSL provides trust

Web browsers will give users signals that their connection is secure, which can be a lock icon or a green bar. As a result, customers will trust the website more and increase the ability to buy and stick with the website. The SSL provider will also give you a trust token to make customers trust even more.

d. SSL brings trust to visitors

HTTPS also helps fight phishing attacks. A phishing email is an email sent from a criminal trying to impersonate your website.

This email often has a link to the criminal’s website or uses a Man-in-the-middle attack (the criminal will trick customers into sending them sensitive information) on the website’s domain.

But it is often difficult for an eavesdropper or hacker to obtain an SSL Certificate, so if a website has SSL, they cannot impersonate the website perfectly, and users are less likely to be scammed.

e. SSL is required for PCI Compliance

To accept credit card information on the website, you must pass checks to prove that you are compliant with the standards for payment by card – Payment Card Industry, PCI. One of those requirements is to use SSL Certificate.

f. SSL for SEO

Google has announced that HTTPS will be a criterion for ranking websites. This means that when giving results to searchers, a website with SSL will have priority over a site of the same type but without SSL.

Does SSL have any disadvantages?

– High cost: The cost comes from establishing a trusted infrastructure and confirming identity.

– Next is performance.

The information transmitted will be encrypted, which will consume more server resources than unencrypted information. But, this performance difference becomes noticeable only for websites with a large number of visitors, and can be remedied by using more powerful hardware.

In general, the disadvantages of SSL compared to the advantages, the importance of SSL is insignificant. Using SSL properly will help protect customers, websites, data, build and maintain customer trust, and sell more products.
