Secure Socket Layer Explained

When it comes to computer networking most people will claim zero or near zero knowledge.

And when you speak of terms such as SSL, people think it will be a complicated computer code.

We shall learn what is secure socket layer and how it works in the following article. This will help you learn more about SSL and why is it important in today’s online world.

What is an Secure Socket Layer (SSL)?

A Secure Socket Layer (SSL) certificate is a computer networking protocol.

It helps in securing connections between a server in an unsecure network such as the Internet and a network application client. In simple words, a standard security protocol creates encrypted links between a web server and a browser when communicating online.

SSL certificate makes sure that all data transmitted between web server and browser remains secure by encryption.

Why is SSL Important?

When you speak on the phone, you accept your conversation to be heard only by the person you called. You do not wish your call to be intercepted, or re-routed, or tapped by someone else. And if you have never spoken to the person, you can never be sure if the person speaking to you is actually the right person or someone trying to fool you. When a third person eavesdrops on your call, you never realize it. Someone secretly records or taps your conversation without your permission.

Similarly, when surfing on the Internet, you cannot be sure you have reached the right website or are communicating with the authentic page. This is especially true when you are using a public Wi-Fi, or Hotspot connection.

This raises many security concerns, especially when you are trying to contact servers of your bank and not of a hacker or phishers website. You may never know if any personal, login or credit card details shared online are safe from eavesdroppers or prying eyes.

The only way to make sure you are safe when dealing online is when you see an SSL certificate.

How Does SSL Work?

Now, SSL works in the following way. A browser attempts to connect with a website that is secured with SSL. The browser will need the web server to identify itself. The server will send a copy of its SSL certificate to the browser. Now, the browser will check if the SSL certificate is trustworthy or not. If it is, then it will send a message to the server. In turn, the server will send a digitally signed acknowledgement to the browser and begin with an SSL encrypted session. The data shared between the browser and the server now is encrypted once you see the https in your address bar.

Using SSL certificates gives higher Google rankings to a website. It also helps many online webstores build trust, as the customers are sure that they won’t be cheated. It not just protects your clients, but also helps maintain your brand value in the market. SSL certificate also helps in encrypting browser-to-server and server-to-server communication.

Thus, if you are more likely to carry out financial transactions over the Internet or share sensitive data online, make sure the SSL certificates are in place.
