WHAT IS WORDPRESS MULTISITE HTTPS, AND HOW DOES IT WORK?
This leads us into the next piece which is HTTPS. So, what is HTTPS and why should you care? HTTPS stands for Hypertext Transfer Protocol. It is common to encrypt the data and information through end-to-end routes that you send and receive from different sites. You can be protected from losing your personal data to the middleman or ISP’s in the connection through this.
In short, through harmful means, someone can hack the biased connection between you and the server and take in all the vital information like credit card numbers without even realizing it. However, with the aid of HTTPS, your data over the Internet is secured and adequately encrypted, and even your domain name is not shared with unknown sources.
So, it takes the encrypted data created by SSL/TLS and puts it on a bus. Then drives that bus of encrypted data back and forth between your WordPress site and the users’ browser. If the WordPress multisite SSL data is intercepted it cannot be read by anyone and therefore remains private. This is the safest way to create a WordPress multisite SLL with the least amount of drawbacks.
As we discussed before, encryption is a vital component that one should consider for proper security on the Internet. The HTTPS in your website or browser represent appropriate encryption as you connect with your server.
The third-party sources can see the connection but won’t read to decode the information passing through. In real life, let’s say that the package you will be sending to someone has been locked in a box with a specific key provided by the person/server.
As you send that package in the closed container, no one can open it, even if they receive one. But the person that already has the key will be able to open it with ease. This is the way through how to make website secure WordPress as HTTPS works within cyberspace. And this is the reason why you should set up SSL (HTTPS) on WordPress multisite
How to secure the communication on my WordPress Multisite instance?
First to secure WordPress multisite SSL, you need an SSL Certificate. You can purchase an SSL certificate or on most hosting plans you can use Let’s Encrypt to generate a free one. An SSL Certificate is like a key you would use for your house. Just like the key for your front door, you use a certificate to lock the door and protect the data. The only one with a “key” can access the content you create.
A certificate is the key but instead of locking your front door it is locking/encrypting the data on your website to be sent to someone who wants to access it. What you don’t see under the hood is that any user who wants to access your website securely gets a key.
This authenticates your site and proves they are communicating with the intended website, it authorizes them and allows them to access the content. It also provides encryption of the data as well as the integrity of the data.
In other words, the data cannot be viewed by someone who is unauthorized and the data cannot be modified without being detected. This type of key is a public key, which means that anyone who is authorized can access the content. The content is delivered in a secure manner so no-one can alter it, everyone gets authorized to view the content.
