When you host a website, you host tonnes of data on the hosting servers. Considering the rising cases of data breaches and cyber attacks, data protection becomes highly critical. As a website owner, you are responsible for securing the customer data that they entrust you with. This is why data security takes precedence for a website owner.
Data security refers to an infrastructural setup where data is stored only where the owner wants it, and no one has access to it without the owner’s permission. Though this is a bit of an oversimplification, it’s the basic idea. You store your site’s data on a server, and no one can access it unless they have your permission.
