How to prevent somebody's domain from pointing to my droplet?

Posted February 1, 2020
DigitalOcean Ubuntu 18.04 WordPress Apache

Hi, developers

I have recently moved my site from shared hosting to the Digital ocean. And believe or not it was a tough step for me as I don’t have deep knowledge about the server configuration.

After two months, everything is going well so far, but recently, I have started to face a security issue.

Someone has pointed their domain to my IP. I.e domain.com is also accessible from freedomain.com. I have got to know about the cause and it pretty much hurting my page ranking. My issue is something like this

Can anybody suggest how to deal with this?

PS: I can’t try this How to Rewrite URLs with mod_rewrite for Apache on Ubuntu 18.04

My server configuration: Ubuntu 18.04 Apache Wordpress

Thanks. Rohit

Hello,

What I could suggest here is:

Create a Virtual Host for your website, here is a step by step guide on how to do that:

https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-16-04

After that set your Default Virtual Host to deny all traffic. For example, you could use something like this:

<VirtualHost *:80>
    <Location />
    Order deny,allow
    Deny from all
    </Location>

    ...
</VirtualHost>

That way if a domain name does not have a Virtual Host on your server, it would be routed to the default Virtual Host which would result in a 403 Forbidden error.

Hope that this helps! Let me know if you have any questions. Regards, Bobby
