Question about Site / Server Security

[ebizwildfire]

Greetings,

The other day my entire server was hacked and all 27 of my sites had a black screen with a green skull and crossbones, and a note letting me know I had been hacked. Acckkkk!

Thank goodness, my host provider was able to help me restore my sites.

I am in the process of a huge event and hundreds of people are coming to my site every day. My host provider helped me install plugins to help speed up page views and reduce throttling.

MY QUESTION IS: What else can I do to protect my site and protect access to my hosting account.

Since they got into ALL of my sites at once, it seems that they access more than just my wordpress site.

Please help me protect my site as I'm sure this information will be useful for other forum members as well.

With MUCH appreciation,
D'vorah
