Can i use the Unix/linux security on the windows 2003 server, i wan to convert the Unix/linux security protocols into the windows base security system..

I'm setting up my own network security for my own home server. I want to know what things I would need to do in order to improve network security. My questions are:

Do I need to care about DDOS attacks even when the site is new?

Should I encrypt my website or leave it be? I don't require readers to log-in to my site nor have a shopping cart.

Any other advice?

DDOS attacks are quite annoying for my home server. I get DDOS attacks at least twice a week and is killing my websites. What can I do to mitigate DDOS attacks under a budget? If possible, can I be trained to mitigate DDOS attacks on my own?
