A DOS or DDOS is a denial of service attack, or distributed denial of 
service attack. You appear to be on a different wave length here, so I 
wanted to throw that out. DDOS and DOS is done usually by flooding a 
service or application with packets.

If you want to protect a service (or a server), you can set up rate 
limiting, etc that could help. You will never fully be able to prevent 
against DDOS since people can just use more systems, but you can at 
least start.

You also mentioned a capcia. If you are trying to protect a web 
application, you can also set up some sort of blacklist. make people 
register to log in, limit number of requests based on IP etc etc. It all 
really depends honestly on what you are trying to do; as I said before, 
you mention DDOS/DOS then you mention capcias.

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
