Re: port scan--"filtered" ports

[Andre Pawlowski <sqall () h4des org>]

This means, that nmap cannot check these ports because you are filtered.
So it is possible that there is a service running and reachable from
other IP-addresses. But it could also be that there is no service running.

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.
