UGN Security Forums UGN Security: Knowledge Base Graphics & Multimedia encrypted web servers

i do appologise for the absence of the forum,

i belive that any of you are a handy programer and if i could ask you few questions if i may or maybe one it is concerning websites beieng hacked and the code changed in them to alter the site when people see it on line,defaceing them

me and the friend has bought ezgenerator online with cc card and i would like to know the code in any website if i had a website to go online is there anyway or ftp http servers that are unbreakable and what would be the best way of defending a website form outside attacks is there any or could you tell me if i was to ping a website and get a reponse from the dns could you tell me how is it that they are able to get the website reconised as no ports open not even http they have closed all ports how do people do this and what is entialed i would be very gratefull if you could awnser this question been bugging me a long time about the ports and stuff but the really asking best way to protect website code or website from attacks

I'm not sure that I understand anything that you said...

When you ping a website, your computer is sending ICMP Echo Packets, it is up to the computer (or device) that receive these "Echo Requests" to respond. Unlike TCP or UDP which specify a virtual "port" which is really just some number that computers use to help distinguish one packet (piece of network data) from another. So even if a computer has no ports "open" (which is really just a simple way of saying they respond to a TCP SYN request) they can still reply to an ICMP Echo or "ping". Hope this helps... For more information I suggest you read the IP, TCP, and ICMP rfcs.

IP: http://www.faqs.org/rfcs/rfc791.html
ICMP: http://www.faqs.org/rfcs/rfc792.html
TCP: http://www.faqs.org/rfcs/rfc793.html

Notice its 791, 792, 793... they're all very closely related which is why its easy to confuse their inner workings.

As for secure webservers, try using the latest "Stable" version of Apache. Its a free open source web server and its pretty much what everyone uses. Up to date software is an important factor in security. Once you read those RFCs and get a better understanding for the way the internet works, you may go on to read about firewalls, and how they can help you to secure your websites.
