Proxy servers in Internet
Henek, Jan ; Burda, Karel (referee) ; Komosný, Dan (advisor)
The goal of this paper is to analyze the representation of proxy servers in cyber attacks conducted by Internet. For this purpose I used method which compares tested IP address with database of open proxy servers. I assembled a list of IP address taken from the blacklist of cyber attacks committed in 2015. Then I checked this list with the created program Proxy checker and compared them with a database of open proxy servers. By measurement I demonstrate the inefficacy of this method for reverse detection of proxy servers in the IP list of past attacks.
