Software Model of a Firewall
Švec, Michal ; Tobola, Jiří (referee) ; Puš, Viktor (advisor)
This bachelor thesis deals with stateless packet filters and packet classification algorithms. The main task is to implement a software firewall and measure the speed of packet classification. The implemented classifier uses the Perfect Hash Classification Algorithm. The classifier is implemented in several versions. The C language is used for classifier implementation, Python language is used to create auxiliary data structures. The C language was chosen because of its speed.
HelenOS packet filter
Buchar, Jan ; Děcký, Martin (advisor) ; Horký, Vojtěch (referee)
Packet filtering is an essential feature of any operating system that aims to function as a network router or gateway. This thesis aims to extend the HelenOS operating system to support this functionality. We analyze packet filters present in modern operating systems and implement a HelenOS service that provides a configurable and extendable packet filter. We also modify the HelenOS networking stack so that it allows an arbitrary service to function as a packet filter. We demonstrate the extendability of our implementation on a basic variant of the NAT mechanism. Powered by TCPDF (www.tcpdf.org)
