A utility for testing firewall settings in a network emulated using the IMUNES system

Ovaj rad predstavlja alat za testiranje postavki vatrozida unutar emulirane mreže u sustavu Imunes. IMUNES je otvoreno simulacijsko okruženje koje omogućuje istraživanje i razvoj mrežnih arhitektura i protokola. Alat se sastoji od PortScannera i PortListenera, koji omogućuju skeniranje mreže i slušanje mrežnih paketa. Oba programa su napisana u programskom jeziku Go, koji je jednostavan, efikasan i podržava konkurentnost. Go je odabran zbog brzine provjere ispravnosti rješenja vježbe.This paper presents a tool for testing firewall configurations within an emulated network using Imunes. IMUNES is an open simulation environment for exploring and developing network architectures and protocols. The tool consists of PortScanner and PortListener, enabling network scanning and packet listening. Both programs are implemented in the Go programming language, known for its simplicity, efficiency, and concurrency support. Go was chosen for its speed in verifying exercise solutions
