What is a Denial Of Service Attack (D.O.S) ?
A denial-of-service attack (also, DoS attack) is an attack on a computer system or network that causes a loss of service
to users, typically the loss of network connectivity and services by consuming the bandwidth of the victim network or overloading
the computational resources of the victim system.
For online games the threat is enormous : if someone manage to attack the game servers succesfully, then no player can
enter the game, or all players that were playing are kicked out of the game because the game server has crashed, anyway the
Online Game Industry is in great danger with Denial of Service attacks.
Firewall Monitor : the answer to this threat
The Firewall Monitor is a multithread C++ program embedded in a Linux Firewall and that permits to block in real-time
the attacks to game servers coming from the outside (fake client program, attack tool, ...).
Project Environment :
- Open Source operating system (Red Hat 9.0 – Kernel 2.4.20-8)
- using an object oriented programming langage
- using a free compiler (g++ (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7))
- free debugger : GNU gdb Red Hat
- free profiler : GNU gprof 22.214.171.124.18
- IPtables : iptables v1.2.7a
- design and tests following the DO-178B standard.
The computer running the Firewall and the Firewall Monitor has the following specs :
- DUAL CPU : Pentium 3 Xeon 1.4
GHZ * 2
