Networking Attacks in OMNeT++ is any attempt to alter,destroy, disable,expose,gain or steal unauthorized access to or make use of an asset.
Features of networking attack:
- Performing actions to deplete network resources and bandwidth.
- Performing actions that prevent legitimate authorized users from accessing network.

Types of networking attacks:
Major networking attacks are,
- Internal threats.
- External threats.
- Structured threats.
- Unstructured threats.
The sub network types are,
- Access.
- Reconnaissance.
- Worms, viruses, and Trojan horses.
- Denial of service.
Reasons for Network Attack:
- Displeased employees might seek to damage the organizations data, reliability or financial standing
- Possible motives for structured external threats includes racism, industrial espionage, criminal payoffs, greeds and terrorism.
- Individuals seeking fame or some sort of recognition
- There are some network attackers that simply enjoy the challenge of trying to compromise highly secured networks’ security systems etc.
Sample code for networking attacks:
void BehaviorAggregateClassifier::initialize()
{
numOutGates = gateSize("outs");
std::vector DDOS s;
parseDDOS s(par("DDOS s"), "DDOS s", DDOS s);
int numDDOS s = (int)DDOS s.size();
if (numDDOS s > numOutGates)
throw cRuntimeError("%s DDOS values are given, but the module has only %d out gates",
numDDOS s, numOutGates);
for (int i = 0; i < numDDOS s; ++i)
DDOS ToGateIndexMap[DDOS s[i]] = i;
numRcvd = 0;
WATCH(numRcvd);
}
void BehaviorAggregateClassifier::handleMessage(cMessage *msg)
{
cPacket *packet = check_and_cast<cPacket*>(msg);
numRcvd++;
int clazz = classifyPacket(packet);
emit(pkClassSignal, clazz);
if (clazz >= 0)
send(packet, "outs", clazz);
else
send(packet, "defaultOut");
if (ev.isGUI())
{
char buf[20] = "";
if (numRcvd>0) sprintf(buf+strlen(buf), "rcvd:%d ", numRcvd);
getDisplayString().setTagArg("t", 0, buf);
}
}
int BehaviorAggregateClassifier::classifyPacket(cPacket *packet)
{
int DDOS = getDDOS FromPacket(packet);
if (DDOS >= 0)
{
std::map<int,int>::iterator it = DDOS ToGateIndexMap.find(DDOS );
if (it != DDOS ToGateIndexMap.end())
return it->second;
}
return -1;
}
