How to Implement Network Threats Analysis in OMNeT++
To implement network threats analysis in OMNeT++ has needs to generate the emulation settings where the numerous network threats are established and measures to familiarize their characteristics, impact and the possible prevention strategies and this process is usually defined to monitor the network traffic, identifying the anomalies or the malicious activities and measure the efficiency of the countermeasures. The given below is the brief structures to implement the network threat analysis in OMNeT++:
Steps to Implement Network Threats Analysis in OMNeT++
- Define the Network Environment:
- Set up a network simulation that contains numerous nodes like workstations, servers, routers, and a Threat Analysis Module (TAM) that observes the network for various kinds of threats.
simple WorkstationModule
{
parameters:
@display(“i=block/pc”);
gates:
inout ethg;
}
simple ServerModule
{
parameters:
@display(“i=block/server”);
gates:
inout ethg;
}
simple RouterModule
{
parameters:
@display(“i=block/router”);
gates:
inout ethg;
}
simple ThreatAnalysisModule
{
parameters:
@display(“i=block/shield”);
gates:
inout monitorGate;
}
network ThreatAnalysisNetwork
{
submodules:
workstation: WorkstationModule;
server: ServerModule;
router: RouterModule;
tam: ThreatAnalysisModule;
connections:
workstation.ethg <–> router.ethg[0];
server.ethg <–> router.ethg[1];
router.ethg[2] –> tam.monitorGate; // Mirror traffic to the TAM
}
- Simulate Various Network Threats:
- Introduce numerous kinds of network threats like DDoS attacks, malware propagation, unauthorized access attempts, or data exfiltration. Each threat can be denoted by particular traffic patterns or characteristics.
class WorkstationModule : public cSimpleModule {
protected:
virtual void initialize() override {
scheduleAt(simTime() + par(“startTime”), new cMessage(“generateTraffic”));
}
virtual void handleMessage(cMessage *msg) override {
if (strcmp(msg->getName(), “generateTraffic”) == 0) {
generateTraffic();
scheduleAt(simTime() + par(“interval”), msg);
} else {
cPacket *pkt = check_and_cast<cPacket*>(msg);
processPacket(pkt);
delete pkt;
}
}
void generateTraffic() {
cPacket *normalPkt = new cPacket(“normalTraffic”);
send(normalPkt, “ethg$o”);
if (uniform(0, 1) < par(“attackProbability”)) {
cPacket *attackPkt = new cPacket(“attackTraffic”);
attackPkt->addPar(“threatType”) = intuniform(0, 2); // Different threat types
send(attackPkt, “ethg$o”);
EV << “Simulating network threat” << endl;
}
}
void processPacket(cPacket *pkt) {
EV << “Packet received: ” << pkt->getName() << endl;
}
};
- Implement Threat Detection and Analysis Logic:
- Develop the Threat Analysis Module (TAM) that observe the network for different threats, evaluate the traffic, and categorizes the identified threats based on predefined rules or behavioural patterns.
class ThreatAnalysisModule : public cSimpleModule {
private:
int ddosDetections = 0;
int malwareDetections = 0;
int unauthorizedAccessDetections = 0;
protected:
virtual void handleMessage(cMessage *msg) override {
cPacket *pkt = check_and_cast<cPacket*>(msg);
int threatType = pkt->par(“threatType”).intValue();
switch (threatType) {
case 0:
detectDDoS(pkt);
break;
case 1:
detectMalware(pkt);
break;
case 2:
detectUnauthorizedAccess(pkt);
break;
default:
break;
}
delete pkt;
}
void detectDDoS(cPacket *pkt) {
ddosDetections++;
EV << “DDoS threat detected: ” << pkt->getName() << endl;
recordThreat(“DDoS”, pkt);
}
void detectMalware(cPacket *pkt) {
malwareDetections++;
EV << “Malware threat detected: ” << pkt->getName() << endl;
recordThreat(“Malware”, pkt);
}
void detectUnauthorizedAccess(cPacket *pkt) {
unauthorizedAccessDetections++;
EV << “Unauthorized access detected: ” << pkt->getName() << endl;
recordThreat(“Unauthorized Access”, pkt);
}
void recordThreat(const std::string &type, cPacket *pkt) {
// Record threat details
EV << “Recording threat of type: ” << type << ” from packet: ” << pkt->getName() << endl;
// Implement additional logging or analysis here
}
virtual void finish() override {
recordScalar(“DDoS Detections”, ddosDetections);
recordScalar(“Malware Detections”, malwareDetections);
recordScalar(“Unauthorized Access Detections”, unauthorizedAccessDetections);
EV << “Threat analysis complete.” << endl;
}
};
- Implement Response Mechanisms:
- After detecting and measuring a threat, the TAM can trigger response mechanisms, like logging the event, alerting network administrators, or automatically taking actions such as blocking traffic or isolating compromised nodes.
class ResponseModule : public cSimpleModule {
protected:
virtual void handleMessage(cMessage *msg) override {
cPacket *pkt = check_and_cast<cPacket*>(msg);
if (pkt->par(“isThreat”).boolValue()) {
EV << “Blocking threat packet: ” << pkt->getName() << endl;
delete pkt;
} else {
send(pkt, “ethg$o”);
}
}
};
- Simulate and Evaluate Threat Analysis:
- Run the simulation with diverse threat scenarios to measure how effectively the TAM detects and categorizes threats. Measure the parameters such as detection accuracy, false positives, and the time taken to respond to various threats.
virtual void finish() override {
// Collect and record metrics about the threat analysis system’s performance
}
Example Scenario: Detecting and Responding to Multiple Threats
In this scenario, the TAM monitors network traffic for different kinds of threats that has DDoS attacks, malware propagation, and unauthorized access attempts. When a threat is identified, the TAM categorizes it and logs the details. Depending on the severity and type of threat, the TAM influence the response mechanisms, like blocking traffic or sending alerts.
