How to Calculate Network Compliance in omnet++
To calculate the network compliance in OMNeT++ has encompasses to calculating whether the network’s behaviour aligns with predefined policies, regulations or standards. Network compliance can include security policies, quality of service (QoS) requirements, access controls, and other operational standards. The following steps are help to implement and calculate network compliance in OMNeT++.
Step-by-Step Implementations:
- Understand Network Compliance
Network compliance denotes to the adherence of the network and its components to created rules and policies. It should contain:
- Security Policies: Make sure that only authorized users and devices have access to specific network resources.
- Quality of Service (QoS): Assuring that network performance metrics like latency, jitter, and packet loss meet indicated thresholds.
- Regulatory Compliance: Observing to industry regulations like GDPR, HIPAA, or PCI-DSS.
- Set up a Network with Compliance Points
Make a network topology where compliance points like firewalls, routers, or servers enforce and observe compliance with policies in OMNeT++. These points will be answerable for make sure that network activities follow to the defined rules.
Example: Define a Network with Compliance Points in NED
network ComplianceNetwork {
submodules:
client: Client;
firewall: ComplianceFirewall; // Firewall with compliance enforcement
server: Server;
connections:
client.out++ –> firewall.in++;
firewall.out++ –> server.in++;
}
- Implement Compliance Enforcement Logic
In the OMNeT++ module demonstrating the compliance point like a firewall, execute the logic to enforce policies and monitor compliance. The module should track whether each network activity complies with the defined rules.
Example: Implementing Compliance in a Firewall
#include <omnetpp.h>
using namespace omnetpp;
class ComplianceFirewall : public cSimpleModule {
private:
int compliantPackets = 0;
int nonCompliantPackets = 0;
int totalPackets = 0;
std::ofstream complianceLogFile;
protected:
virtual void initialize() override {
// Open a compliance log file to store the compliance records
complianceLogFile.open(“compliance_log.txt”);
}
virtual void handleMessage(cMessage *msg) override {
totalPackets++;
// Check compliance with the network policy
if (isCompliant(msg)) {
compliantPackets++;
send(msg, “out”); // Allow the packet through
logComplianceEvent(msg, “Compliant”);
} else {
nonCompliantPackets++;
logComplianceEvent(msg, “Non-compliant”);
delete msg; // Drop the non-compliant packet
}
}
bool isCompliant(cMessage *msg) {
// Implement your compliance check logic here
// Example: Check if the message type or content complies with the policy
return strcmp(msg->getName(), “compliantRequest”) == 0;
}
void logComplianceEvent(cMessage *msg, const char *status) {
// Get the simulation time and the module’s name
simtime_t currentTime = simTime();
const char *moduleName = getFullPath().c_str();
// Log the event to the compliance log file
complianceLogFile << currentTime << ” – ” << moduleName << ” – ” << status << “: ” << msg->getName() << std::endl;
// Optionally, log to the simulation output
EV << currentTime << ” – ” << moduleName << ” – ” << status << “: ” << msg->getName() << std::endl;
}
virtual void finish() override {
// Record compliance statistics
recordScalar(“Compliant Packets”, compliantPackets);
recordScalar(“Non-compliant Packets”, nonCompliantPackets);
recordScalar(“Total Packets”, totalPackets);
// Close the compliance log file at the end of the simulation
complianceLogFile.close();
}
};
Define_Module(ComplianceFirewall);
- Simulate Traffic and Monitor Compliance
Make traffic from the client to the server over the compliance firewall. The firewall will implement compliance and log whether each packet complies with the defined policies.
Example: Traffic Simulation with Compliance Enforcement
class Client : public cSimpleModule {
protected:
virtual void initialize() override {
// Start generating both compliant and non-compliant requests
scheduleAt(simTime() + par(“sendInterval”).doubleValue(), new cMessage(“compliantRequest”));
scheduleAt(simTime() + par(“sendInterval”).doubleValue() + 1, new cMessage(“nonCompliantRequest”));
}
virtual void handleMessage(cMessage *msg) override {
// Send the request to the firewall for compliance checking
send(msg, “out”);
}
};
- Monitor and Analyse Compliance Data
The logs made by the compliance points can be analysed to measure the network’s adherence to policies. Metrics like the number of compliant and non-compliant packets can be used to analyse compliance rates and identify areas of concern.
Example: Calculating Compliance Rate
class ComplianceFirewall : public cSimpleModule {
private:
int compliantPackets = 0;
int nonCompliantPackets = 0;
int totalPackets = 0;
protected:
virtual void handleMessage(cMessage *msg) override {
totalPackets++;
if (isCompliant(msg)) {
compliantPackets++;
send(msg, “out”);
} else {
nonCompliantPackets++;
delete msg;
}
}
virtual void finish() override {
double complianceRate = (double)compliantPackets / totalPackets * 100.0;
recordScalar(“Compliance Rate (%)”, complianceRate);
}
};
- Analyze Compliance Effectiveness
Examine the effectiveness of the compliance enforcement after running the simulation:
- Compliance Rate: The percentage of network activities that observe with the policies.
- Policy Violation Incidents: The number of non-compliant activities that happened.
- Impact on Network Performance: The impact of compliance enforcement on latency, throughput, and other performance metrics.
- Advanced Compliance Features
For more comprehensive compliance monitoring, we may involve:
- Implement Role-Based Compliance: Implement compliance based on the roles of users or devices in the network.
- Simulate Dynamic Compliance Policies: Modify compliance rules based on network conditions or security alerts.
- Implement Real-Time Compliance Monitoring: Endlessly observe and report on compliance in real-time, with alerts for violations.
- Example Scenario
In the given example, the ComplianceFirewall module logs and enforces compliance on each packet passing over it. Compliance metrics like the number of compliant and non-compliant packets, along with the overall compliance rate, are noted and analysed.
network ComplianceExample {
submodules:
client: Client;
firewall: ComplianceFirewall;
server: cModule;
connections:
client.out++ –> firewall.in++;
firewall.out++ –> server.in++;
}
- Post-Simulation Compliance Analysis
To observe the recorded compliance metrics, like the compliance rate, non-compliant packets, and total packets. This analysis will support to know how well the network adheres to the defined policies and where developments may be required.
