To implement the serverless computing security in ns3 has needs to encompasses to emulate the secure communication among the serverless function nodes, edge devices and the possibly an attacker and the security mechanism contains an encryption, authentication, and intrusion detection. The given below is the detailed procedure on how to implement the serverless computing security in ns3 tool:
Step-by-Step Implementation
Step 1: Set Up the ns3 Environment
Install ns3 in the computer.
Step 2: Define the Network Topology
Generate a network topology that contains nodes representing edge devices, serverless function nodes, and possibly an attacker.
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/point-to-point-module.h”
#include “ns3/applications-module.h”
using namespace ns3;
NS_LOG_COMPONENT_DEFINE (“ServerlessComputingSecurityExample”);
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer edgeDevices;
edgeDevices.Create (2); // Edge devices
NodeContainer serverlessNodes;
serverlessNodes.Create (2); // Serverless function nodes
NodeContainer attacker;
attacker.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“5Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (edgeDevices.Get (0), serverlessNodes.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (edgeDevices.Get (1), serverlessNodes.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (serverlessNodes.Get (0), serverlessNodes.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (serverlessNodes.Get (1), attacker.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (edgeDevices);
stack.Install (serverlessNodes);
stack.Install (attacker);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure applications…
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Step 3: Simulate Communication
To simulate communication between edge devices and serverless function nodes generate the applications.
Edge Device Application:
class EdgeDeviceApplication : public Application {
public:
EdgeDeviceApplication () : m_socket (0) {}
virtual ~EdgeDeviceApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&EdgeDeviceApplication::HandleRead, this));
Simulator::Schedule (Seconds (2.0), &EdgeDeviceApplication::SendData, this);
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void SendData () {
Ptr<Packet> packet = Create<Packet> ((uint8_t*)”edge-data”, 9);
m_socket->SendTo (packet, 0, InetSocketAddress (Ipv4Address (“10.1.1.2”), 8080)); // Send to a serverless node
Simulator::Schedule (Seconds (5.0), &EdgeDeviceApplication::SendData, this);
}
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Edge Device received: ” << packet->GetSize ());
}
}
Ptr<Socket> m_socket;
};
0Serverless Function Node Application:
class ServerlessNodeApplication : public Application {
public:
ServerlessNodeApplication () : m_socket (0) {}
virtual ~ServerlessNodeApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 8080);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&ServerlessNodeApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
NS_LOG_INFO (“Serverless Node received: ” << packet->GetSize ());
// Process data and respond if necessary
std::string responseData = “processed-data”;
Ptr<Packet> responsePacket = Create<Packet> ((uint8_t*)responseData.c_str (), responseData.size ());
m_socket->SendTo (responsePacket, 0, from);
}
}
Ptr<Socket> m_socket;
};
Step 4: Implement Security Mechanisms
Simulate security mechanisms such as encryption, authentication, and intrusion detection.
Authentication:
class AuthApplication : public Application {
public:
AuthApplication () : m_socket (0) {}
virtual ~AuthApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 7070);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&AuthApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
if (Authenticate (data)) {
NS_LOG_INFO (“Authentication successful from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
ForwardPacket (packet);
} else {
NS_LOG_WARN (“Authentication failed from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
}
}
}
bool Authenticate (const std::string& data) {
// Simplified authentication logic
return data == “valid-credentials”;
}
void ForwardPacket (Ptr<Packet> packet) {
Ptr<Socket> socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress remote = InetSocketAddress (Ipv4Address (“10.1.1.2”), 8080); // Forward to another node
socket->Connect (remote);
socket->Send (packet);
socket->Close ();
}
Ptr<Socket> m_socket;
};
Encryption:
class EncryptionApplication : public Application {
public:
EncryptionApplication () : m_socket (0) {}
virtual ~EncryptionApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 6060);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&EncryptionApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
std::string decryptedData = Decrypt (data);
NS_LOG_INFO (“Received encrypted data: ” << data << “, decrypted data: ” << decryptedData);
}
}
std::string Decrypt (const std::string& data) {
// Simplified decryption logic
return data; // Assume data is already decrypted for simplicity
}
Ptr<Socket> m_socket;
};
Intrusion Detection System (IDS):
class IDSApplication : public Application {
public:
IDSApplication () : m_socket (0) {}
virtual ~IDSApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 5050);
m_socket->Bind (local);
m_socket->SetRecvCallback (MakeCallback (&IDSApplication::HandleRead, this));
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void HandleRead (Ptr<Socket> socket) {
Ptr<Packet> packet;
Address from;
while ((packet = socket->RecvFrom (from))) {
std::string data = std::string ((char*) packet->PeekData ());
if (DetectIntrusion (data)) {
NS_LOG_WARN (“Intrusion detected from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
} else {
NS_LOG_INFO (“Normal traffic from ” << InetSocketAddress::ConvertFrom (from).GetIpv4 ());
}
}
}
bool DetectIntrusion (const std::string& data) {
// Simplified intrusion detection logic
return data == “malicious-pattern”;
}
Ptr<Socket> m_socket;
};
Step 5: Deploy Applications
Instantiate and deploy the applications on the appropriate nodes in your network:
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer edgeDevices;
edgeDevices.Create (2); // Edge devices
NodeContainer serverlessNodes;
serverlessNodes.Create (2); // Serverless function nodes
NodeContainer attacker;
attacker.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“5Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (edgeDevices.Get (0), serverlessNodes.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (edgeDevices.Get (1), serverlessNodes.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (serverlessNodes.Get (0), serverlessNodes.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (serverlessNodes.Get (1), attacker.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (edgeDevices);
stack.Install (serverlessNodes);
stack.Install (attacker);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure the Edge Device application
for (uint32_t i = 0; i < edgeDevices.GetN (); ++i) {
Ptr<EdgeDeviceApplication> edgeApp = CreateObject<EdgeDeviceApplication> ();
edgeDevices.Get (i)->AddApplication (edgeApp);
edgeApp->SetStartTime (Seconds (1.0));
edgeApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Serverless Node application
for (uint32_t i = 0; i < serverlessNodes.GetN (); ++i) {
Ptr<ServerlessNodeApplication> serverlessApp = CreateObject<ServerlessNodeApplication> ();
serverlessNodes.Get (i)->AddApplication (serverlessApp);
serverlessApp->SetStartTime (Seconds (1.0));
serverlessApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Auth application
Ptr<AuthApplication> authApp = CreateObject<AuthApplication> ();
serverlessNodes.Get (1)->AddApplication (authApp);
authApp->SetStartTime (Seconds (1.0));
authApp->SetStopTime (Seconds (20.0));
// Create and configure the Encryption application
Ptr<EncryptionApplication> encryptionApp = CreateObject<EncryptionApplication> ();
serverlessNodes.Get (1)->AddApplication (encryptionApp);
encryptionApp->SetStartTime (Seconds (1.0));
encryptionApp->SetStopTime (Seconds (20.0));
// Create and configure the IDS application
Ptr<IDSApplication> idsApp = CreateObject<IDSApplication> ();
serverlessNodes.Get (1)->AddApplication (idsApp);
idsApp->SetStartTime (Seconds (1.0));
idsApp->SetStopTime (Seconds (20.0));
Simulator::Run ();
Simulator::Destroy ();
return 0;
}
Step 6: Simulate an Attack
To test the security mechanisms, simulate an attack from the attacker node:
class AttackerApplication : public Application {
public:
AttackerApplication () : m_socket (0) {}
virtual ~AttackerApplication () {}
protected:
virtual void StartApplication () {
m_socket = Socket::CreateSocket (GetNode (), UdpSocketFactory::GetTypeId ());
m_peer = InetSocketAddress (Ipv4Address (“10.1.1.2”), 8080); // Target serverless node
m_socket->Connect (m_peer);
Simulator::Schedule (Seconds (3.0), &AttackerApplication::SendMaliciousPacket, this);
}
virtual void StopApplication () {
if (m_socket) {
m_socket->Close ();
m_socket = 0;
}
}
private:
void SendMaliciousPacket () {
std::string maliciousData = “malicious-pattern”; // Simplified malicious pattern
Ptr<Packet> packet = Create<Packet> ((uint8_t*)maliciousData.c_str (), maliciousData.size ());
m_socket->Send (packet);
}
Ptr<Socket> m_socket;
Address m_peer;
};
int main (int argc, char *argv[]) {
CommandLine cmd;
cmd.Parse (argc, argv);
// Create nodes
NodeContainer edgeDevices;
edgeDevices.Create (2); // Edge devices
NodeContainer serverlessNodes;
serverlessNodes.Create (2); // Serverless function nodes
NodeContainer attacker;
attacker.Create (1); // Attacker node
// Create point-to-point links
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“5Mbps”));
pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));
NetDeviceContainer devices;
devices.Add (pointToPoint.Install (NodeContainer (edgeDevices.Get (0), serverlessNodes.Get (0))));
devices.Add (pointToPoint.Install (NodeContainer (edgeDevices.Get (1), serverlessNodes.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (serverlessNodes.Get (0), serverlessNodes.Get (1))));
devices.Add (pointToPoint.Install (NodeContainer (serverlessNodes.Get (1), attacker.Get (0))));
// Install Internet stack
InternetStackHelper stack;
stack.Install (edgeDevices);
stack.Install (serverlessNodes);
stack.Install (attacker);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase (“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign (devices);
// Create and configure the Edge Device application
for (uint32_t i = 0; i < edgeDevices.GetN (); ++i) {
Ptr<EdgeDeviceApplication> edgeApp = CreateObject<EdgeDeviceApplication> ();
edgeDevices.Get (i)->AddApplication (edgeApp);
edgeApp->SetStartTime (Seconds (1.0));
edgeApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Serverless Node application
for (uint32_t i = 0; i < serverlessNodes.GetN (); ++i) {
Ptr<ServerlessNodeApplication> serverlessApp = CreateObject<ServerlessNodeApplication> ();
serverlessNodes.Get (i)->AddApplication (serverlessApp);
serverlessApp->SetStartTime (Seconds (1.0));
serverlessApp->SetStopTime (Seconds (20.0));
}
// Create and configure the Auth application
Ptr<AuthApplication> authApp = CreateObject<AuthApplication> ();
serverlessNodes.Get (1)->AddApplication (authApp);
authApp->SetStartTime (Seconds (1.0));
authApp->SetStopTime (Seconds (20.0));
// Create and configure the Encryption application
Ptr<EncryptionApplication> encryptionApp = CreateObject<EncryptionApplication> ();
serverlessNodes.Get (1)->AddApplication (encryptionApp);
encryptionApp->SetStartTime (Seconds (1.0));
encryptionApp->SetStopTime (Seconds (20.0));
// Create and configure the IDS application
Ptr<IDSApplication> idsApp = CreateObject<IDSApplication> ();
serverlessNodes.Get (1)->AddApplication (idsApp);
idsApp->SetStartTime (Seconds (1.0));
idsApp->SetStopTime (Seconds (20.0));
// Create and configure the Attacker application
Ptr<AttackerApplication> attackerApp = CreateObject<AttackerApplication> ();
attacker.Get (0)->AddApplication (attackerApp);
attackerApp->SetStartTime (Seconds (3.0));
attackerApp->SetStopTime (Seconds (4.0));
Simulator::Run ();
Simulator::Destroy ();
return 0;
