To simulate the network probe attack has includes their scanning or probing network devices we collect the data about open ports such as active IP addresses and services running on the network. This investigation could be a precursor we further invasive attacks. In OPNET, replicating the network probe attack has includes the setting an attacker node we transfer various kinds of probe packets to target devices with the network and following on how well the network and target devices respond.
Here’s a step-by-step procedure we replicating a network probe attack in OPNET:
Steps to Simulate Network Probe Attack projects using OPNET
- Set Up OPNET Environment
- Open OPNET Modeler, builds a new project and label it based on our concentrate like as “Network Probe Attack Simulation.”
- Describe the workspace configuration of measured according on our intended network size and settings for samples as a LAN or WAN.
- Design Network Topology
- Configure a network topology that has contains they are:
- Servers and workstations representative the legitimate network devices.
- Routers or switches we replicate the network infrastructure.
- Attacker node we assign the network probe attack through scanning target devices for open ports and services.
- Connect this device utilized their appropriate connections such as wired or wireless to mitigate a real-world network.
- Configure Legitimate Network Traffic
- We build a consistent network activity for replication of legitimate traffic among clients and servers. Go to Application Configuration and configure the applications that replicate the general consumption:
- HTTP/HTTPS for web browsing.
- FTP for file transfers.
- VoIP for real-time applications.
- In Profile Configuration, we allocate this application for legitimate nodes it builds a background traffic that could be maintains for following on how well probing impacts of regular network operations.
- Set Up Attacker Node for Network Probing
- Improve an attacker node for the network and setting the operates various kinds of probes we demonstrated the data about network devices:
- IP Scan (Ping Sweep): setting the attacker node we transfer the ICMP Echo Requests such as ping requests we range an IP addresses we clarify the active hosts.
- Port Scanning: Configure the attacker to probe every target for open ports utilized the TCP SYN or UDP packets. This could be disclosing the open services on the target devices.
- Service Probing: Designed for further enhance the scans and set up the attacker we transfer the packets for specific ports such as 80 for HTTP, 443 for HTTPS, 22 for SSH for recognise the process services in software versions.
- Define Probe Parameters
- Configure the parameters metrices for every kinds of probe the attacker will transfer:
- Packet Size: configure the amount of ICMP or TCP packets utilized for probes. minimum packets are typical for stealthy scans.
- Scan Frequency: Describe the rate that probes are transfer. High-frequency scans are further aggressive and could be easy to finding as the while low-frequency scans are stealthier.
- Target IP Range: Stipulate the area of IP addresses the attacker would be scan. This can be complete the subnet or a specific subset of devices on the network.
- Port Range: It port scanning and setting a range of ports for sample 1-1024 or specific ports for common services.
- Enable Data Collection for Performance Metrics
- Configure the data collection for tracking the network behaviour and calculates the effect of the probe attack:
- Throughput: Calculate the bandwidth consumption for particularly near the target devices we demonstrate the probing traffic rise the network load.
- Packet Delay and Response Time: follow on response duration for follow the probe attack causes many latencies for in general performs.
- CPU Utilization: calculate the CPU load on routers and switches we classify the potential strain due to marinating the extreme of probe requests.
- ICMP, TCP, and UDP Traffic Count: Follow the volume of ICMP, TCP, and UDP packets for observe the attack’s impact of traffic composition.
- Run the Simulation
- Start the replication of follow the network probe attack. The attacker node can be scanning the network for transferring the packets in multiple IP addresses and ports.
- OPNET will replicate on how well the network responds for every probe as permitting the follow-on effect of both the target devices and complete network performance.
- Analyse Results
- Utilized the OPNET’s analysis tools to estimate the impact of the network probe attack:
- ICMP and TCP Traffic Analysis: Establish the volume of ICMP and TCP packets transfer through the attacker we allocate the intensity of the scan.
- Response Times and Packet Delay: Checked for high delays in legitimate network traffic that can be indicate interference from the probe traffic.
- Network and Device Load: Follow on CPU utilization on network devices such as routers and switches that may experience high load due to handling probe traffic.
- Detection of Active Hosts and Open Ports: Analyse the attacker’s probe responses for classify active devices and open ports, replicating the information a real attacker can be collected.
- Experiment with Different Attack Intensities
- Alter the probing intensity for follow on how well various levels of activity impact for network performance and detectability:
- Aggressive Scan: High the probe frequency and increase the target IP and port area for a rapid nevertheless easily finding scan.
- Stealth Scan: decrease the probe frequency and target fewer IPs or ports to mitigate a low-profile scan that is harder to detect.
- Associate the effect of aggressive versus stealthy scans for network performance, following many trade-offs among scan intensity and detectability.
- Implement Countermeasures (Optional)
- We demonstrate on how well defences impact of network probe for validate on potential countermeasures:
- Intrusion Detection System (IDS): setting an IDS which findings the high-frequency scanning activities, modify the network administrators for unusual activity.
- Rate Limiting: execute the rate limiting on routers we decrease the number of requests per IP or per second and avoiding the efficiency of rapid scanning.
- Firewall Rules: setting the firewall rules for block or drop traffic from suspected probing sources according on IP, frequency, or protocol.
