To simulate Quench Attack using OPNET that is a kind of denial-of-service (DoS) attack, it obtains Internet Control Message Protocol (ICMP) Source Quench message’s benefit. Usually, ICMP Source Quench messages were utilized to indicate a sender to decelerate their transmission rate that supporting to handle the network congestion. An attacker transmits forged ICMP Source Quench messages to mislead a target device toward minimizing their network throughput, and efficiently throttling their performance in a quench attack.
While ICMP Source Quench messages are generally out-dated and frequently disregarding within modern networks, in OPNET to replicate a quench attack can support to demonstrate the fake ICMP control message’s effect at network performance.
We follow the below steps to simulate a quench attack using OPNET:
Steps to Simulate Quench Attack Projects in OPNET
- Set Up OPNET Environment
- We make a new project then name it something related such as “Quench Attack Simulation” in OPNET Modeler.
- Set up the network containing client devices, a target server, and network infrastructure such as routers. The attacker node will be replicated the quench attack.
- Design Network Topology
- Describe a network topology, which encompasses:
- Target server or device: The device whose throughput we need to influence like a web server or file server.
- Client devices: Legitimate users, which get into the target server, to replicate typical network traffic.
- Routers or switches: Network devices that enable the traffic among clients, the target, and the attacker.
- Attacker node: Set up to transmit forged ICMP Source Quench messages to the target device.
- Configure Legitimate Network Traffic
- Configure typical network traffic among client devices and for monitoring impacts of quench attack the target server making a baseline. Go to Application Configuration and describe applications like:
- HTTP or HTTPS for web-based traffic.
- FTP for file transfers.
- VoIP for real-time interaction.
- Allocate these applications to client devices, to replicate normal network usage utilizing Profile Configuration.
- Configure the Attacker Node for Quench Attack
- Set up the attacker node transmitting a continuous stream of forged ICMP Source Quench messages to the target server:
- Packet Type: Choose ICMP like the packet type including the subtype set to Source Quench.
- Spoofed Source IP: Spoof the source IP address of the ICMP packets creating them perform like if from a legitimate client or router they are arriving. For the target server, it can create it harder detecting the quench messages like a portion of an attack.
- Frequency and Timing: Set up the attacker node transmitting these ICMP Source Quench messages on a high frequency replicating an ongoing attempt to throttle the throughput of target.
- Define Attack Intensity and Timing
- Describe the attack metrics managing the frequency and time taken of the quench attack:
- Continuous Quench Flood: Utilize a high packet-sending rate including a continuous stream of ICMP Source Quench messages to the target server. It makes a constant throttling impact.
- Intermittent Quench Messages: Set up the attacker occasionally transmitting quench messages, to replicate a stealthier or lower-intensity attack.
- Program the attack to start after legitimate traffic is initiated, to permit monitoring the attack’s effect at the network performance equated to typical conditions.
- Enable Data Collection for Monitoring and Analysis
- Configure data collection at the target server, network devices, and client devices to observe the quench attack’s effect:
- Throughput Monitoring: Monitor throughput parameters at the target server identifying any reduction within transmission rate by reason of the quench messages.
- Packet Loss and Error Rates: Assess packet loss and error rates, in legitimate traffic monitoring if the quench messages trigger the interruptions.
- Network Latency: Observe latency among clients and the target server, since quench attacks can maximize delay within data transmission.
- ICMP Traffic Analysis: Particularly, we can monitor ICMP traffic to identify an unusual number of Source Quench messages that should show an attack.
- Run the Simulation
- In OPNET, execute the simulation to permit the attacker transmitting ICMP Source Quench messages whereas legitimate clients continue to communicate with the target server.
- Monitor the target server’s behavior and network performance in the quench attack’s impact, to observe any signs of throttled throughput or maximized latency.
- Analyze Results
- Measure the quench attack’s impact on network performance and resource utilization utilizing OPNET’s analysis tools:
- Throughput Reduction: Confirm if the throughput of target server is minimized like an outcome of processing the quench messages. If effective then server’s transmission rate to clients would reduce.
- Latency and Delay: For legitimate traffic, monitor any increase within delay or latency that probably influenced using the quench messages.
- ICMP Traffic Analysis: Consider ICMP traffic logs detecting the frequency and patterns of Source Quench messages, to discover if the attack is measurable via abnormal ICMP activity.
- Service Availability: Confirm if the service offered by the target server like web or FTP then it is impacted by the attack, especially if legitimate connections are slow down or throttled.
- Experiment with Different Attack Scenarios
- Modify the attack metrics to discover diverse situations:
- Higher Frequency of Quench Messages: Maximize the rate of ICMP Source Quench messages to experiment if a higher intensity minimizes the throughput.
- Distributed Quench Attack: Configure several attacker nodes, for each transmitting quench messages to the target to replicate a distributed quench attack.
- Varying Spoofed Sources: For each quench message creating it more complex for the target to acknowledge the messages like a portion of an attack utilizing diverse spoofed IP addresses.
- Implement Countermeasures (Optional)
- Experiment potential defenses versus the quench attack monitoring how they reduce the effect:
- ICMP Rate Limiting: Set up the target server or firewall restricting the rate of ICMP Source Quench messages it receives, from throttling throughput to avoid excessive messages.
- ICMP Filtering: Configure firewalls or routers to strain out ICMP Source Quench messages, since they are mostly out-dated and not generally utilized.
- Intrusion Detection System (IDS): Identifying abnormal ICMP traffic patterns like frequent Source Quench messages utilizing IDS from the similar or different IP addresses, for potential attacks to activate the alerts.
- Anomaly Detection: Execute the anomaly detection at the server to identify unusual drops within throughput caused by external messages, to support detect when quench attacks are happening.
