To simulate wireless attacks using OPNET that can include a numerous kinds of methods to aim wireless networks like eavesdropping, jamming, denial of service (DoS), man-in-the-middle (MITM), and spoofing attacks. Every kind of attack impacts the network performance and reliability within diverse ways that frequently using the wireless communication’s open nature. Here’s is a simple guide on how to simulate variety of wireless attacks in OPNET.
Steps to Simulate Wireless Attacks Projects in OPNET
- Set Up OPNET Environment
- In OPNET Modeler, make a new project then name it related like “Wireless Attack Simulation.”
- Set up the workspace making a wireless network including suitable nodes and settings such as Wi-Fi or cellular network types.
- Design Network Topology
- Configure a wireless network topology including:
- Access points (APs) or base stations: These devices offer wireless connectivity to client devices.
- Client devices: Laptops, smartphones, or IoT devices are denoting legitimate users.
- Attacker node: Located initiating wireless attacks versus client devices or the access point.
- Link the clients to the access points in a realistic range replicate the wireless network conditions.
- Configure Legitimate Network Traffic
- Configure typical network traffic among the clients and the access points. Describe normal applications utilizing Application Configuration:
- HTTP/HTTPS for web traffic.
- VoIP for real-time interaction.
- FTP or SMTP for file transfers and email.
- Allocate these applications to clients making the realistic wireless traffic, which can be impacted using the activities of attacker under Profile Configuration.
- Simulate Different Types of Wireless Attacks
- Eavesdropping Attack
- Objective: Observe the traffic inactively among clients and APs to accumulate data.
- Configuration:
- Locate the attacker node in the Wi-Fi range of client devices or the AP.
- In promiscuous mode (if supported), we can configure the attacker node to seize the packets that are transmitted across the wireless network.
- Packet headers, source and destination IP addresses, protocol types, and packet sizes to accumulate data.
- Observation:
- Monitor parameters like source-destination pairs, protocol distribution, and session timing examining the traffic patterns without distributing the network.
- Jamming Attack
- Objective: Interrupt the wireless interaction by flooding the channel with noise or interference.
- Configuration:
- Set up the attacker node to endlessly send the high-power, random packets or noise within the similar frequency band like the AP to trigger the interference.
- Maximize the transmission power and configure a high packet-sending rate to engage the wireless medium, to replicate a jamming impact.
- Observation:
- Observe the packet delivery rates and throughput at client devices. We will monitor the increased packet loss, delays, and connection drops.
- Denial of Service (DoS) Attack
- Objective: Overwhelm the access point or client devices including the excessive requests, to avoid legitimate access.
- Configuration:
- Configure the attacker transmitting repeated association requests or authentication requests to the access point consuming their resources.
- On the other hand, transmit high volumes of ICMP (ping) or UDP packets to targeted clients or APs.
- Observation:
- We can monitor the response times, packet loss, and connection stability. The AP or clients may try to reply to legitimate requests by reason of resource exhaustion.
- Man-in-the-Middle (MITM) Attack
- Objective: Potentially modify and interrupt the traffic among client devices and the AP.
- Configuration:
- Locate the attacker among the client devices and the AP to perform like a relay point.
- Set up the attacker imitating the AP such as by using the similar SSID and then we seize every packet those are swapped among clients and the AP.
- Change and forward packets if essential to replicate the traffic interception and manipulation.
- Observation:
- Observe data collected using the attacker to contain session information, protocol types, and data volume, monitoring the impacts on traffic.
- Spoofing Attack
- Objective: Imitate legitimate device interrupting network connections or steal data.
- Configuration:
- Configure the attacker node to spoof the MAC address or IP address of a legitimate client, to create the AP consider it is to interact with the original client.
- Transmit crafted packets along with the spoofed address influencing or to interrupt interaction.
- Observation:
- Monitor if legitimate client devices undergo connection drops or abnormal behavior because of disagrees with the spoofed address.
- Enable Data Collection for Performance Monitoring
- Set up data collection seizing the attack’s effect on the wireless network:
- Throughput: Estimate the network throughput measuring how much data is effectively sent in attack conditions.
- Packet Loss: We observe the packet loss and error rates that particularly in jamming and DoS attacks, which normally maximize the loss.
- Delay and Latency: Monitor delays and latency within data transmission that probably maximize in high-load or interference conditions.
- Connection Stability: Especially in jamming and spoofing attacks, we can monitor the connection drops and session re-establishment attempts.
- Run the Simulation
- In OPNET, we execute the simulation and monitor the impacts of the set up wireless attack. The attacker node will be performed their behavior, permitting to examine the influence over the wireless network performance and legitimate devices.
- Analyze Results
- Measure how each kind of wireless attack impacts the network performance utilizing OPNET’s analysis tools:
- Throughput and Bandwidth Utilization: Find out if the capacity of network managing legitimate traffic is minimized by reason of interference from the attack.
- Packet Loss and Errors: Analyse packet loss and error rates, in interaction estimating disruptions triggering by jamming or DoS attacks.
- Latency and Response Time: In network responses, confirm for maximized delay, to show that legitimate requests are being obstructed by the attack.
- Connection Stability: Estimate the frequency of dropped connections or session resets, to evoke compromised or intercepted interaction for MITM and spoofing attacks.
- Experiment with Different Attack Intensities
- Modify the attack intensities to replicate diverse parameters:
- Stealth Mode: Reduce the transmission power or minimize the packet-sending rate simulating a stealthier attack, which is harder to identify.
- Aggressive Mode: Maximize the intensity of the attack such as high packet rate for jamming or DoS monitoring how rapidly the network turn out to be unusable.
- Equate how diverse stages of attack intensity influence the network performance and detectability.
- Implement Countermeasures (Optional)
- Experiment the different countermeasures efficiency versus wireless attacks:
- Encryption (WPA2/WPA3): Set up WPA2 or WPA3 encryption at the wireless network that will be avoided attackers from capturing readable data for eavesdropping.
- Channel Hopping: We can set up access points modifying channels periodically to minimize interference for jamming attacks.
- Intrusion Detection Systems (IDS): Execute replicated IDS identifying unusual traffic patterns and alert administrators to likely DoS or MITM attacks.
- MAC Filtering: Utilize MAC filtering obstructing unauthorized devices from connecting to the network for spoofing attacks.
