To simulate an eavesdropping attack using OPNET, we need to include setting up a passive attacker node, which intersects or observes network traffic accumulating data without dynamically changing or inserting packets. Eavesdropping attacks normally aim unencrypted traffic, to permit an attacker, for further attacks monitoring interaction patterns, collect sensitive information, or examine traffic flows.
Given below is a step-by-step procedure to replicate an eavesdropping attack in OPNET:
Steps to Simulate Eavesdropping Attack in OPNET
- Set Up OPNET Environment
- To make a new project then name it based on the focus like “Eavesdropping Attack Simulation” in OPNET Modeler.
- Describe the workspace settings then select a proper scale such as LAN or WAN.
- Design Network Topology
- Configure a network topology, which comprises of:
- Servers and client devices such as workstations, laptops, mobile devices to denote the legitimate network users.
- For standard network connectivity, we can utilize Routers or switches.
- Locate Attacker node to observe the traffic flowing among legitimate devices.
- Link the devices along with proper links like wired Ethernet or wireless, making a realistic network environment.
- Configure Legitimate Network Traffic
- Configure typical application traffic mimicking normal network activity. Describe applications in Application Configuration:
- For web browsing to utilize HTTP for unencrypted traffic replicating vulnerabilities HTTP or HTTPS.
- FTP for file transfers.
- For email communication, we need to use Email protocols like SMTP, IMAP, or POP3.
- VoIP for real-time interaction if learning influences over latency-sensitive applications.
- Allocate these applications to client and server nodes using Profile Configuration, to make realistic traffic flows and to permit monitoring the eavesdropping’s effect on diverse traffic types.
- Position the Attacker Node for Optimal Monitoring
- In a position, locate the attacker node, which permits it monitoring network traffic without natively communicating with it:
- On the Same Subnet: Locate the attacker node at the similar LAN segment like the target devices to seize broadcast and unicast traffic.
- Near Key Network Devices: Position the attacker node close a router, switch, or network gateway observing more traffic since it traverses.
- Within Range for Wireless Networks: Place the attacker node in the wireless range of target devices intersecting unencrypted wireless traffic for Wi-Fi networks.
- Configure the Attacker Node for Passive Eavesdropping
- Configure the attacker node functioning within promiscuous mode (if supported in OPNET) that permits it to seize every network packet at the shared network segment, not only packets addressed to it.
- Set up the attacker node accumulate information on:
- Source and Destination IP Addresses: Monitor interaction pairs to relate the network relationships and detect crucial nodes.
- Protocol Types and Ports: We can observe the traffic types like HTTP, FTP, and VoIP, knowing the services engaged.
- Packet Sizes and Timing: Log packet sizes and timing intervals to imply potential application usage or dynamic sessions.
- Enable Data Collection for Analysis
- Describe the data collection metrics to accumulate insights at network traffic for the attacker node:
- Throughput and Traffic Volume: Monitor the number of information traverses the network detecting peak usage times and high-volume devices.
- Protocol Distribution: To seize statistics at protocol types such as HTTP, FTP, VoIP, and so on to imply application types and usage.
- Source-Destination Pair Analysis: Observe IP pairs detecting generally interacting devices that would show critical network relationships.
- Timing Patterns: Track inter-packet arrival times and session lengths that would expose the user activity patterns and application usage schedules.
- Run the Simulation
- In OPNET, execute the replication to permit the attacker node to inactively observe the network traffic even though other nodes generally interact.
- The attacker node will seize data at packet flows, to support examine the network features an eavesdropper might monitor.
- Analyze Results
- Consider the collected data using OPNET’s analysis tools by the attacker and estimate the potential insights are acquired:
- Traffic Patterns: Monitor the traffic volume among numerous devices and time periods detecting critical interaction periods and nodes.
- Protocol Usage: Examine the protocols’ distribution such as HTTP, FTP, and so on to know the kinds of services and applications engaged.
- Communication Relationships: Estimate the source-destination pairs to find out which devices often interaction to show significant roles or dependencies.
- Timing and Session Patterns: In packet exchanges, to study timing patterns to imply user behavior likes regular check-ins, periodic updates, or dynamic sessions.
- Experiment with Different Network Conditions
- Experiment how they impact the capability of attacker to replicate diverse condition, accumulating information:
- Increased Traffic Volume: Insert additional users or data-intensive applications to maximize the network activity and then monitor if it impacts the attacker’s ability to seize and examine traffic.
- Scheduled Events: Make a periodic or scheduled traffic like backup or update events, monitoring if the attacker can identify periodic patterns within network usage.
- Implement Security Measures (Optional)
- To experiment the countermeasures’ efficiency versus eavesdropping, set up security methods at the network:
- Encryption (HTTPS, SSH, VPN): Swap unencrypted protocols such as HTTP and FTP along with encrypted ones, like HTTPS, SSH, or a VPN. From accessing readable data, it will avoid the attacker even though permitting them to seize metadata such as packet size and timing.
- Network Segmentation: Restrict the visibility of attacker through the network utilizing VLANs or subnetting, to separate the sensitive traffic minimizing eavesdropping opportunities.
- Traffic Obfuscation: Launch packet padding or arbitrary delays to cover actual packet sizes and timing patterns, for the attacker to create it more difficulty to imply data.
