To simulate a traffic analysis attack using OPNET that encompasses to make a network situation in which an attacker attempts to imply data regarding the network or user behavior by way of examining traffic patterns without intercepting directly or decrypting the content. Even though for cyberattack simulation, OPNET does not clearly offer components we can set up a situation to estimate the traffic analysis attacks by observing features and behaviours of traffic.
Below is a step-by-step instruction to simulate a traffic analysis attack project in OPNET:
Steps to Simulate Traffic Analysis Attack Projects in OPNET
- Set Up OPNET Environment
- We make a new project then name it properly like “Traffic Analysis Attack Simulation” in OPNET Modeler.
- According to the network type and scale such as LAN, WAN, or MANET, we can describe the workspace.
- Design Network Topology
- Make a topology including servers, routers, client devices (workstations, mobile devices), and insert one or more attacker nodes.
- Link devices along with suitable links such as wired or wireless, for traffic monitoring to make sure that the network environment deliberates a realistic configuration.
- Locate the attacker nodes within a place in which they can observe the traffic like on a distributed link or a segment where they can monitor the broadcast or multicast traffic.
- Configure Normal Application Traffic
- Describe diverse kinds of legitimate network traffic in Application Configuration:
- HTTP and HTTPS for web browsing.
- VoIP or Video Streaming for real-time interaction.
- FTP or Email for file transfer and email communication.
- Tailor these applications making traffic patterns, which deliberate typical network usage that the attacker will be examined to infer data.
- Set Up Traffic Patterns
- Allocate the applications to certain users or groups replicating typical network usage using Profile Configuration.
- Set up traffic characteristics that contain session intervals, start and end times, packet sizes, and data rates, simulating realistic behaviors through diverse times of day or user groups.
- Different traffic volumes by means of allocating diverse application profiles to distinct devices, to make sure that different and realistic traffic patterns.
- Configure Attacker Node for Passive Monitoring
- Set up the attacker node working within promiscuous mode (if available in OPNET) monitoring every traffic at the network segment.
- Locate the attacker node on a strategic network location like a switch with mirroring or on a gateway in which aggregated traffic can be monitored, if promiscuous mode is not supported.
- Enable Traffic Analysis Metrics
- Configure data collection at the attacker node observing parameters normally examined within traffic analysis attacks like:
- Packet Size Distribution: Monitor packet sizes implying kinds of applications being utilized such as VoIP packets probably small and frequent, whereas FTP packets may be large.
- Inter-Arrival Time: Estimate the time among packets identifying interaction patterns or bursts.
- Traffic Volume and Bandwidth Usage: Observe traffic volume detecting the periods of heavy usage, to expose peak usage times potentially or to detect the critical applications.
- Source and Destination Analysis: Monitor IP addresses and port numbers to know the interaction pairs and infer roles or services like according to the frequent incoming requests to detect the servers.
- Simulate Traffic Anomalies (Optional)
- To maximize traffic analysis simulation exactness, launch the anomalies such as modifications within traffic volume or new connections:
- Append new user connections or bursts of traffic replicating the behaviors, which the attacker may detect if suspicious.
- Modify usage patterns of specific applications like large data transfers over FTP replicating behaviors, which need to expose sensitive activities.
- Run the Simulation
- In OPNET, execute the simulation and monitor the network traffic and to see how the attacker node accumulate the information at traffic patterns.
- OPNET will be replicated the packet flows to prevent the attacker node monitoring data volume, packet size, and inter-arrival times.
- Analyze Results
- Analyse the data accumulated by the attacker node utilizing OPNET’s analysis tools:
- Traffic Patterns: Consider bandwidth usage over time detecting peak usage and infer significant network activities.
- Session Behavior: Monitor session begin and end times knowing the user activity programs.
- Communication Frequency: Examine common interaction pairs detecting sensitive information exchanges or critical nodes potentially.
- Packet Size and Timing: Detect certain applications depends on the constant packet sizes and timing intervals like VoIP or streaming applications.
- Evaluate Attack Effectiveness and Defense Mechanisms (Optional)
- If target contains to examine the defense mechanisms then deliberate to insert encryption or obfuscation techniques like:
- To execute the HTTPS rather than HTTP encoding data and cover packet contents, to create the analysis more complex.
- Complicate true packet sizes, for attackers to create it harder detecting application types by size alone to utilize the packet padding.
- Replicate the behaviour of attacker in these defense conditions and then equate the capacity to imply traffic data with and without encryption or padding.
