  • What is Unauthorized Access ?
  • Packets
    IP packets are composed of a header and payload. The IPv4 packet header consists of:
    Version , Internet Header Length , Type of Service , Length , Identification ,TTL , Protocol , Header Checksum , Source IP and Destination IP.
  • Structure of Packets
  • Trace Back Methods
    • Reactive Tracing
    • Proactive Tracing
  • Trace Back Architecture Model
  • Trace Back System
    Monitoring Manager
  • Trace Back Algorithm
    Step 1: Start the Tracing process.
    Step 2: Receive the packet feature and pass it to packet search module.
    Step 3: Check Packet Information Area with packet feature received.
    Step 4: If any match found then let matched record as target record.
    Step 5: Compares the Address Information (i.e. MAC address) in target record with the address Information (i.e. MAC address &IP address) of the connected tracer stored in trace information.
    Step 6: If match found decide IP address and return to the monitoring manager as trace result.
    Step 7: Repeat step 3 to step 6 until source of the attack is detected.
    Step 8: Stop the Tracing Process.
  • Proposed Architecture for Trace back Process
    Reactive Tracing Hop by Hop Method
  • Process Flow
    Step 1: Sensors are deployed at each target network. When a sensor detects an attack, it creates data containing features of the attack packet and sends a tracing request to the monitoring manager deployed in its AMN.
    Step 2: The monitoring manager order the AMN’s tracer to trace the attack packet. The tracer identifies the adjacent node and returns the result to the monitoring manager.
    Step 3: Based on the result returned, the process described above continues until the tracer identifies the attack packet’s source.
    Step 4: If a tracing process goes beyond the AMN’s boundary, processing is handed over to the relevant monitoring manager that controls that AMN.
    Step 5: The monitoring managers in each AMN traces the packet in their AMN and sends the tracing result to the monitoring manager that initiated the traceback request.
    Step 6: The requester monitoring manager sends the final results to the sensor that requested the trace.
