Common Security Threats

In today’s interconnected world, Ethernet applications are susceptible to a multitude of external security threats:

  • Eavesdropping
    Interception of data being transmitted over the network by an unknown party.
  • Man in the Middle Attacks
    Insertion into the communication between two devices, potentially altering or stealing data.
  • Replay Attacks
    The capture and retransmission of data packets to create unauthorized effects.
  • Unauthorized Access
    Devices without proper credentials accessing the network, potentially gaining sensitive information.
