Which of the following is a security concern for DNP3?
A significant security concern for the Distributed Network Protocol 3 (DNP3) is that authentication is not allocated. The original specification of DNP3 did not include built-in authentication mechanisms, which makes it challenging to verify the authenticity of messages. This vulnerability can potentially be exploited for various attacks, including man-in-the-middle and unauthorized command injections, compromising the security of systems using this protocol.
The Distributed Network Protocol 3 (DNP3) is widely used in SCADA (Supervisory Control and Data Acquisition) systems for communication between control systems and remote devices. One significant security concern with DNP3 is the lack of built-in authentication mechanisms in the original protocol specification. This absence means that it is challenging to ensure that messages are genuinely from authorized sources, making the protocol vulnerable to various types of attacks, such as man-in-the-middle attacks and unauthorized command injections.
