MMS Protocol Technology Detection Scanner

MMS Protocol (IEC 61850-8-1) is widely used in industrial control systems (ICS) for automation and monitoring purposes. It is primarily implemented in power and utility networks to ensure efficient and reliable data exchange between devices. Vendors and utility providers use this protocol to facilitate seamless integration across various subsystems. Due to its critical role in infrastructure, its presence in systems must be identified for management and potential security assessments. Detection tools help maintain transparency in deployed assets, ensuring accurate inventory and compliance with regulations.

The scanner detects the implementation of MMS Protocol in network environments. By analyzing responses from devices communicating over TCP port 102, it identifies vendor details, model names, and revisions of devices using this protocol. This detection capability is crucial for organizations managing ICS systems to confirm the presence of specific technologies and vendors.

Technical details include sending identify requests over the MMS Protocol and analyzing the responses to extract vendor-specific information. This involves parsing raw hex data for fields such as vendor name, model name, and software or firmware revision. The scanner uses predefined request structures and extracts data directly from the protocol's responses to achieve accurate identification.

Exploiting the knowledge of the MMS Protocol's presence may enable attackers to tailor specific exploits or reconnaissance strategies. Malicious actors could identify critical infrastructure devices, exposing them to potential compromise or disruption. Detecting these systems helps mitigate risks by enhancing visibility and preparedness against such threats.
