A0005: Intelligent Electronic Device (IED)

An Intelligent Electronic Device (IED) is a type of specialized field device that is designed to perform specific operational functions, frequently for protection, monitoring, or control within the electric sector. IEDs are typically used to both acquire telemetry and execute tailored control algorithms/actions based on customizable parameters/settings. An IED is usually implemented as a dedicated embedded device and supports various network automation protocols to communicate with RTUs and Control Servers.

Executive priority

A0005: Intelligent Electronic Device (IED) is an official MITRE ATT&CK ICS asset. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.

Technical view

Security teams should validate A0005: Intelligent Electronic Device (IED) by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Embedded), and available local telemetry before making detection or mitigation decisions.

Likely telemetry

Official ATT&CK relationships and object metadata

Detection direction

Validate whether A0005: Intelligent Electronic Device (IED) appears in your detection coverage and tabletop scenarios.
Use the object to align executive risk language with SOC, incident response, and detection engineering work.
Do not treat ATT&CK relationship context as attribution without corroborating evidence.

Mitigation priorities

Map the object to existing controls and identify missing telemetry or response ownership.
Prioritize mitigations that reduce exposure on the listed platforms and tactics.
Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.

Additional notes and limits

Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.

This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Generated from the cited source records. This long-tail analysis has not been individually reviewed by a named human.
