A0003: Programmable Logic Controller (PLC)
A Programmable Logic Controller (PLC) is an embedded programmable control device. PLCs typically utilize a modular architecture with separate modules used to support its processing capabilities, communication mediums, and I/O interfaces. PLCs allow for the deployment of customized programs/logic to control or monitor an operational process. This logic is defined using industry specific programming languages, such as IEC 61131 CitationIEC February 2013, which define the set of tasks and program organizational units (POUs) included in the device’s programs. PLCs also typically have distinct operating modes (e.g., Remote, Run, Program, Stop) which are used to determine when the device can be programmed or whether it should execute the custom logic.

Executive priority
A0003: Programmable Logic Controller (PLC) 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 A0003: Programmable Logic Controller (PLC) 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 A0003: Programmable Logic Controller (PLC) 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.
