| Summary | Description |
|---|---|
| Program Append | Adversaries may execute a program append to a PLC to update parts of an existing program. It may or may not require stopping the PLC which may allow it to continue running during transfer and reconfiguration without interruption to process control. Adversaries may leverage this approach to minimize downtime and evade detection. The ability to perform a program append to the PLC typically relies on access to a workstation with the vendor-specific PLC programming software installed. |
| Download All | Adversaries may execute a full program download to a PLC to overwrite the entire PLC program and configuration to deploy a new project or make major changes. This typically requires stopping the PLC and adversely impacting control processes. The ability to perform a full program download to the PLC typically relies on access to a workstation with the vendor-specific PLC programming software installed. |
| Online Edit | Adversaries may execute an online edit of a PLC to update parts of an existing program. It does not require stopping the PLC which allows it to continue running during transfer and reconfiguration without interruption to process control. Adversaries may leverage this approach to minimize downtime and evade detection. The ability to perform an online edit to the PLC typically relies on access to a workstation with the vendor-specific PLC programming software installed. |
