|Name=Loss of Control
|Category=Impact
|Technical Description=Adversaries may seek to achieve a sustained loss of control or a runaway condition in which operators cannot issue any commands even if the malicious interference has subsided.[[CiteRef::Reference - Corero]][[CiteRef::Reference - SANS - 201510]][[CiteRef::Reference - RIoT]]

The German Federal Office for Information Security (BSI) reported a targeted attack on a steel mill in its 2014 IT Security Report.[[CiteRef::German Steel Mill - German Federal Office for Information Security - 2014]] These targeted attacks affected industrial operations and resulted in breakdowns of control system components and even entire installations. As a result of these breakdowns, massive impact resulted in damage and unsafe conditions from the uncontrolled shutdown of a blast furnace.

|Description=Provide operators with redundant, out-of-band communication to support monitoring and control of the operational processes, especially when recovering from a network outage [[CiteRef::reference - NIST SP 800-53]]. Out-of-band communication should utilize diverse systems and technologies to minimize common failure modes and vulnerabilities within the communications infrastructure. For example, wireless networks (e.g., 3G, 4G) can be used to provide diverse and redundant delivery of data.

|Description=Hot-standbys in diverse locations can ensure continued operations if the primarily system are compromised or unavailable. At the network layer, protocols such as the Parallel Redundancy Protocol can be used to simultaneously use redundant and diverse communication over a local network.[[CiteRef::mitigation - redundancy - 201302]]

|Description=Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise.  Maintain and exercise incident response plans [[CiteRef::mitigation - developing IR - 200910]], including the management of "gold-copy" back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.
