Basis:

Different ICS mechanisms have different implications in different situations in terms of the consequences of protection failures.

Typical consequences identified include:

  • LOW: Wasted time and effort (inefficiency) and Losses reasonably covered by insurance (e.g., shrinkage, minor accidents and injuries).
  • MEDIUM: Substantial negative publicity, Acts viewed as gross negligence, Substantial enterprise value reduction, Serious injury, Limited environmental damage or societal harm.
  • HIGH: Loss of life, Serious environmental or societal damage, Enterprise Collapse, Other dire consequences

For example, a temperature control system might have LOW consequences in a small automated photographic developing facility, a MEDIUM consequence in a food production facility (where redundant tests identify a "bad batch"), and HIGH consequences in a chemical plant where its failure causes a major explosion.

Typically, consequences resulting from information protection failures are associated with a loss of integrity (I), availability (A), confidentiality (C), control over use (U), or loss of accountability (T) in an information system, with the ultimate result leading to real-world effects through the impact of the failures on the control system.


Processing rate or output quality is reduced {within / outside} of defined tolerance ranges: For example, water quality goes below required levels or tastes a bit off but remains within required levels.

Processing is stopped and has to be restarted and {no / some} equipment damage results: For example a faulty hazard conditions that has to be cleared to continue but lasts long enough to shut down the process.

Processing is stopped and cannot be restarted until {equipment / facility} is {repaired / replaced} resulting in {delay / loss / shutdown / etc.}: For example, too rapid opening or closing of a valve causing overpressure causing valve or pipe breakage.

Hazardous conditions arise during processing, producing undesired {internal / near-equipment / facility-wide / outside-of facility / regional / global} effects. [define area and effects]: For example leak of chemicals produced as a side effect of excess pressure in a processing element.

Competitive advantage is lost or reduced: For example, from leaked status or process details, corrupted content, etc.

Leaked status or process details leads to {internal / external} exploitation for {illegal activities / harm to plant or facility / harm to infrastructure / harm to enterprise}: For example, real-time data exploitable in marketplaces to gain financial advantage, details of when a particular event will happen or is hapenning, or alteration of targeting information in flight.

Limited loss of control: For example, inability to shut down a process using the normal method forcing physical presence.

Substantial loss of business or harm to brand results: For example tainted production output is detected at point of sale.

Conditions interfere with contracts or upset customers: For example, alterations to publicly accessible information or the data supporting it that indicates process failures of security inadequcies.

Confidential or proprietary data leaked: For example, production details indicating process problems are improperly available on en external portal.

Intellectual property like patent background and design data leaked: For example, access to the ICS environment might grant access to specifics of trade secret or pre-patent process.

Medical treatment, dose, or device controls that interact with humans fail (in various ways): For example, doses get changed due to cosmic rays altering memory.

Decision support mechanisms fail to provide proper assistance: For example, plant automation provides incorrect earning messages and displayed conditions.

Supervisory control and data acquisition (SCADA) systems fail to operate properly: For example, a maintenance change causes the SCADA to issue commands intended to damage the plant.

Programmable logic controllers (PLCs) fail to operate properly: For example a PLC stuck-at failure causes a valve to refuse to shut.

Distributed Control Systems (DCS) fail to {accurately depict sensory data / properly actuate}: For example, varying delays through switching infrastructure cause desynchronized data to controllers.

ICS {internal / external} communications mechanisms fail to operate properly: For example, noise in a serial line causes lost or corrupted protocol elements.

Critical infrastructure systems fail {causing ICS effects / as a result of ICS failures}: For example, power outages cause molten metal to cool to a solid.

Legally protected confidential medical, privacy, or other data inadequately protected in ICS environment: For example, maintenance access reveals confidential information to vendor during upgrades.

{Internal/External} information asks ICS to operate in an {undesired/unsafe} mode: For example an intentional atteration of recepie values produces bad batches.

Legal mandates inadequately carried out in the ICS environment: For example, apparent shrinkage of controlled substance inventory because of inadequate precision and accuracy in volume measurement system.

Legal {retention / disposition / holds} impact ICS {operations / historians}: For example, a legal hold causes an overrun in historian storage causing loss of more recent records.

Industry-specific regulations unable to be properly met or demonstrated: For example, unable to clear end-of-period transactions because control system improperly reports remaining inventory.

Contractually mandated controls unable to be properly met or demonstrated: For example, control system unable to maintain parameters to within tolerances.

Contractual limitations on {use / sharing / disposition} improperly fulfilled: For example, an authoated repository system improperly sends the wrong documents to a shredder.

Contract performance data improperly {provided / applied}: For example, usage rates of a limited numnber of use mechanism are incorrectly analyzed for replacement scheduling.

Government classified or restricted data improperly handled: For example, classified control system settings improperly displayed in unclassified closed circuit television system surveilling the area.

Controls with regard to {import / export / transport / some other requirement} not properly carried out: For example, mislabeling results in transport of dangerous goods in the wrong container type.

Required {reporting / tracking / accountability} mechanisms not properly functioning: For example inventory not properly updated to reflect actual use in production.

Controlled {substances / devices / artifacts} inadequately controlled: For example, pick and place picks the wrong pills for a shipment.

Personally identifying information not properly controlled: For example, misassignment of shippoing labels to boxes being shpped.

Medical information (test results, fees, providers, etc.) not properly controlled: For example, misassociation of results with patients.

ICS production output tainted in obvious ways: For example, water comes out of the plany brown instead of clear.

ICS production output tainted in non-obvious ways harming down-stream application: For example, steal processing produces inferior steal resulting in weaker structures in use.

HMI doesn't accurately reflect actual activities of the system under control: For example a replay of prior events is played instead of live data.

Sensor output doesn't accurately reflect actual phenomena being sensed: For example, a faulty sensor produces false readings.

System operates open loop for a period of time: For example, the control signals are disabled by a switching infrastructure outage.

Safety system cross-linked with control system: For example accidental connections between respective networks.

Safety system overwhelmed by control system: For example the synchroinzed use of multiple control points produces more force than the safety system can compensate for.

Assumptions about process inputs (e.g., materials, amounts, concentrations, etc.) don't match reality: For example, a heavier grade of oil is used than designed for, a different composition of sand and gravel is used in a cement mixer, soda pop in drinking fountains, etc.

Positive feedback modes occur in unanticipated ways during operation: For example, a specific conifiguration not well tested produces undamped feedback in a subsystem when controls are synchronized to physical parameters..

Process mechanisms (e.g., mechanical structures) get altered by control system exploitation: For example, power cycling to cause metal migration, bang bang commands to deform a container, inteiontal overheating to cause power lines to droop, etc.

Theft or unaccounted for removal of materials from control system elements: For example stealing gasoline from a pipeline or oil from a lubricaiton system.

Addition of materials to control system elements: For example addition of coloring to a water system, chemicals to a chemical processing plant, sugar to a gas tank.

Deceptions of sensors and/or actuators carried out against control systems: For example, mechanically holding a float at a level regardless of actual fluid present.

Simulations substituted for actual elements of control systems: For example, replacement of a portion of a water system with a computer that provides phoney sensor data to steal water.

Repeated cycling of power / other external supply and/or demand: For example switching on and off lighting systems in a large building.

Waveform attacks on external supply and/or demand: For example, systematic increases and decreases in voltage supplied by multiple power plants feeding a central switching station combined with changes in demand from large customers.

Social influence effects on user behavior effecting control system: By example high volumes of toilet flushes during half-time at a football game augmented by social media water tainting story asking al citizens to run their water for 15 minutes.
