Deterrent

Deterrent

Definition(s)


Deterrent

Measure that discourages, complicates, or delays an adversary’s action or occurrence by instilling fear, doubt, or anxiety. Sample Usage: Robust countermeasures can serve as a deterrent to some adversaries, causing them to change, delay, or abandon their plans. Annotation:
  1. A deterrent reduces threat by decreasing the likelihood that an attack (or illegal entry, etc.) will be attempted.
  2. One form of deterrent is a prospective punitive action intended to discourage the adversary from acting (e.g., massive nuclear retaliation, Mutual Assured Destruction during the Cold War, or prison for conventional crimes). Another form of deterrent is a measure or set of measures that affects the adversary's confidence of success (e.g., fences, border patrols, checkpoints).
  3. A deterrent may cause an adversary to abandon plans to attempt an attack (or illegal entry, etc).
  4. A deterrent may cause the adversary to react by "threat shifting" in any of several domains: shift in time (delay); shift in target; shift in resources (additional resources); and/or a shift in plan or method of attack.
  5. Resilience, in terms of both critical economic systems and infrastructure and in societal resilience (e.g., the famed British ―stiff upper lip‖ of WWII, advance preparation for effective consequence reduction response operations, etc.), also has a potential deterrent value achieved when terrorist groups perceive that the strategic impact they seek through a particular attack or type of attack will not be achieved.

Effect that is an immediate result of an event, incident, or occurrence. Sample Usage: Property damage and loss of life were among the direct consequences resulting from the hurricane. Annotation:
  1. Direct consequences can include injuries, loss of life, on-site business interruption, immediate remediation costs, and damage to property and infrastructure as well as to the environment.
  2. The distinction between direct and indirect consequences is not always clear, but what matters in risk analysis is a) capturing the likely effects – be they designated as direct or indirect – that should be part of the analysis, b) clearly defining what is contained as part of direct consequences and what is part of indirect consequences, and c) being consistent across the entire analysis. Such consistency and clarity is important for comparability across scenarios and risk analyses.
