Environmental Support

Definitions:

  Any environmental factor for which the organization determines that it needs to continue to provide support in a contingency situation, even if in a degraded state. This could include factors such as power, air conditioning, humidity control, fire protection, lighting, etc. For example, while developing the contingency plan, the organization may determine that it is necessary to continue to ensure the appropriate temperature and humidity during a contingency situation so they would plan for the capacity to support that via supplemental/mobile air conditioning units, backup power, etc. and the associated procedures to ensure cutover operations. Such determinations are based on an assessment of risk, system categorization (impact level), and organizational risk tolerance.
