Critical Software or System Failure

Hazard in Cybersecurity & Technology Failure, on the established threats & hazards list

Impact
5432112345

Likelihood

Likelihood
2

Unlikely — Possible but infrequent — roughly once in 50 to 100 years (1–2% chance in any year).

Impact
4

Major — Severe effects — casualties possible, serious damage across a significant share of the jurisdiction, essential services disrupted for weeks, outside assistance needed.

Readiness
3

Moderate — The organization has a generally established capability to manage this threat or hazard, but identifiable gaps remain. The organization could likely perform many required actions, though effectiveness may vary depending on conditions, staffing, resources, or complexity.

The national record

FEMA’s National Risk Index doesn’t model Critical Software or System Failure. Your team fills it with local evidence, and Hazzard shows the gap rather than a zero.

The national record

What the federal data says about Critical Software or System Failure: nothing yet

No federal dataset scores Critical Software or System Failure or files declarations under it. That's common for threats and emerging hazards, and it's why a brief for Critical Software or System Failure is built from your own plans, exercises and records. Hazzard shows the gap instead of inventing a number.

In your plan

What a Critical Software or System Failure profile needs, and where each part comes from

A local hazard mitigation plan profiles each hazard the same way (44 CFR 201.6). Here is how Hazzard fills each part for Critical Software or System Failure.

  1. Location

    44 CFR 201.6(c)(2)(i)

    Your documents

    No national layer maps Critical Software or System Failure. We draw the geographic extent from your plans, studies and annexes, cited to the page.

  2. Extent

    44 CFR 201.6(c)(2)(i)

    Your documents

    The magnitude your plans use for Critical Software or System Failure (a scale, a depth, an acreage, a duration), read from your documents and cited, so the profile states the strength you plan for.

  3. Previous occurrences

    44 CFR 201.6(c)(2)(i)

    Your documents

    FEMA files no declaration type for Critical Software or System Failure. The history comes from your after-action reports, incident records and plans.

  4. Probability of future events

    44 CFR 201.6(c)(2)(i)

    Your team decides

    No national dataset gives a frequency for Critical Software or System Failure. Your team scores likelihood on your scale from the evidence we organize.

  5. Vulnerability and impacts

    44 CFR 201.6(c)(2)(ii)

    Your documents

    The Census population profile and HHS emPOWER counts for context; the consequences themselves come from your plans and exercises.

  6. The assessment itself

    Your team decides

    Likelihood, impact and readiness for Critical Software or System Failure are drafted with every source attached, and a person on your team accepts each one. Hazzard never records a score on its own.

How we can help

How we’d help you prepare for Critical Software or System Failure

  1. 1
