# safety (security)

Distance from a wall, bought by narrowing the range of parameters permitted.

- Computed level: L15 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: safety

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [narrow](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-narrow.spatial), [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [buy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-buy.economic), [range](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-range.spatial)

**Through:** Maintenance narrows the permitted parameter range, buying distance from the wall by keeping conditions within a tighter window.

**Novel properties:**
- acquired buffer zone
- costly stability
- constrained resilience

## Examples
- The 2021 Colonial Pipeline ransomware attack forced a 5-day shutdown despite backup protocols, exposing critical infrastructure fragility. *(engineering)*
- Singapore maintains strict public housing policies, limiting foreign ownership to preserve social stability and control urban density. *(institutions)*
- The International Space Station orbits at 400 km altitude, a carefully maintained range to avoid atmospheric drag and debris. *(physics)*
