Isolation
What is Isolation?
A security technique that separates systems, processes, or data from each other to prevent unauthorized access and contain the impact of breaches.

Frameworks that govern isolation
What the standards actually require on isolation
Requirements naming isolation across 6 standards, quoted from the control text.
Before anyone works on or near exposed conductors or parts that have been de-energized, a competent person must first have: positively identified the equipment and conductors, every energy source and the isolation points;
as-nzs-4836-2023-safe-working-on-or-near-low-voltage-and-extra-low-voltage-electrical-installations-and-equipment::3.1.1-3.1.2 · 3.1.1 and 3.1.2 Isolation principles and positive identification →Minimize the number of nonsecurity functions included within the isolation boundary containing security functions.
NIST800-SC-3(3) · SC-3(3) Security Function Isolation | Minimize Nonsecurity Functionality →Every pumpset (sprinkler, hydrant, hose reel, jockey or pressure-maintenance pump) is serviced to Section 3 in addition to the sprinkler (Section 2) and hydrant (Section 4) requirements.
as-1851-2012-routine-service-of-fire-protection-systems-and-equipment::3.2-3.3 · 3.1 to 3.3 Fire pumpsets: scope, inoperative precautions, isolation of start devices and frequency →Plant must be maintained and repaired to the manufacturer's specification, and if specifications are deficient the manufacturer should be contacted.

ISM-1605 · Hardening the isolation host operating system →Storage systems, and in particular backup and replication infrastructure, should be isolated physically and logically from general networks and from the systems whose data they protect, so that a compromise of production does not extend to the storage plane;
