DCS-14 Environmental Systems
Environmental control systems in the datacenter are installed and kept up so that temperature and humidity are monitored, held within ranges accepted by the industry, and tested to show they keep working.
Source: CSA CCM v4.1, DCS-14. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open CSA CCM v4.1 in the compliance library.
Version 4.1 adds 11 controls (among them API security, log sanitisation and a service bill of materials) and renumbers several domains. CSA accepts v4.0.x during its transition; if your STAR assessment is still on v4.0.1, check the numbering against it.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Alerts configured but routed to an unmonitored mailbox
- Sensors not calibrated
- Testing limited to vendor maintenance visits with no effectiveness check
