ASD ISM 1095 Proper labelling of wall outlet boxes
What it says
Wall outlet boxes denote the systems, cable identifiers and wall outlet box identifier.
Quoted as published. Everything else on this page is written by Control Stack.
What it means
In plain EnglishLabel wall outlet boxes with system, cable, and box identifiers for easy identification.
Labelling wall outlet boxes clearly with the system information and cable identifiers is crucial because it helps everyone know what is plugged into where. This can prevent accidental disconnections or errors during troubleshooting, which can lead to data loss or disruption of services.

Why it matters
Improperly labelled wall outlet boxes can cause mistaken disconnections, leading to service interruptions or data loss during maintenance or troubleshooting.
How to implement
The IT team should create a standard labelling system for all wall outlet boxes.
This involves using a consistent format, such as numbering systems or colour codes, to ensure clarity across all outlets.
Administrators or office managers should coordinate with technicians to perform a walkthrough of the premises.
During this, they should physically label each outlet according to the standard, ensuring all cables are matched with their respective identifiers.
Facilities management should keep a log of all labelled outlets.
This means maintaining a spreadsheet or a digital document listing each outlet with its identifiers, location, and the connected system.
IT staff should perform regular checks to ensure labels remain legible and accurate.
This involves visually inspecting each label and replacing faded or damaged ones promptly.
The procurement team should ensure any new cabling installations include an update to the labelling system.
They should work closely with contractors to ensure new outlets are labelled according to established standards immediately upon installation.
Keep it running
Periodically audit wall outlet box labels for system name, cable identifier and outlet ID; replace faded labels and update changes after moves/adds/changes.
Evidence and audit
- Check 1 of 5What an auditor asks for
Ask for
The outlet labelling procedure document: Request the guideline that outlines how wall outlet boxes are to be labelled within the organisation.
Look at
Specific steps and standard labelling formats.
Good evidence
Shows a clear, concise document outlining procedures and standards for labelling.
- Check 2 of 5What an auditor asks for
Ask for
A sample of labelled wall outlets: Request a demonstration of recently labelled wall outlet boxes in multiple areas.
Look at
The consistency and legibility of the labels.
Good evidence
Outcome is seeing uniform and easy-to-read labels across all outlets.
- Check 3 of 5What an auditor asks for
Ask for
A maintenance log of outlet labels: Request records showing recent inspections and any maintenance updates.
Look at
Entries detailing checks and replacements.
Good evidence
Shows a regular interval of inspections with documented fixes for any issues.
- Check 4 of 5What an auditor asks for
Ask for
To see documentation for any new outlet installations: Request records of new installs and their labelling.
Look at
Evidence that labelling was done immediately and correctly.
Good evidence
Result is having documented installs that align with the organisational standard.
- Check 5 of 5What an auditor asks for
Ask for
Any incident reports related to wall outlet identification: Request documentation showing past issues with outlet misidentification.
Look at
How they were resolved and whether labelling played a role.
Good evidence
Is a minimal or clear resolution in past incidents, indicating effective implementation of labelling standards.
Mappings
Closest match in ISO/IEC 27001: A.7.12, Secure cabling for power and data, which partially overlaps with this control.
ISO/IEC 27001: 1 mapping
This control partially overlaps A.7.12.
ISM-1095 requires wall outlet boxes to be labelled with the relevant system, cable identifiers and the wall outlet box identifier so that cabling endpoints can be physically identified and traced. This overlaps with ISO/IEC 27001:2022 Annex A 7.12 because accurate physical identification of outlets/cable terminations helps reduce misconnection and maintenance errors that can cause interference or damage, and it supports prompt, correct isolation of affected runs when physical tampering or faults are suspected. However, Annex A 7.12 is primarily about implementing protective measures (e.g. routing, shielding, segregation and other physical protections) against interception, interference or damage, whereas ISM-1095 focuses on labelling for traceability rather than providing protection by itself.
Mappings show how controls relate across frameworks. They do not imply full equivalence or certification.
