ASD ISM 2007 Authorised medical device register for SECRET and TOP SECRET areas

What it says

An authorised medical device register for SECRET and TOP SECRET areas is developed, implemented, maintained and regularly verified.

Quoted as published. Everything else on this page is written by Control Stack.

What it means

In plain English

Keep, maintain and regularly check an approved list of medical devices allowed into SECRET and TOP SECRET areas.

Some areas in your organisation hold information classified as SECRET or TOP SECRET (the two highest levels of government classification). This control says you must create and keep an official list (a register) of every medical device that is allowed into those areas, such as a pacemaker, insulin pump, hearing aid or other personal medical item. Many of these devices contain wireless transmitters, microphones or memory, so an unapproved one could secretly record or leak sensitive information. The register has to be set up, put into use, kept up to date, and checked on a regular basis to make sure it stays accurate.

Why it matters

An unrecorded medical device with a hidden microphone, transmitter or memory could leak SECRET or TOP SECRET information, causing a serious national security breach.

How to implement

  1. The security manager creates a single register that records each approved medical device, the person who relies on it, the SECRET or TOP SECRET area it is permitted in, and the date it was authorised.

  2. The person needing a medical device in a classified area submits a written request, and a delegated approver checks the device's wireless, recording and storage features before adding it to the register.

  3. The facility security officer puts the register into active use by checking devices against it at entry points to SECRET and TOP SECRET areas before anyone is allowed in.

  4. The register owner keeps the list current by adding new devices, removing devices for people who have left or changed roles, and updating entries whenever a device is replaced or upgraded.

  5. The security team schedules a regular verification (for example every quarter) where they reconcile the register against people actually working in those areas and confirm each listed device is still genuinely required.

Keep it running

Review the register on a set schedule and whenever staff or devices change, so it always reflects exactly who is permitted to bring which device into classified areas.

Evidence and audit

  1. Check 1 of 5What an auditor asks for

    Ask for

    to see the authorised medical device register itself.

    Look at

    whether it covers SECRET and TOP SECRET areas specifically and lists each device with its owner and authorisation date.

    Good evidence

    is a single controlled document that is complete and clearly owned.

  2. Check 2 of 5What an auditor asks for

    Ask for

    who has authority to approve a medical device for entry into these areas.

    Look at

    a named role and a documented approval step.

    Good evidence

    shows approvals are made by a delegated officer after assessing the device's risk features.

  3. Check 3 of 5What an auditor asks for

    Ask for

    how the register is used at the point of entry.

    Look at

    access procedures or guard instructions for classified areas.

    Good evidence

    shows staff actually check devices against the register before granting access.

  4. Check 4 of 5What an auditor asks for

    Ask for

    how the register is kept up to date.

    Look at

    recent entries showing additions and removals when people or devices change.

    Good evidence

    shows the list is living, not a one-off document created years ago.

  5. Check 5 of 5What an auditor asks for

    Ask for

    evidence of the regular verification activity.

    Look at

    dated reconciliation records, sign-offs or review notes.

    Good evidence

    shows scheduled checks confirming every listed device is still authorised and required.
