ASD ISM 0236 Implement off-hook audio protection on telephones

IT team should install off-hook audio protection features: This involves configuring the phone systems to automatically mute the microphone when the handset is off the hook but not in active use.

Use the phone system's settings to activate this feature or consult the manual for guidance.

Procurement should ensure new phone systems include audio protection features: When buying new phones, specify models that include off-hook audio protection capabilities.

Check product specifications or ask vendors about these features before purchase.

Office managers should provide training sessions: Arrange short training sessions for staff on the importance of off-hook audio protection and how to use it.

Demonstrate how to check if off-hook protection is enabled on the phone and what actions to take if they suspect it's not.

System administrator should regularly test the feature: Conduct periodic checks on randomly selected phones to ensure the off-hook protection is active and functioning properly.

Document the test process and any issues found for follow-up.

Information security team should review policies: Review and update organisational policies to include requirements for off-hook audio protection in sensitive areas, ensuring staff understand their roles and responsibilities in maintaining phone security.
