**Control**

  

Off-site assets should be protected. **Purpose**

  

To prevent loss, damage, theft or compromise of off-site devices and interruption to the organization’s operations.

  

**Guidance**

  

Any device used outside the organization’s premises which stores or processes information (e.g. mobile device), including devices owned by the organization and devices owned privately and used on behalf of the organization \[bring your own device (BYOD)\] needs protection. The use of these devices should be authorized by management.

  

The following guidelines should be considered for the protection of devices which store or process information outside the organization’s premises:

  

a\) not leaving equipment and storage media taken off premises unattended in public and unsecured places;

  

b\) observing manufacturers’ instructions for protecting equipment at all times (e.g. protection against exposure to strong electromagnetic fields, water, heat, humidity, dust);

  

c\) when off-premises equipment is transferred among different individuals or interested parties, maintaining a log that defines the chain of custody for the equipment including at least names and organizations of those who are responsible for the equipment. Information that does not need to be transferred with the asset should be securely deleted before the transfer;

  

d\) where necessary and practical, requiring authorization for equipment and media to be removed from the organization’s premises and keeping a record of such removals in order to maintain an audit trail (see [5.14](a-5.14-Information-transfer.md));

  

e\) protecting against viewing information on a device (e.g. mobile or laptop) on public transport, and the risks associated with shoulder surfing;

  

f\) implementing location tracking and ability for remote wiping of devices.

  

Permanent installation of equipment outside the organization’s premises \[such as antennas and automated teller machines (ATMs)\] can be subject to higher risk of damage, theft or eavesdropping. These risks can vary considerably between locations and should be taken into account in determining the most appropriate measures. The following guidelines should be considered when siting this equipment outside of the organization’s premises:

  

a\) physical security monitoring (see [7.4](a-7.4-Physical-security-monitoring.md));

  

b\) protecting against physical and environmental threats (see [7.5](a-7.5-Protecting-against-physical-and-environmental-threats.md));

  

c\) physical access and tamper proofing controls;

  

d\) logical access controls.
