Organisation's data can only be processed on a predefined, trusted network, or by using a VPN service defined by the organisation.

For example, a coffee shop's Wi-Fi network is often either completely unencrypted or the password is easily accessible to everyone. In this case, the information sent online is vulnerable to spyware. A VPN connection encrypts information regardless of network settings.

The organization implements role-based access control with predefined access roles for the various protected assets that entitle access to the associated asset. Strictness of the access roles should reflect the security risks associated with the asset.

The following should be considered to support access management:

• how much information each user needs access to
• how widely the user should be able to edit data (read, write, delete, print, execute)
• whether other applications have access to the data
• whether the data can be segregated within the property so that sensitive data is less exposed

Security systems (e.g. firewall, malware protection) often have the ability to record a log of events. At regular intervals, make sure that a comprehensive log is accumulated and try to identify suspicious activity. The log is also useful in investigating disturbances or violations.
