Data privacy and security in cloud environments is an ongoing issue. Guidelines for customers to observe when undertaking a risk assessment for their use of cloud services include information on facilities, networks, systems, applications, and data. An emphasis is also placed on confidentiality, integrity and availability.
The most important issues in cloud usage are:
- security of access;
- data integrity;
- data retention; and
- certainty of availability of the service(s).
You need to know what will happen if the service goes offline, and what compensation may be offered for loss of service and/or data. It is even more important to know what will happen if the service provider goes out of business or into liquidation.
