Definition

The definition of storage security has many facets, and some of the key requirements are:

• Storage (and the appropriate manipulation capabilities) should only be accessible and visible to users with the appropriate permissions

• Users should be notified if their data has been tampered with or altered either intentionally or unintentionally

• Malicious users should not be allowed to access or tamper with other people’s storage. If possible, the system should be able to catch malicious users.

• User’s data should be physically deleted at the appropriate time. That is, it should not be present past its intended life-time

• Tracking unauthorized copying or access control delegations is also an important security concern.
