Cloud & Telecom Security

Establishing Data Ownership is a fundamental component or building block of any Information Security Management System (ISMS).  The Data Owner is the single person ultimately responsible for their data.  They define policy, control who has access and may delegate some or all of their responsibility to Data Stewards.  The Data Custodians (typically IT) are the instrument of the Data Owner’s policies, enforce and manage policy compliance and help manage access rights and other IT controls according to the Data Owner’s requirements.
