7.3.2.1 Security and privacy management functional component
The security and privacy management functional component is responsible for managing data provenance,
personal information in data and user access authority. This functional component aims to avoid data being
collected, stored by or disclosed to those who are not appropriate.
This functional component provides:
– the capability to manage identification and authorization so that only authenticated and authorized
users shall access the data;
– methods to protect the privacy of confidential data and sensitive data. For example, this function
supports data desensitization to protect the sensitive data.
NOTE 1 – Confidential data refers to provide for protection of data from unauthorized disclosure.
(see [b-ITU-T X.509]).
NOTE 2 – Sensitive data refers to personally identifiable information or other sensitive information
which is collected, stored, used, and finally destroyed or deleted.
