ID.AM-5.1: The organization’s resources (hardware, devices, data, time, personnel, information, and software) shall be prioritized based on their classification, criticality, and business value.
Determine organization’s resources (e.g., hardware, devices, data, time, personnel, information, and software):
oWhat would happen to my business if these resources were made public, damaged, lost…?
oWhat would happen to my business when the integrity of resources is no longer guaranteed?
oWhat would happen to my business if I/my customers couldn’t access these resources? And rank these resources based on their classification, criticality, and business value.
Resources should include enterprise assets.
Create a classification for sensitive information by first determining categories, e.g.
o Public - freely accessible to all, even externally
o Internal - accessible only to members of your organization
o Confidential - accessible only to those whose duties require access.
Communicate these categories and identify what types of data fall into these categories (HR data, financial data, legal data, personal data, etc.).
Consider the use of the Traffic Light Protocol (TLP).
Data classification should apply to the three aspects: C-I-A.
Consider implementing an automated tool, such as a host-based Data Loss Prevention (DLP) tool to identify all sensitive data stored, processed, or transmitted through enterprise assets, including those located onsite or at a remote service provider.
