DATA ASSESSMENT
SUMMARY
This component allows the auditor to identify what sensitive data exists for the
organization, where it is stored, and how it is transferred.
PURPOSE
Sensitive files are often stored across multiple devices with different levels of security. A
data assessment allows the auditor to recommend secure storage solutions which best
meet the organizations risk assessment and workflow needs. While the auditor has insight
on some of this based on the Network Access and Network Mapping work, cross-staff
understanding and agreement on what constitutes sensitive data will support later
organizational change.
An adversary who obtains a laptop, workstation, or backup drive will be able to read or
modify sensitive information on the device, even if that staff member has set a strong
account password. This applies to threats involving loss, theft, and confiscation, but also to
"checkpoint" scenarios in which they may only have access for a few minutes. Furthermore,
in the event of a burglary or office raid, an adversary could obtain all sensitive information
on the organization's devices, possibly even undetected.

GUIDING QUESTIONS
What are the most important data sets to keep available? Are there backups?
What are the most important data sets to keep private?
How does the organization currently determine who should have access to data?
Is there currently anyone who has access to data who should not?
Does the staff agree on what constitutes sensitive data?
What data does each staff member need to be able to access in order to do their job?
APPROACHES
Data Mapping Activity: Have staff identify where that data is currently (what
devices/physical locations), who has access (physical, login, permissions), and who
needs to have access to get the organizations work completed.
