Data Mapping
Data Mapping for Security and Privacy | Improve Decision Making
Phase I: Analysis & Scoping
Measures to undertake include having a solid understanding of why such an assessment is being undertaken, what departments, systems, and personnel are considered in scope, and more. Additional factors to consider for this initial phase:
- Identifying data groups (i.e., consumer data, federal data, internal employee data, corporate IP, etc.) and the relevant data types associated with each group.
- Beginning to conceptualize and understand the data flows for the data groups – specifically - how data is collected, used, shared & disclosed, stored, protected, retained, and disposed of.
- Assigning key roles, responsibilities, high-level deliverables, and overall expectation with both Centris consultants and your internal employees.
- Assessing information security/cybersecurity controls, along with third-party entities deemed in scope.
- Assessing regulatory compliance requirements (i.e., GDPR, CCPA, PIPEDA, federal agency compliance, etc.).
Phase II: Information Flow
Measures to undertake include conceptualizing, confirming - and then documenting – the information flow of all data groups and associated data types throughout the organization. When documenting the information flow, it’s critical to touch on the following elements: data items, format of data, location of data, access to data, and more. Additional factors to consider for this phase include the following:
- Collection – Where is data being collected from, in what manner, from what external entities, transmission protocols, etc?
- Used – What is the overall use and lawful purpose of the data being collected?
- Shared & Disclosed – Who is data being shared with – both internally and externally (i.e., third-parties), the specific data sets being shared, the rationale why?
- Storage and Protection – For data resident in an organization's information systems, how is it being stored and protected (i.e., encryption, etc.)?
- Retention – What established data retention periods are in place and the rationale for it?
- Disposal – How is data disposed of when no longer needed?
