DCH-24.1: Automated Tools to Support Information Location

There is no evidence of a capability to identify by data classification type to ensure adequate cybersecurity and data protection controls are in place to protect organizational information and individual data protection.

C|P-CMM1 is N/A, since a structured process is required to identify by data classification type to ensure adequate cybersecurity and data protection controls are in place to protect organizational information and individual data protection.

C|P-CMM2 is N/A, since a well-defined process is required to identify by data classification type to ensure adequate cybersecurity and data protection controls are in place to protect organizational information and individual data protection.

Data Classification & Handling (DCH) efforts are standardized across the organization and centrally managed, where technically feasible, to ensure consistency. CMM Level 3 control maturity would reasonably expect all, or at least most, the following criteria to exist: o Are expected to take the initiative to work with Data Protection Officers (DPOs) to ensure applicable statutory, regulatory and contractual obligations are properly addressed, including the storage, transmission and processing of sensitive/regulated data. o Maintain decentralized inventory logs of all sensitive/regulated media and update sensitive/regulated media inventories at least annually. o Create and maintain Data Flow Diagrams (DFDs) and network diagrams. o Document where sensitive/regulated data is stored, transmitted and processed in order to document data repositories and data flows. o Identify data classification types to ensure adequate cybersecurity and data protection controls are in place to protect organizational information and individual data protection. o Identify and document the location of information on which the information resides. o Restrict and govern the transfer of data to third-countries or international organizations. o Limit the disclosure of data to authorized parties. o Mark media in accordance with data protection requirements so that personnel are alerted to distribution limitations, handling caveats and applicable security requirements. o Prohibit “rogue instances” where unapproved third parties are engaged to store, process or transmit data, including budget reviews and firewall connection authorizations. o Protect and control digital and non-digital media during transport outside of controlled areas using appropriate security measures. o Govern the use of personal devices (e.g., Bring Your Own Device (BYOD)) as part of acceptable and unacceptable behaviors. o Dictate requirements for minimizing data collection to what is necessary for business purposes. o Dictate requirements for limiting the use of sensitive/regulated data in testing, training and research.

• A Governance, Risk & Compliance (GRC) function, or similar function, assists users in making information sharing decisions to ensure data is appropriately protected, regardless of where or how it is stored, processed and/ or transmitted.
• A data classification process exists to identify categories of data and specific protection requirements.
• A data retention process exists to protect archived data in accordance with applicable statutory, regulatory and contractual obligations.
• Data/process owners:
• A Data Protection Impact Assessment (DPIA) is used to help ensure the protection of sensitive/regulated data processed, stored or transmitted on internal or external systems, in order to implement cybersecurity and data protection controls in accordance with applicable statutory, regulatory and contractual obligations.
• Human Resources (HR), documents formal “rules of behavior” as an employment requirement that stipulates acceptable and unacceptable practices pertaining to sensitive/regulated data handling.
• Data Loss Prevention (DLP), or similar content filtering capabilities, blocks users from performing ad hoc file transfers through unapproved file transfer services (e.g., Box, Dropbox, Google Drive, etc.).
• Mobile Device Management (MDM) software is used to restrict and protect the data that resides on mobile devices.
• Administrative processes and technologies:

Data Classification & Handling (DCH) efforts are metrics driven and provide sufficient management insight (based on a quantitative understanding of process capabilities) to predict optimal performance, ensure continued operations and identify areas for improvement. In addition to CMM Level 3 criteria, CMM Level 4 control maturity would reasonably expect all, or at least most, the following criteria to exist:

• Metrics reporting includes quantitative analysis of Key Performance Indicators (KPIs).
• Metrics reporting includes quantitative analysis of Key Risk Indicators (KRIs).
• Scope of metrics, KPIs and KRIs covers organization-wide cybersecurity and data protection controls, including functions performed by third-parties.
• Organizational leadership maintains a formal process to objectively review and respond to metrics, KPIs and KRIs (e.g., monthly or quarterly review).
• Based on metrics analysis, process improvement recommendations are submitted for review and are handled in accordance with change control processes.
• Both business and technical stakeholders are involved in reviewing and approving proposed changes.

Data Classification & Handling (DCH) efforts are “world-class” capabilities that leverage predictive analysis (e.g., machine learning, AI, etc.). In addition to CMM Level 4 criteria, CMM Level 5 control maturity would reasonably expect all, or at least most, the following criteria to exist:

• Stakeholders make time-sensitive decisions to support operational efficiency, which may include automated remediation actions.
• Based on predictive analysis, process improvements are implemented according to “continuous improvement” practices that affect process changes.
