BCD-29: Continuous Data Protection (CDP)
Automated mechanisms exist to implement Continuous Data Protection (CDP) to capture data changes as they occur, enabling granular data recovery to a specific point in time.
Control Question: Does the organization use automated mechanisms to implement Continuous Data Protection (CDP) to capture data changes as they occur, enabling granular data recovery to a specific point in time?
Capability Maturity Model
Level 0 — Not Performed
Practices are non-existent, based on the inability to demonstrate an implemented and operational capability. A reasonable person would conclude the control is not being performed.
Level 1 — Performed Informally
SCR-CMM Level 1 criteria definitions are not available for this control: ▪ A reasonable person would conclude this control requires a structured process. ▪ At this level of maturity, the "ad hoc" nature of performing a capability informally would indicate the intent of the control is not met due to a lack of consistency and formality.
Level 2 — Planned & Tracked
Business Continuity & Disaster Recovery (BCD) capabilities are requirements-driven, but are not standardized across the entity (e.g., local/regional level consistency). Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Policies and standards associated with BCD domain capabilities are formally documented and centrally-managed by the entity. ▪ Standardized Operating Procedures (SOP) associated with BCD domain capabilities are documented and maintained by process owners. ▪ IT and/or cybersecurity personnel work with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with BCD domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD). ▪ Business Continuity / Disaster Recovery (BC/DR)-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines). ▪ BC/DR may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel. ▪ Appropriate TAASD exist to conduct full, incremental and/or differential backups (e.g., tape/disk, hybrid cloud or direct-to-cloud). ▪ IT personnel configure business-critical Technology Assets, Applications and/or Services to transfer backup data to the alternate site(s) at a rate that is capable of meeting RTOs and RPOs. ▪ The backup methodology is sufficient to support RTOs and RPOs for critical business functions. ▪ IT personnel store backups in a secondary location, separate from the primary storage site (e.g., cloud-based storage). ▪ IT personnel perform a random sampling of backups is tested at least semi-annually to verify integrity and recoverability of backed up data. ▪ Backups for sensitive/regulated data are cryptographically protected (encrypted and integrity checked) to prevent the unauthorized disclosure and modification of backup information. ▪ IT personnel backup copies of business-critical software, licenses/keys and other security-related information to the alternate site.
Level 3 — Well Defined
Business Continuity & Disaster Recovery (BCD) capabilities are standardized across the entity for applicability to People, Processes, Technologies, Data and/or Facilities (PPTDF) to ensure consistency for Technology Assets, Applications, Services and/or Data (TAASD). Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Policies and standards associated with BCD domain capabilities are formally documented and centrally-managed by the entity's Governance, Risk & Compliance (GRC) team, or similar function. ▪ Standardized Operating Procedures (SOP) associated with BCD domain capabilities are well-documented and kept current by process owners. ▪ A Business Continuity & Disaster Recovery (BC/DR) team, or similar function, is appropriately staffed and supported to implement and maintain BCD domain capabilities. ▪ Technology is leveraged to enhance the efficiency and accuracy of BC/DR operations (e.g., BC/DR planning software, Disaster Recovery as a Service (DRaaS), Orchestration and Automation Tools). ▪ The entity's Governance, Risk & Compliance (GRC) team, or similar function, works with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with BCD domain capabilities to address Minimum Compliance Requirements (MCR) (e.g., applicable statutory, regulatory and/or contractual requirements) and Discretionary Security Requirements (DSR) (e.g., entity-required controls).
Level 4 — Quantitatively Controlled
Business Continuity & Disaster Recovery (BCD) capabilities, in addition to being standardized across the entity and centrally managed to ensure consistency across Technology Assets, Applications, Services and/or Data (TAASD), efforts are metrics driven to provide sufficient insight for decision makers to predict optimal performance, ensure continued operations and/or identify areas for improvement. Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Applicable SCR-CMM Level 3 (Well Defined) capabilities are implemented and operational. ▪ 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. ▪ Business and technical stakeholders are involved in reviewing and approving proposed changes to evolve capabilities.
Level 5 — Continuously Improving
Utilize SCR-CMM Level 3 or Level 4 (if available) criteria definitions: ▪ There are no defined Level 5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to operationalize this control. ▪ Level 5 capabilities should be considered “world-class” where the control builds on Level 4 capabilities, but are continuously improving through Artificial Intelligence (AI) and/or Machine Learning (ML) technologies. ▪ While it may be possible to develop responsive capabilities for this control through the use of AI and/or ML technologies, the criteria would be organization-specific to define.
Assessment Objectives
- BCD-29_A01 data requiring Continuous Data Protection (CDP) is identified and documented.
- BCD-29_A02 automated Continuous Data Protection (CDP) mechanisms capture data changes as they occur for the identified data.
- BCD-29_A03 the recovery window for which Continuous Data Protection (CDP) change history is retained is defined.
- BCD-29_A04 Continuous Data Protection (CDP) mechanisms enable recovery of the identified data to a specific point in time within the defined recovery window.
- BCD-29_A05 point-in-time recovery from Continuous Data Protection (CDP) is tested at a defined frequency and the results are documented.
- BCD-29_A06 Continuous Data Protection (CDP) operation is monitored and capture failures or gaps generate alerts that are investigated and resolved.
Evidence Requirements
- E-BCD-10 Data Backups
-
Documented evidence of a Continuity of Operations Plan (COOP)-related data backup scheme that demonstrates the methods of data backup (including protection measures) for all data types to ensure business continuity requirements.
Business Continuity
Technology Recommendations
Micro/Small
- Not typically required at this size; consider cloud file version history (e.g., OneDrive, Google Drive) for critical files
Small
- File and database version history (e.g., Microsoft 365 versioning, database point-in-time restore)
- Cloud provider point-in-time recovery (e.g., AWS RDS, Azure SQL)
Medium
- Point-in-time recovery for critical databases
- Hypervisor CDP or near-CDP replication (e.g., Veeam CDP, Azure Site Recovery)
Large
- Enterprise CDP platform (e.g., Zerto, Veeam CDP, Dell RecoverPoint)
- Database point-in-time recovery with transaction log shipping
Enterprise
- Enterprise CDP platform (e.g., Zerto, Dell RecoverPoint, Veeam CDP)
- Journal-based recovery integrated with the isolated recovery environment
- Automated recovery point validation
