equirement is “all health-related information that is covered by HIPAA regulations mustbe kept confidential to health workers and patients.”Service. Service requirements establish the resilience needs of a service in pursuit of itsmission. But because the capability of a service to meet its mission is directly related tothe resilience of the assets that support the service, service requirements must reflectand be congruent with the operational resilience requirements of supporting assets.Service requirements tend to concentrate on the service’s availability and recoverability,but these quality attributes can be directly affected by failure to meet the confidentiality,integrity, and availability requirements of people, information, technology, and facilities.Asset. Asset-specific requirements are set by the owners of the asset and are intendedto establish the needs for protecting and sustaining an asset with respect to its role insupporting mission assurance of a service. In practice, asset-specific resiliencerequirements generally reflect the security objectives of confidentiality and integrity andthe continuity requirement of availability. It must be considered that assets also mayhave conflicting requirements, particularly where they are deployed in supporting morethan one service (e.g., a network server may support more than service). This conflictmust be resolved to ensure that all services that are dependent on the asset areprovided the necessary level of resilience to meet their mission.The applicability of a specific type of resilience requirement varies depending on the assettype, as shown in Table 1.Table 1: Extension of resilience requirements to all types of resilience assetsResilienceRequirementAsset TypePeople Information Technology FacilitiesConfidentiality -- x -- --Integrity -- x x xAvailability x x x xThere are many ways in which an organization can elicit resilience requirements. Strategicplanning efforts may establish enterprise-level requirements, as would direct interviewing ofvital organizational managers. Service-level requirements may be established by owners ofthe service (e.g., an organizational unit or a line of business). Asset-level requirements maybe established through regular security risk assessment and business impact analysisactivities and through directly interviewing the owners of the assets, who understand theirimportance to services and are responsible for their productivity and resilience.All resilience requirements must be analyzed for conflicts and interdependencies and mustbe validated against and support the accomplishment of enterprise-level organizationaldrivers (goals, objectives, and critical success factors). Otherwise, the protection andcontinuity strategies developed and implemented for assets and services will not align withwhat the organization needs to accomplish in order to remain viable.The development of resilience requirements typically includes the following activities:identifying organizational drivers and preparing these work products so that they can beused as the foundation for setting resilience requirementsdeveloping and communicating enterprise-level requirementsdeveloping and communicating service and asset-level requirements172 | CMU/SEI-2010-TR-012
egularly analyzing the requirements to ensure alignment with current organizationaldrivers, to identify conflict between enterprise and asset-level requirements, and tosatisfy operational constraintsvalidating the requirements against organizational drivers and operational constraintsThe Resilience Requirements Development process area has three specific goals:1. The Identify Enterprise Requirements goal addresses the development of enterpriselevelrequirements that potentially affect all services and assets.2. The Develop Service Requirements goal addresses the development of service-levelrequirements through the identification of asset requirements and the assignment ofenterprise requirements to services.3. The Analyze and Validate Requirements goal addresses the analysis of service-levelrequirements to ensure that they support strategic drivers and the resolution of conflictingrequirements.The goals of the Resilience Requirements Development process area are supported andmanaged long term by achievement of the goals in the Resilience RequirementsManagement process area.Related Process AreasThe identification of high-value assets and the assignment of resilience requirements toassets and services are performed in the Asset Definition and Management process area.The identification of high-value services is performed in the Enterprise Focus process area.The identification and prioritization of risks to high-value services and supporting assets isperformed in the Risk Management process area.Resilience requirements are managed in the Resilience Requirements Management processarea.Summary of Specific Goals and PracticesGoalsRRD:SG1 Identify Enterprise RequirementsRRD:SG2 Develop Service RequirementsRRD:SG3 Analyze and Validate RequirementsPracticesRRD:SG1.SP1 Establish Enterprise Resilience RequirementsRRD:SG2.SP1 Establish Asset Resilience RequirementsRRD:SG2.SP2 Assign Enterprise Resilience Requirements toServicesRRD:SG3.SP1 Establish a Definition of Required FunctionalityRRD:SG3.SP2 Analyze Resilience RequirementsRRD:SG3.SP3 Validate Resilience Requirements173 | CMU/SEI-2010-TR-012
