SC-36 Distributed Processing and Storage
Control
Distribute the following processing and storage components across multiple [Selection: physical locations; logical domains]: [Assignement: organization-defined processing and storage components].
Discussion
Distributing processing and storage across multiple physical locations or logical domains provides a degree of redundancy or overlap for organizations. The redundancy and overlap increase the work factor of adversaries to adversely impact organizational operations, assets, and individuals. The use of distributed processing and storage does not assume a single primary processing or storage location. Therefore, it allows for parallel processing and storage.
Assessment Objective
- [Assignement: processing components] are distributed across [Selection: physical locations; logical domains];
- [Assignement: storage components] are distributed across [Selection: physical locations; logical domains].
Assessment Method
Examine
System and communications protection policy
contingency planning policy and procedures
contingency plan
system design documentation
system configuration settings and associated documentation
system architecture
list of system physical locations (or environments) with distributed processing and storage
system facility diagrams
processing site agreements
storage site agreements
system security plan
other relevant documents or records
Interview
System/network administrators
organizational personnel with information security responsibilities
organizational personnel installing, configuring, and/or maintaining the system
organizational personnel with contingency planning and plan implementation responsibilities
system developers/integrators

SC-36(01) Polling Techniques
|
Control
- Employ polling techniques to identify potential faults, errors, or compromises to the following processing and storage components: [Assignement: distributed processing and storage components] ; and
- Take the following actions in response to identified faults, errors, or compromises: [Assignement: actions].
Discussion
Distributed processing and/or storage may be used to reduce opportunities for adversaries to compromise the confidentiality, integrity, or availability of organizational information and systems. However, the distribution of processing and storage components does not prevent adversaries from compromising one or more of the components. Polling compares the processing results and/or storage content from the distributed components and subsequently votes on the outcomes. Polling identifies potential faults, compromises, or errors in the distributed processing and storage components.
Assessment Objective
- polling techniques are employed to identify potential faults, errors, or compromises to [Assignement: distributed processing and storage components];
- [Assignement: actions] are taken in response to identified faults, errors, or compromise.
Assessment Method
Examine
System and communications protection policy
system design documentation
system configuration settings and associated documentation
system architecture
list of distributed processing and storage components subject to polling
system polling techniques and associated documentation or records
system audit records
system security plan
other relevant documents or records

SC-36(02) Synchronization
|
Control
Synchronize the following duplicate systems or system components: [Assignement: duplicate systems or system components].
Discussion
[SC-36](#sc-36) and [CP-9(6)](#cp-9.6) require the duplication of systems or system components in distributed locations. The synchronization of duplicated and redundant services and data helps to ensure that information contained in the distributed locations can be used in the mission or business functions of organizations, as needed.
Assessment Objective
[Assignement: duplicate systems or system components] are synchronized.
Assessment Method
