CP-11: ALTERNATE COMMUNICATIONS PROTOCOLS
NOT SELECTED FOR INDUSTRIAL CONTROL SYSTEMS
The information system provides the capability to employ [Assignment: organization-defined alternative communications protocols] in support of maintaining continuity of operations.
Contingency plans and the associated training and testing for those plans, incorporate an alternate communications protocol capability as part of increasing the resilience of organizational information systems. Alternate communications protocols include, for example, switching from Transmission Control Protocol/Internet Protocol (TCP/IP) Version 4 to TCP/IP Version 6. Switching communications protocols may affect software applications and therefore, the potential side effects of introducing alternate communications protocols are analyzed prior to implementation.
