Description
Redundancy could be provided for both critical ICS devices and services, such as back-up devices or hot-standbys.
Techniques Addressed by Mitigation
| Name | Use |
|---|---|
| Denial of Control | Hot-standbys in diverse locations can ensure continued operations if the primarily system are compromised or unavailable. At the network layer, protocols such as the Parallel Redundancy Protocol can be used to simultaneously use redundant and diverse communication over a local network.1 |
| Denial of View | Hot-standbys in diverse locations can ensure continued operations if the primarily system are compromised or unavailable. At the network layer, protocols such as the Parallel Redundancy Protocol can be used to simultaneously use redundant and diverse communication over a local network.1 |
| Loss of Availability | Hot-standbys in diverse locations can ensure continued operations if the primarily system is compromised or unavailable. At the network layer, protocols such as the Parallel Redundancy Protocol can be used to simultaneously use redundant and diverse communication over a local network.1 |
