SC-29—Heterogeneity
>Control Description
Heterogeneity techniques include the use of different operating systems, virtualization techniques, and multiple sources of supply. Multiple sources of supply can improve component availability and reduce the impact of a supply chain cybersecurity compromise. In case of a supply chain cybersecurity compromise, an alternative source of supply will allow the enterprises to more rapidly switch to an alternative system/component that may not be affected by the compromise. Addtionally, heterogeneous components decrease the attack surface by limiting the impact to the subset of the infrastructure that is using vulnerable components.
