Whether discussing physical or logical access controls, organizations have for years applied the practice of the two-person rule to help secure IT assets. Using the two-person rule is an optional approach for organizations wanting to protect access to key data sets, or to restrict who may perform sensitive or high impact operations on a system.In many circumstances, however, more traditional IT security controls are likely appropriate. Using the two-person rule is most often reserved for restricting the most sensitive IT security operations performed within an organization. Whether and where a given organization could apply the two-person rule depends on its policies, architecture, processes, and requirements.
This Sun BluePrints cookbook describes how to use Solaris Role-Based Access Control (RBAC) in the Solaris 10 Operating System (Solaris OS) to enforce the two-person rule in IT security.
