Abstract
A method includes identifying, from among nodes within a multi-node system, a node that has a security setting satisfying a security setting criteria, booting the multi-node system with the identified node as the primary node, and operating the multi-node system using the security setting of the identified node. Accordingly, the method may provide dynamic selection of a primary node based upon the security setting criteria and the security settings of the nodes within the multi-node system. Optionally, the security setting of each node is stored in a trusted platform module. In non-limiting examples, the security setting criteria may be the highest security setting among all nodes within the multi-node system or a predetermined minimum security setting, such as a trusted execution technology setting.
