ABSTRACT
This chapter describes a DEOS runtime environment (D-RE) for realizing the DEOS process and its architecture. The DEOS process and architecture require the following fi ve functions: monitoring, reconfiguration, scripting, recording, and security, which are described in Section 6.1. It is necessary to adapt or customize a D-RE to a target system according to its dependability requirements (and functional requirements) as agreed upon by the stakeholders. Several D-RE customization options and examples are discussed in Section 6.2. Two cases of the implementation of the D-Visors and D-System Monitors are described in Section 6.3. Finally, security mechanisms introduced into the D-RE is described in Section 6.4.
