1. CNES security development process

2. 2 Basic rules High level principles for ISS activities on projects are: ■Decisions dealing with security risks must be approved on relevant functional/hierarchical level. ■For each project, ISS must be integrated in the project management. ■Each project must integrate CNES security requirements. ■CNES ISS authorities (independent of project team) must be involved in each key event of the project. ■Security requirements must be function of functional sensitivity and security risks.

3. 3 ISS approach 1/6 ■ISS approach for project development must be integrated in the global approach of the project. ■The following slides describe the main stages (V cycle) of a project and, for each of them, what are the relevant security items. ■Two security activities are dealt with:  security of target IS to be developed,  security of development environment.
