OLF 110 : 2009

Provides the typical phases in a large project, but may also serve as a guideline for smaller modification projects with the difference being that many of the phases already may have information security measures implemented for the activities identified in this document. It is important for all project types on an existing installation to use the guideline in order not to compromise the information security of the installed systems or as a measure to improve existing design or practices. Applies to all ICT systems for Process Control, Safety and Support (PCSS) which are part of any production facility.
