5April 2007Copyright © 2007 ISA Charter - Framework Part 4 builds on the models from Part 1 Part 4 builds on the security program from Part 2 Assume both Parts 2 and 3 have been implemented by asset owners The entry point for is the allocation to Zones/Conduits and Target Security Level (SLTarget) However, include enough information from Part 1 re Zones/Conduits and Security Levels to provide the context for Part 4 Develop a mechanism to determine the individual SL for a product and the overall SL for a system Security Requirements for devices, subsystems and systems will be distinguished by SL Part 4 would meet SL at a point in time; Part 3 work processes (e.g. patch management) would maintain that SL Vendors are expected to document the security "out of the box" and the means to achieve the desired SL ISA Security Compliance Institute certifies products to a security level System or device must be tested by the vendor at its highest SL Acceptance Tests must be completed at the Target SL (Part 2) Asset Owner are expected to enable the security capabilities offered by the vendor for the desired SL
