Security considerations for the implementation viewpoint

End-to-end security includes securing both IT and OT realms and their integration points.

Securing legacy systems includes securing legacy endpoints, systems, and data transmission in order to minimize the risks of an attack on the older systems. Each architectural pattern has its own unique sets of risks and areas to secure, including end points, information exchange, management and control, and data distribution and storage.

End-point security embeds security in the devices itself, enabling them to protect themselves while disconnected from any central security management systems. Information exchange security protects communication and data exchanges, ensuring that the data remains private and authentic.
