Extent of security shall depend on criticality of computerized system.

This will include definition of all settings and parameters.

4.7.4 Hardware design shall define hardware components i.e. 4.7.5 Network design specification shall include network diagram, security consideration and performance requirement.

Suitable method like passwords, keys, biometrics, restricted access to the area should be in place.
