Feel free to use any real example from your work or experience.

A :

 Protecting the Critical National through Use of Separation No single separation approach is adequate to utterly shield the fundamental countrywide infrastructure networks. A combination of sensible separation security measures, working together, is required to supply a strong defences-in-depth protection. These realistic separation protection measures are as follows:

• Implement real-time danger protection.

• Segment and defend imperative national infrastructure belongings from interconnected networks.

• Control user access and network activities.

• Protect data about indispensable national infrastructure property from data leakage.

• Implement robust protection without jeopardizing availability, integrity, and reliability requirements.

An Agenda for Action in Using Separation to Protect the Critical National Infrastructure

When finishing the Use of Separation to Protect the Critical National Infrastructure Checklist, the IT administrator need to adhere to the provisional listing of moves for making ready for contingencies in the tournament that separation fails. The order is now not significant; however, these are the activities for which the research would prefer to pro-vide a precise description of procedures, review, and assessment for case of use and admissibility.

1. Implement real-time threat protection.

2. Separate and shield indispensable property from interconnected networks by taking the following actions:

a. Control port access based totally on a wonderful safety model.

b. Operate at gigabit pace and, therefore, do no longer intervene with manipulate system availability and integrity standards.

c. Include unique competencies designed for control systems.

3. Provide a suitable intrusion prevention safety solution through taking the following actions:
