Overview

Following the Swiss-Cheese model, defense design is based on protection layers (PL), as follows:

1. Trigger prevention - by avoiding the known triggers
2. Rebounding design - immediate resumption normal operation
3. Recovery design - alarming, troubleshooting and resumption
4. Escalation prevention - handling situations of failure of the operational defenses
5. Rescue design - in emergency
6. On-site testing - assuring that the blockages work as expected
7. Investigation design - assuring effective learning from incidence
