Section 14.131 Resilience and Recovery Testing

Question 1

Resilience Testing

Answer 1

Assess system’s ability to withstand and adapt to disruptive events

■ Ensures the system can recover from unforeseen incidents

■ Conducted through tabletop exercises, failover tests, simulations, and parallel
processing

■ Helps prepare for events like power loss, natural disasters, ransomware attacks, and data breaches

Question 2

Recovery Testing

Answer 2

Evaluates the system’s capacity to restore normal operation after a disruptive event

■ Involves executing planned recovery actions
■ Performed through failover tests, simulations, and parallel processing
■ Ensures that planned recovery procedures work effectively in a real-world scenario

Question 3

1 Tabletop Exercises

Answer 3

Scenario-based discussion among key stakeholders to assess and improve an organisations preparedness and response

■ No deployment of actual resources
■ Identifies gaps and seams in response plans
■ Promotes team-building among stakeholders
■ Low-cost and engaging for participants

Hypothetical disaster

Question 4

2 Failover Tests

Answer 4

Controlled experiment for transitioning from primary to backup components which ensures uninterrupted functionality during disasters

■ Requires more resources and time
■ Validates the effectiveness of disaster recovery plans
■ Can identify and rectify issues in the failover process

Question 5

3 Simulations

Answer 5

Computer-generated representation of a real-world scenario that allows for hands-on response actions in a virtual environment

■ Assesses incident responders and system administrators in real-time
■ Helps evaluate reactions and staff performance
■ Provides feedback for learning and improvement

Question 6

4 Parallel Processing

Answer 6

Replicates data and system processes onto a secondary system and runs primary and secondary systems concurrently

■ Tests reliability and stability of the secondary setup
■ Ensures no disruption to day-to-day operations
■ Assesses the system’s ability to handle multiple failure scenarios simultaneously

Question 7

Uses of Parallel Processing

Answer 7

Resilience Testing:

Tests the ability of the system to handle multiple failure scenarios

Recovery Testing:

Tests the efficiency of the system to recover from multiple points of failure
