A cybersecurity analyst at a financial institution is evaluating the incident response plan to ensure the organization's resilience to a cyber-attack. Which of the following actions is crucial in the preparation phase to minimize the impact and ensure efficient recovery from an incident?
Periodically reviewing and updating all security tools to their latest versions.
Encrypting all sensitive data within the organization's network to prevent unauthorized access.
Developing proprietary security standards rather than following established frameworks like ISO/IEC 27001.
Conducting tabletop exercises to simulate a cyber-attack and assess the response plan.
Conducting tabletop exercises is crucial in the preparation phase because it allows the incident response team to simulate a cyber-attack scenario in a low-risk environment. This helps in identifying potential weaknesses in the incident response plan and improves the readiness of the team. Periodically reviewing and updating tools ensures they are effective and operational, but this does not directly simulate an incident. Encrypting sensitive data, while it is a good security practice, is not specifically a preparatory action for incident response. Developing proprietary security standards may not align with industry best practices and does not ensure efficient recovery from an incident.
