A. Eradication

B. Recovery

C. Containment

Legacy medical equipment, which contains sensitive data, cannot be patched. Which of the following is the best solution to improve the equipment\’s security posture?

A. Move the legacy systems behind a WAR

B. Implement an air gap for the legacy systems.

C. Place the legacy systems in the perimeter network.

D. Implement a VPN between the legacy systems and the local network.

Correct Answer: B

Analysis and explanation

Implementing an air gap for the legacy systems is the best solution to improve their security posture. An air gap is a physical separation of a system or network from any other system or network that may pose a threat.

An air gap can prevent any unauthorized access or data transfer between the isolated system or network and the external environment.

Implementing an air gap for legacy systems can help protect them from being exploited by attackers who may take advantage of their unpatched vulnerabilities.

A. Tabletop scenarios

B. Capture the flag

C. Red team vs. blue team

D. Unknown-environment penetration test

Correct Answer: A

Analysis and explanation

A tabletop scenario is an informal, discussion-based session in which a team discusses their roles and responses during an emergency, walking through one or more example scenarios.

A tabletop scenario is the best approach for a company that wants to test a new incident response plan without impacting the environment or using many resources. A tabletop scenario can help the company identify strengths and weaknesses in its plan, clarify roles and responsibilities, and improve communication and coordination among team members.

The other options are more intensive and disruptive exercises that involve simulating a real incident or attack. CompTIA Cybersecurity Analyst (CySA+) Certification Exam Objectives (CS0-002), page 16;

The Chief Information Security Officer wants to find out precisely what happened. Which of the following actions should the analyst take first?

A. Clone the virtual server for forensic analysis

B. Log in to the affected server and begin analysis of the logs

C. Restore from the last-known-good backup to confirm there was no loss of connectivity

D. Shut down the affected server immediately

Correct Answer: A

contamination, or destruction of evidence. Cloning the virtual server can also allow the analyst to safely analyze and
investigate the incident without affecting the original server or its operations.

B. Include references and sources of information on the first page

C. Include a table of contents outlining the entire report

D. Decide on the color scheme that will effectively communicate the metrics
