An organization's information security manager is performing a post-incident review of a security incident in which the following events occurred:

* A bad actor broke into a business-critical FTP server by brute forcing an administrative password

* The third-party service provider hosting the server sent an automated alert message to the help desk, but was ignored

* The bad actor could not access the administrator console, but was exposed to encrypted data transferred to the server

* After three hours, the bad actor deleted the FTP directory, causing incoming FTP attempts by legitimate customers to fail

Which of the following could have been prevented by conducting regular incident response testing?

Answers

The brute force attack
D.
Stolen data
Answers
D.
Stolen data
Suggested answer: A

Explanation:

Ignored alert messages could have been prevented by conducting regular incident response testing because it would have ensured that the help desk staff are familiar with and trained on how to handle different types of alert messages from different sources, and how to escalate them appropriately. The server being compromised could not have been prevented by conducting regular incident response testing because it is related to security vulnerabilities or weaknesses in the server configuration or authentication mechanisms. The brute force attack could not have been prevented by conducting regular incident response testing because it is related to security threats or attacks from external sources. Stolen data could not have been prevented by conducting regular incident response testing because it is related to security breaches or incidents that may occur despite the incident response plan or process.
