CompTIA Security+ - Secure System Design Principles Example Questions

Test your knowledge of Secure System Design Principles

Question 1

A cybersecurity team is performing a forensic investigation and suspects that sensitive data was transferred out by hiding it within a video. What method is most likely used?

Correct Answer: Video steganography

Video steganography is the process of hiding information within a video file by altering audio, visual, or data streams. This method is suitable for transferring sensitive data without raising suspicion, unlike the other options provided.

Question 2

An intelligence officer needs to exchange sensitive information with another officer. They decide to hide the message within a seemingly harmless file. Which method would be the most effective?

Correct Answer: Steganography

Steganography is the best method for hiding a message within another file, as it is difficult to detect and can provide plausible deniability. The other options are either not suited for hiding messages or too easily detected.

Question 3

A new security vulnerability has been discovered in an existing application. What phase of the SDLC should the vulnerability be addressed?

Correct Answer: Maintenance phase

The maintenance phase of the SDLC includes addressing security vulnerabilities and implementing patches. This phase occurs after the application has been deployed and is being monitored and maintained.
