Question 980
A security engineer suspects steganography in images uploaded to an external content site. Which conclusion or control should be prioritized in the test plan?
Explanation
Correct Answer
Treat steganography as a hypothesis and assess with safe forensic analysis. This answer directly addresses the described constraint. Hidden payloads may exist within apparently benign media files. Successful validation requires: A synthetic embedded marker is detected in an approved sample image.
Incorrect Answers
That approach concerns a different situation: a project storage account is shared with an unrelated external cloud account. Cloud-native access may enable transfer without conventional internet downloads. The required result is that a synthetic embedded marker is detected in an approved sample image. The appropriate action is: Treat steganography as a hypothesis and assess with safe forensic analysis.
That relates to a different issue: An attacker stages files in a hidden alternate data stream on an NTFS test volume. Alternate streams can hide data outside ordinary visible file content. That is not a direct remedy for the requested outcome: A synthetic embedded marker is detected in an approved sample image. The appropriate action is: Treat steganography as a hypothesis and assess with safe forensic analysis.
This action applies to a different case: A test team wants to assess whether confidential files could be moved to personal web text storage. Public paste sites may provide an outbound data path not intended for business use. It does not establish the present requirement, where a synthetic embedded marker is detected in an approved sample image. The appropriate action is: Treat steganography as a hypothesis and assess with safe forensic analysis.
