CompTIA CASP+ (CAS-004) — Question 116

Which of the following is a benefit of using steganalysis techniques in forensic response?

Answer options

• A. Breaking a symmetric cipher used in secure voice communications
• B. Determining the frequency of unique attacks against DRM-protected media
• C. Maintaining chain of custody for acquired evidence
• D. Identifying least significant bit encoding of data in a .wav file

Correct answer: D

Explanation

The correct answer, D, is right because steganalysis specifically aims to uncover hidden information in files, such as identifying least significant bit encoding in .wav files. The other options do not relate to the core function of steganalysis; A pertains to cryptography, B relates to attack frequency analysis, and C addresses evidence handling, which are outside the scope of steganalysis.
