A security team is designing a steganography detection system for a high-security environment. The team must detect hidden data in images, audio, and video files. The team has limited computational resources and needs to prioritize detection methods. Which approach should the team take to balance detection accuracy and resource usage?

Use only visual inspection by human analysts to avoid computational costs

Use a triage approach that starts with fast statistical analysis and only runs deeper analysis on files that show anomalies

Use a single steganalysis tool that is known to detect the most common techniques

Run all available steganalysis tools on every file to maximize detection

What is the primary purpose of steganography?

To authenticate the sender of a message using digital signatures

To hide the very existence of a message within a cover medium

To encrypt a message so that it cannot be read without a key

To compress data so that it occupies less storage space

A company's security team is evaluating steganography tools for a legitimate internal project that requires hiding confidential data in images. The team must choose a tool that minimizes the risk of detection by statistical steganalysis. The images will be shared externally, so the embedding must not degrade image quality noticeably. Which tool feature should the team prioritize?

Support for encrypting the hidden message before embedding

Support for LSB insertion with a fixed number of bits per pixel

Support for adaptive steganography that adjusts embedding strength based on image content

Support for embedding in the image's metadata

A security consultant is evaluating steganography tools for a client who needs to hide data in audio files for a legal compliance project. The client requires that the hidden data be recoverable even if the audio file is compressed to MP3 format. Which tool feature should the consultant prioritize?

Support for spread-spectrum embedding that is robust to lossy compression

Support for LSB insertion in WAV files

Support for phase coding that embeds data in the phase of the audio signal

Support for echo hiding that embeds data in the echo of the audio signal

What does a visual attack in steganalysis involve?

Using statistical tests to detect anomalies

Looking at the image or audio waveform for visible or audible anomalies

Comparing the file to known steganography tool signatures

Examining the file's metadata for hidden messages

Steganography and Steganalysis ECES Practice Questions (Page 5)

Part of the Applications of Cryptography domain, which makes up ~25% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~13–20 in this domain), expect 3–5 from this objective — we provide 42 practice questions to prepare you well beyond it.
