As mentioned in your textbook, steganography is the art and science of writing hidden messages. The goal is to hide information so that even if it is intercepted, it is not clear that information is hidden there. The most common method today is to hide messages in pictures.
Technically speaking, cryptography is the study of encryption and decryption methods. Cryptography is not so much about hiding a message, as with steganography, but rather about obfuscating the message so that it cannot be read.
Answer the following question(s):
- Do you believe steganography complicates forensic investigations? Why or why not?
- Discuss the impact on forensics of inventing one’s own cryptographic methods.
Two common techniques for recovering data after logical damage to a file system are consistency checking and zero-knowledge analysis. Another technique for data recovery is file carving, which extracts data from a single file from a larger set of data, such as an entire disk or partition.
Answer the following question(s):
- Assume your solid-state disk (SSD) was accidentally reformatted and your data was not backed up. Which technique would you try first and why?
- Which technique do you consider to be a last resort? Why?
