It requires the encryption of all personal data

It governs the legal requirements for search and seizure of digital evidence

It mandates the use of forensic software tools during investigations

It establishes the admissibility of digital signatures in court

Question 35: What does the term "file slack" describe in digital forensics?

The space used by temporary files

The unused space between the logical end of a file and the end of the storage block
