Cybercrime investigation and digital forensics face several challenges, including: This section focuses on the "first responder" role,
: The first rule of digital forensics is to do no harm to the original evidence. This section focuses on the "first responder" role, detailing procedures for identifying, collecting, and preserving digital media at a crime scene. A significant portion is dedicated to creating forensic images (bit-for-bit copies) of storage devices. The manual explains the use of hardware and software write-blockers to prevent data alteration, and the creation of cryptographic hash values (e.g., MD5, SHA-1) to verify the integrity of acquired data throughout the investigation.
A lab manual also addresses the operational aspects of a digital forensic laboratory. This includes guidelines on:
