Non-obvious sources include RFID tags, and web pages which must be preserved as they are subject to change.
What is the first rule of digital forensics?
The first rule of digital forensics is to preserve the original evidence. During the analysis phase, the digital forensics analyst or computer hacking forensics investigator (CHFI) recovers evidence material using a variety of different tools and strategies.
Which is the first type of forensics tool?
Identification. It is the first step in the forensic process. The identification process mainly includes things like what evidence is present, where it is stored, and lastly, how it is stored (in which format). Electronic storage media can be personal computers, Mobile phones, PDAs, etc.

Incident response is typically broken down into six phases; preparation, identification, containment, eradication, recovery and lessons learned.
What are the 4 steps of the forensic process?
The first digital forensic process model proposed contains four steps: Acquisition, Identification, Evaluation and Admission. Since then, numerous process models have been proposed to explain the steps of identifying, acquiring, analysing, storage, and reporting on the evidence obtained from various digital devices.
