Digital forensics investigation is not restricted to retrieving data from the computer, as criminals breach laws and small digital devices are now extensively used.
Digital forensic analysis and investigation is applied to various digital devices. They are as 1. Computer forensics, 2. Mobile device forensics, 3. Network forensics, 4. Forensic data analysis, 5. Database forensics, and 6. IoT Forensics. Digital forensics is commonly used for criminal law and private investigation. One major limitation of a forensic investigation is encryption, which e disrupts the initial examination where pertinent evidence might be located using keywords.
