Study Notes
Computer Forensics
- Digital forensics is a relatively new science that includes the forensics of all digital technology.
- Computer forensics is a field of technology that uses investigative techniques to identify and extract evidence from a computer device.
- It is used to uncover evidence that could be used in a court of law.
- Computer forensics follows a similar process to other forensic disciplines and faces similar issues.
Forensic Process
- Inputs: Target Person / Digital Device
- Processes: Collect, Analyze, Report
- Output: Answer to Question, well-grounded answers
Example Case
- Phone tracing was used to determine the suspect's location at the time of the murder.
- The IMEI number was used to track the phone.
Digital Evidence Integrity
- Evidential integrity requires that any digital evidence being examined not be changed in any way by the digital forensic examiner.
- Evidence integrity needs to be protected in order to make it admissible in the court of law.
Chain of Custody
- Chain of Custody refers to the logical sequence that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence in legal cases.
- Each step in the chain is essential as if broken, the evidence may be rendered inadmissible.
- Preserving the chain of custody is about following the correct and consistent procedure and hence ensuring the quality of evidence.
- The chain of custody ensures that evidence is protected, data integrity is preserved, proof is undeniable, and the case is closed.
Computer Hardware and Software
- Topics to be covered include secondary storage media, file systems, file structure, data representation, Windows registry, encryption, hashing, and salting, memory and paging, and other notable artifacts.
Secondary Storage Media
- Refers to media where data is stored for long-term preservation.
- Examples include hard drive types (HDD, SSD) and their characteristics.
- SSD drives have improvements of reliability and transfer speed, but are not as cost-effective as HDD.
