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.
