Study Notes

Roles and Objectives in Digital Forensics

Digital forensic examiners serve as critical investigators in cyber crime cases, analyzing evidence effectively and ensuring its integrity.
Maintaining chain of custody is crucial during investigations to guarantee that evidence is preserved and remains admissible in court.
After evidence collection, investigators perform analysis, aiming to reconstruct events or identify perpetrators.
The main objective of digital forensic investigations is to uncover and present factual evidence related to cyber incidents.

Computer Forensics Fundamentals

Computer forensics is defined as the process of collecting, analyzing, and preserving data from digital devices to aid legal investigations.
A significant milestone in computer forensics occurred in 2000 when the FBI established the Computer Analysis and Response Team (CART).
The primary goal of computer forensics is to recover, analyze, and preserve digital evidence to support legal proceedings.

Objectives and Functionality

Computer forensics ensures the integrity and admissibility of digital evidence during investigations.
Key objectives of computer forensics include identifying, preserving, and analyzing electronic data.
Understanding regional laws is essential for forensic investigators to comply with legal requirements during evidence collection.

Phases and Methodologies

The preservation phase in computer forensics involves securing digital evidence to prevent alteration or loss.
Activities unrelated to computer forensic methodologies may include unauthorized access or tampering with evidence.
Major disruptions to businesses are often caused by security incidents like data breaches and ransomware attacks.

Financial and Security Considerations

Financial implications of responding to security incidents can be substantial, potentially leading to significant losses.
The key goal of forensic readiness is to prepare organizations for efficient and effective responses to potential incidents.
Effective security measures encompass information, network, and physical security to protect organizational assets.

Security Domains

Information security ensures confidentiality, integrity, and availability of data.
Network security aims to protect data integrity and accessibility across networks.
