Digital Forensics
Digital forensics is the process of identifying, preserving, analyzing, and presenting digital evidence in a way that is legally admissible. It is a critical discipline within cybersecurity, used to investigate and respond to cybercrimes, security breaches, and other incidents involving digital devices or data.
Compupter & Mobile Device Forensics:
This branch focuses on investigating data stored on computers, mobile devices, such as smartphones and tablets, and other digital storage devices, such as hard drives, SSDs, and USB drives. The goal is to recover, analyze, and interpret files, data, text messages, call logs, emails, photos, and GPS locations, that may be relevant to an investigation, even if these items were deleted.
Network Forensics:
Network forensics deals with monitoring and analyzing network traffic to detect and investigate cyber incidents. It involves capturing and analyzing packets of data as they travel across the network to identify malicious activities, such as data exfiltration, unauthorized access, or denial-of-service attacks. Network forensics is crucial in tracing the source of an attack and understanding the extent of a breach.
Malware Forensics:
Malware forensics involves analyzing malicious software to understand its behavior, functionality, and origin. This can include reverse engineering the malware code, identifying its payload, and determining how it infected the system. This type of analysis helps in understanding the attack vector and mitigating future threats.
Forensic Data Analysis:
Examining large sets of data to identify patterns, correlations, or anomalies that may indicate fraudulent activities, insider threats, or other malicious behavior. This type of analysis often involves advanced tools and techniques to sift through vast amounts of data, such as logs from financial transactions or communication records.
