METHODOLOGY OF COMPUTER CRIME INVESTIGATION (2024)

FAQs

What is the methodology of computer forensics investigation? ›

CHFI presents a methodological approach to computer forensics, including searching and seizing digital evidence and acquisition, storage, analysis, and reporting of that evidence to serve as a valid piece of information during the investigation.

THE COMPUTER CRIME INVESTIGATIVE METHODS DESCRIBED INVOLVES SEVEN PHASES: INITIAL INVESTIGATION, INVESTIGATION PLANNING, INFORMATION GATHERING AND ANALYSIS, INTERVIEWING AND INTERROGATION, TECHNICAL DATA SYSTEMS REVIEW, FORENSIC INVESTIGATION, AND CASE PRESENTATION IN COURT.

Techniques used in computer forensics

Computer forensic investigations use a combination of techniques and expert knowledge. Some common techniques include the following: Reverse steganography. Steganography is a common tactic used to hide data inside any type of digital file, message or data stream.

In conclusion, the digital forensics investigation process involves several stages, including identification, collection, analysis, reporting, and presentation. By following a structured and methodical approach, cyber forensic companies can gather, analyze, and preserve digital evidence in a legal and ethical manner.

The investigative methodology is a combination of practices, procedures, processes, routines, conventions, and theories and techniques through which police respond to a crime.

Methodology? In cybersecurity, a risk assessment methodology is a process or framework for identifying, evaluating, and remedying potential threats, risks, and vulnerabilities within an organization's technical infrastructure.

Signature-based detection uses known digital indicators of malware to identify suspicious behavior. Lists of indicators of compromise (IOCs), often maintained in a database, can be used to identify a breach. While IOCs can be effective in identifying malicious activity, they are reactive in nature.

In simple terms, it involves the process of: Identifying, analyzing, and tracking digital evidence to uncover the perpetrators and their motives. Learning about the case and assessing the situation. Conducting the initial investigation.

Computer forensic science (computer forensics) investigates computers and digital storage evidence. It involves examining digital data to identify, preserve, recover, analyze and present facts and opinions on inspected information.

What are the 5 rules of digital evidence? ›

However, there are five general rules of evidence that apply to digital forensics and need to be followed in order for evidence to be useful. Ignoring these rules makes evidence inadmissible, and your case could be thrown out. These five rules are—admissible, authentic, complete, reliable, and believable.

Explanation. Acquisition (without altering or damaging), Authentication (that recovered evidence is the exact copy of the original data), and Analysis (without modifying) are the three main steps of computer forensic investigations.

The complete definition of computer forensics is as follows: "The use of scientifically derived and proven methods toward the preservation, collection, validation, identification, analysis, interpretation, documentation and presentation of digital evidence derived from digital sources for the purpose of facilitating or ...

Forensic investigation is defined as the process of reviewing events triggered by security controls to assess the level of risk to an organization and determine if a full investigation is necessary, following established policies and procedures for escalation and governance documentation.

Computer forensics is a field of technology that uses investigative techniques to identify and store evidence from a computer device. Often, computer forensics is used to uncover evidence that could be used in a court of law. Computer forensics also encompasses areas outside of investigations.

Traditional forensic analysis methods include the following: Chromatography, spectroscopy, hair and fiber analysis, and serology (such as DNA examination) Pathology, anthropology, odontology, toxicology, structural engineering, and examination of questionable documents.

Computer forensics investigators employ various methodologies such as reverse steganography, data carving, live analysis, keyword searches, and cross-drive analysis to retrieve and scrutinize relevant data for evidence of misconduct.

Network forensics investigates network traffic patterns and data acquired while in transit in a networked environment. It involves examining traffic data, logs, and other data that can be used to investigate cybercrime, network security incidents, and data breaches.

Forensic Audit Methodology

Forensic audit involves efforts to resolve allegations or signs of fraud when the full facts are unknown or unclear; therefore, it seek to obtain facts and evidence to help establish what happened, identify the responsible party, and provide recommendations where applicable.
