Digital Forensics MCQs Quiz With Answers

The statement is true because a forensic database is an essential component of a digital forensic application. This database stores and manages all the digital evidence collected during investigations, such as images, videos, documents, and metadata. It allows forensic analysts to organize, search, and analyze the evidence efficiently, aiding in the investigation process. Additionally, the database ensures the integrity and security of the evidence, as it can track any changes made to the data and provide a reliable chain of custody.

Digital Forensic is the application of computer science and investigative procedures for a legal purpose involving the analysis of digital evidence. This process includes obtaining proper search authority, maintaining a chain of custody, validating evidence using mathematics, utilizing validated tools, ensuring repeatability of results, preparing reports, and potentially presenting findings by an expert in court.

Digital evidence poses difficulties in handling due to two main reasons: it is easy to destroy and hard to obtain. Firstly, digital evidence can be easily manipulated or deleted, making it crucial to handle it carefully to preserve its integrity. Secondly, obtaining digital evidence can be challenging as it requires specialized tools and expertise to collect and analyze data from various sources. Therefore, the correct answer is "Both A and C" because both the ease of destruction and the difficulty in obtaining digital evidence contribute to the challenges faced in handling it.

The statement "It is the investigator’s job to determine someone’s guilt or innocence" is false. A digital forensic investigator's role is to collect, analyze, and present digital evidence related to a case. They do not have the authority or responsibility to determine guilt or innocence. That is the job of the legal system, such as judges and juries, based on the evidence presented by the investigator.

Real evidence holds the highest value in court. Real evidence refers to physical objects or tangible items that are presented in court to support a claim or provide proof of a fact. This can include weapons, drugs, fingerprints, DNA samples, or any other physical evidence that can be examined and analyzed by experts. Real evidence is considered highly reliable as it is concrete and can be directly observed and evaluated by the judge and jury. It carries more weight than other types of evidence such as documentary evidence, which includes written or recorded materials, testimonial evidence, which is based on witness statements, or demonstrative evidence, which includes visual aids or models used to illustrate a point.

ACSLD stands for the American Society of Crime Laboratory Directors. It is an organization that accredits labs in the field of forensics. Therefore, the correct answer is ACSLD.

Digital forensic analysis focuses on the examination and analysis of digital evidence to uncover and prove facts related to a crime or incident. It involves processes such as data recovery, preservation, analysis, and presentation of evidence. The other options mentioned - authenticity, comparison, and enhancement - are all important aspects of digital forensic analysis. However, proving is not the focus of digital forensic analysis as it is the role of the legal system to determine guilt or innocence based on the evidence provided by the analysis.

The correct answer is I and III. This is because developing a hypothesis based on evidence and testing the hypothesis to look for additional evidence are both steps in the scientific method. Calculating the hash value of the evidence and making imaging of the original evidence are not specific steps in the scientific method, so they are not included in the correct answer.

The primary objective of digital forensic for business and industry is to ensure the availability of service. This means that the focus is on investigating and analyzing digital evidence to identify any potential threats or incidents that may impact the availability of the organization's services or systems. By conducting digital forensic investigations, businesses can proactively detect and mitigate any disruptions or attacks, ensuring the smooth functioning and uninterrupted availability of their services to customers.
