Essential Objectives of Digital Forensics
Digital forensics involves recovering, analyzing, and preserving electronic materials (such as computers, hard drives, and mobile devices) in a way that ensures their admissibility as evidence in a court of law.
2. Postulate the crime motive and the main culprit identity
One of the main objectives of this process is to help investigators determine the motive behind the crime and identify the person or persons responsible for it.
3. Design procedures to avoid digital evidence corruption
With procedures designed at a suspected crime scene, you can avoid the corruption of the digital evidence obtained. This way, it can be successfully used in court.
4. Recover deleted files and partitions
Digital forensics specialists are trained to get back lost files and partitions from any digital device and verify their authenticity.
5. Identify the evidence and estimate the potential impact on the victim
It is great for finding the evidence fast and assessing how much damage the bad actors caused to the target.
6. Produce a comprehensive computer forensic report
A digital forensic report offers a complete report on the investigation process, from the initial discovery of evidence to the forensic analysis of data.
7. Preserve the evidence by following the chain of custody
To ensure that evidence is admissible in court, it must be meticulously documented and preserved. That’s why the chain of custody procedures are important
Digital Forensics: Example Uses
In recent times, commercial organizations have been using digital forensics in a variety of cases. Here are some example uses of digital forensics:
1. Intellectual Property Theft
A digital forensic investigation can help identify who accessed proprietary information, when it was accessed, and how it was procured. Such investigations can assist in building a case for legal action against perpetrators of IP theft.
2. Industrial Espionage
Thanks to digital forensics techniques, you can identify whether competitors or employees accessed, modified, or deleted any confidential files or trade secrets. In such cases, victims can seek legal remedies for the theft of trade secrets.
3. Employment Disputes
Employers can resort to digital forensics to investigate whether employees breached workplace policies or engaged in misconduct. For instance, this can help you examine claims of discrimination, bullying, or mistreatment.
4. Fraud Investigations
Digital forensics experts can help uncover evidence of fraudulent activities such as financial manipulations, embezzlement, or fraudulent claims. This can serve as evidence to prosecute the perpetrators.
5. Forgeries
Digital forensics is great for examining documents, signatures, and stamps for forgeries or alterations. This helps with disputes or investigations of legal documents such as contracts or wills.
6. Bankruptcy Investigations
The process can help investigate financial records to determine whether assets have been hidden or transferred to other parties to avoid creditors. This way ensures a fair distribution of assets in bankruptcy proceedings.
7. Inappropriate Use of the Internet and Email in the Workplace
You can use digital forensics to investigate misuse of company property, such as inappropriate use of the Internet or email in the workplace. This should help to identify and deter such behavior.
8. Regulatory Compliance
With digital forensics, organizations work to verify compliance with regulatory requirements. This can help you demonstrate compliance or identify areas of non-compliance that need to be addressed.
Advantages of Digital Forensics
- Ensures the integrity of computer systems: Digital forensics helps to secure the integrity of computer systems and networks. It identifies the source of the cyber attack and helps in tracing the attack to the source.
- Produces evidence in court: In a court of law, digital forensics is significant evidence. It collects digital data and evidence from various devices that can be used to convict cybercriminals.
- Captures important information: It helps organizations capture important information should their computer systems or networks be compromised. This way, companies can protect their clients, employees, and their assets.
- Efficiently tracks down cybercriminals: Cybercriminals can act from anywhere in the world. Digital forensics helps track them down efficiently and quickly, irrespective of where they are operating from.
- Protects organizations’ resources: Digital forensics helps to protect an organization’s money, data, and valuable time. It can quickly identify the source of a cyber attack and prevent further damage.
- Extracts, processes, and interprets factual evidence: This process provides factual evidence that can be presented in court. It can extract, process, and interpret this evidence in a way that is meaningful and understandable.
Its Disadvantages
- Evidence subjected to tampering: Digital evidence can be tampered with. In a court of law, it must be proven that there is no tampering with the evidence presented.
- Extremely costly: Producing electronic records and storing them is a costly affair. It requires significant investment and resources.
- Requires extensive computer knowledge: Legal practitioners must have extensive knowledge of computers to use digital forensics effectively.
- Requires authentic and convincing evidence: In a court of law, the evidence must be authentic and convincing. This can be challenging, primarily if the offender is tech-savvy.
- Evidence disapproved by justice: If the tool used for digital forensics is not according to specified standards, then the evidence can be disapproved by justice in the court of law.
- Lack of technical knowledge: Investigating officers who lack technical knowledge might not offer the desired result when using digital forensics.
Major Challenges Faced by Digital Forensics Experts
Where it is a crucial aspect of investigating cybercrime, digital forensics faces challenges that make the process of uncovering evidence and prosecuting criminals difficult.
- Increase in the use of computers and access to the Internet: As technology advances and computing devices become more ubiquitous in our everyday lives, the volume of digital data being produced also grows significantly. With so much electronic evidence being generated, it can be a challenge for investigators to successfully extract and analyze relevant data from a sea of information.
- Easy availability of hacking tools: Hacking tools are readily available on the internet and this means that even amateur hackers can carry out cyber attacks. Using these tools, hackers can easily cover their tracks. This makes it harder for digital forensics experts to trace the source of the attack and recover any relevant evidence.
- Lack of physical evidence: Unlike traditional crime scenes, hacking incidents rarely leave any physical evidence behind. This makes it more difficult for forensic experts to gather evidence, which is mostly digital. Without compelling evidence, prosecutors may not have enough basis to charge suspects and secure a conviction.
- Large amounts of data: With storage space now measured in terabytes, digital forensic investigators need to sift through vast amounts of data. In other words, they need advanced techniques and technologies to process and analyze the data.
- Rapid technological changes: Tech evolves at a rapid pace, and digital forensics experts need to be able to keep up with new developments. This requires them to continuously upgrade their skills and tools to stay ahead of cyber criminals who are always finding new ways to evade detection.Takeaway: Digital forensics is a highly effective tool in today’s digital age. While it presents several advantages, it also has certain drawbacks. By taking the downsides and challenges into consideration and using digital forensics correctly, investigators and legal practitioners can better protect their organizations from cyber threats and ensure justice is served in a court of law.
