As part of the investigation, digital forensics encompasses the identification, gathering, analysis, and reporting of any important digital material found on digital devices connected to computer crimes. Digital forensics can be defined as the process of locating, safeguarding, examining, and presenting digital evidence. The Florida Computer Act of 1978 acknowledged the first computer crimes, and in the years that followed, in the late 1980s and early 1990s, the area of digital forensics experienced rapid growth.
Analysis areas such as storage media, hardware, operating systems, networks, and applications are included. It consists of five high-level steps:
- Identification of evidence: This entails finding evidence of a digital crime in hardware, operating systems, networks, storage media, and/or apps. It is the most crucial and fundamental stage.
- Collection: This stage involves keeping the digital proofs found in the first phase from deteriorating and disappearing over time. The preservation of digital evidence is critical and extremely important.
- Analysis: It entails examining the digital evidence of computer crimes that have been performed in order to identify the perpetrator and identify potential entry points into the system.
- Documenting: This entails thorough documenting of the entire digital inquiry, as well as digital proofs and the vulnerabilities of the attacked system, among other things, to enable future study and analysis of the case and correct presentation in court.
- Presentation: To demonstrate the digital crime committed and identify the offender, all digital evidence and paperwork must be presented in court.
In the context of legal and investigative procedures, digital evidence must be gathered, preserved, analyzed, and presented. This specialized field is known as “digital forensics.” Here is a path to get started if you’re interested in a career in digital forensics:
A)- Foundation for Education:
- A bachelor’s degree in a related discipline, such as computer science, cybersecurity, information technology, or criminal justice, is a good place to start. This serves as the knowledge’s foundation.
B)- Strengthen Technical Skills:
- learn about software and hardware for computers.
- Develop strong knowledge of networks, file systems, and operating systems.
- Recognize programming languages used in digital forensics, such as Python.
C)- Enroll in classes or certification programs in cybersecurity
- As CompTIA Security+, CISSP (Certified Information Systems Security Professional), or CISM (Certified Information Security Manager). These certifications will give you a firm grasp of security concepts.
D)- Courses in digital forensics
- Take classes in digital forensics especially. For example, look for the Certified Digital Forensics Examiner (CDFE) or the Certified Forensic Computer Examiner (CFCE) programs or certificates.
E)- Practical Experience
- Participate in internship programs or do independent digital forensics projects to gain real experience.
- To gain exposure to real situations, think about volunteering for law enforcement organizations or digital forensics labs.
Advantages
- More effective than using memory:
It is usually preferable to have the precise file on hand rather than relying on memory. - As opposed to just relying on memory, using digital forensics techniques to recover files is almost always the superior option.
- Data Preservation: A forensic image is obtained from a physical device (such as a phone, laptop, etc.) while utilizing digital forensics.
- Admissibility in Court Forensic photographs are admissible as digital evidence in a court of law because they preserve the data, ensure that no files may be changed, and replicate the data from the physical device bit by bit.
Disadvantages
- Overly Specific:
This topic of study can be overly specific and narrow when it comes to training in and studying it. - Expensive Equipment:
Due to their high level of specialization and extensive research and development, commercial forensic software and hardware products are typically pricy in terms of cost. - Extended Processing Period:
Data on desktops and mobile devices is constantly growing. Our devices now frequently have 1 TB of data capacity. - It will take more time because digital forensics entails looking at data.
Conclusion
Digital forensics involves the process of identifying, collecting, acquiring, preserving, analyzing, and presenting digital evidence. Digital evidence must be authenticated to ensure its admissibility in a court of law.
The identification of cyber and computer-assisted crime has surely been greatly aided by the forensic investigation of electronic systems. Organizations are emphasizing more and more how crucial it is to have the necessary incident management tools to deal with system abuse. In this procedure, computer forensics is a crucial tool.
In the past ten years, the field of computer forensics has expanded significantly. Industry-driven efforts first concentrated on creating methods and tools to aid in the practical implementation of the technology. A growing amount of academic research has been published in recent years that examines numerous innovative methods for gathering forensic evidence. These new ones appear each year.
