Making yourself aware of digital forensics

In a world driven by technology, the importance of digital security has grown exponentially, especially in Singapore. Digital forensic tools help detect and investigate data stored on digital devices to combat increasing computer crime. Digital forensics is an exciting field of forensic study encompassing the investigation and recovery of digital information found in electronic devices, most frequently concerning online computer crime. Electronic data can be stored in many different formats, including email, digital media such as files, emails, compact disks, digital photographs, digital audio recordings, and video. It is necessary to apply a range of digital forensics techniques to reconstruct the digital data from any of these sources.

Digital forensics is an exciting field of forensic study encompassing the investigation and recovery of digital information found in electronic devices, most frequently in relation to online computer crime. Electronic data can be stored in many different formats including email, digital media such as files, emails and compact disks, digital photographs, digital audio recordings and video. In order to reconstruct the digital data from any of these sources, it is necessary to apply a range of digital forensics techniques. This paper will provide an introduction to digital forensics and introduce some of the common techniques used.

Digital forensics cannot be regarded purely as an investigation technique. It also involves the documentation and the quality control of evidence. In the process of digital forensics it is necessary to adhere to strict preservation procedures such as keeping track of preservation methods, software integrity, encryption and anonymity. A key feature of digital forensics is the use of controlled data exfoliation in order to recover deleted data and to reveal embedded keys and passwords. Another feature of digital forensics is the use of digital signatures, which are used as fingerprints of documents in order to determine their authenticity.

Once all the digital forensics tools have been assembled, the investigator needs to think carefully about how to analyse the evidence collected and how to reconstruct the digital data. There is a range of software tools which can be used for digital forensics analysis. With the growing complexity of organizations, including cybercrime, law enforcement agencies and independent investigators need more access to a wide range of products and digital forensic tools, including protecting, investigating, and e-discovery of sensitive data. We provide an integrated platform for accessing these various tools, thereby ensuring complete security for our customers in today’s digital world.
