Digital Forensics and Incident Response

We investigate cybercrime and analyze digital evidence.

The goals of digital forensics investigations are determining the motive for a crime and finding its perpetrator, recovering and analyzing digital devices and digital information to present it as evidence in court, recovering files that have been erased, etc.

Stages of digital forensics

Identification stage

Relevant digital evidence is identified and located. 

Preservation stage

Digital forensics professionals isolate the information or digital device and take steps to secure and preserve the evidence.

Analysis stage

The evidence is examined and reconstructed. Based on this, agents involved in the investigation draw conclusions relevant to the investigation.

Documentation stage

Investigators document the evidence by creating a record of all visible data. This helps visualize the crime scene and makes the review process simpler.

Reporting stage

Investigators create a detailed, easy to comprehend report to summarize and explain the conclusions reached during the investigation.

The field of digital forensics is experiencing a boom in popularity but there are many challenges that make the jobs of digital forensics professionals more difficult. First of all, the increase in the number of devices people use every day and the amount of internet activity most people have daily makes it difficult to conduct investigations. Secondly, hacking tools and tutorials are widely available today, which makes it easier for criminals to conceal their crimes. Another challenge is the sheer amount of digital storage space necessary to conduct such investigations. Finally, since most or even all of the evidence recovered and analyzed by digital forensics experts is non-physical, it makes it more difficult to prosecute the perpetrators and present the evidence in court.

Digital forensics is widely used in fraud and bankruptcy investigations, industrial espionage and intellectual property theft cases, employment disputes, issues with inappropriate internet use by employees, etc.

There are wireless, network, database, disk, email, memory, mobile phone and malware forensics.

Digital forensics can help identify and track down hackers and cybercriminals no matter where in the world they are located, it also allows to obtain, analyze and interpret evidence that can later be used in court. It can also help businesses obtain information relevant to their networks and systems that might have been compromised.

Yes, there are a few disadvantages associated with the digital forensics approach. First of all, prosecutors can face difficulties when admitting digital evidence into court since it is necessary to prove that the data hasn’t been tampered with. Secondly, creating and storing digital evidence is very expensive, plus, if the programs and tools used to deal with the data do not meet strict standards, then the evidence might not be admissible in court. Finally, prosecutors, attorneys and judges in the case need to have sufficient technical knowledge.
