6 Key skills of a Digital Forensics Investigator

The terms ‘forensics’, ‘digital forensics‘, ‘computer forensics‘, or ‘cyber forensics’ gives the impression of law enforcement. Whereas, in reality, digital forensics plays an important role in cybersecurity. Digital forensic is an independent team of cyber forensic is an expertise similar to other cybersecurity teams.

Proficient standards to be a certified cyber forensic investigator

Owing to a continuous demand for digital forensic training by the companies, appreciable number of certifications are available. Employers preferably look for certified forensic investigators having key-skills on digital forensic. The most common standards that a certified digital forensic investigator should have are as follows:

“Practitioners require technical and professional training in digital forensics principles and processes.” – Jason Jordaan, principal forensic scientist at DFIRLABS, at the ITWeb Security

Defeating anti-forensics techniques

Computer forensic tools allow cyber forensic investigators to retrieve deleted files. On other hand, anti-forensic tools do the reverse. Anti-forensic tools and techniques work against cyber forensic tools. The anti-forensic tools alters, hides, or deletes the information. Anti-forensic tools also implicate users by introducing fake evidences, or by exploiting bugs in the tools, and more. A digital forensic investigator is the one who should have the knowledge and skill to identify and mitigate anti-forensic tools and techniques.

Understanding hard disks and file systems

Hard disk and internal files serve as important sources of information to the forensic investigator. Hence, an investigator should be aware of behavior and structure of hard disk. A cyber forensic investigator should be able to retrieve, protect, and store the information from the hard disk drive. The procedure of file system is also important during investigation as it relates with the hard disk again.

Operating system forensics

Operating system forensic is the process of identifying evidences from the operating system. It involves extracting and analyzing information from the operating systems of any device. The common operating systems like MAX, Windows, and Linux are usually targeted for criminal activities. A cyber forensic investigator should have a complete knowledge of these systems to trace the cyberattacks.

Investigating email crimes

Due to large dependency on the electronic communication channels, email has evolved as a preferred source of communication. The reliable nature of emails has become a powerful tool for criminals. They use emails to perform phishing and other common cyberattacks in large volumes. Regional laws govern email crimes except those that are agreed globally. The trailing emails can be a great source of information to the forensic investigators.

Cloud forensic

Cloud computing is an emerging technology, which many organizations are adopting the trend. On another hand, due to their potential repository of data, attackers perpetrate various attacks. The attackers make their attempts continuously to gain anonymous access over the cloud networks and retrieve the information. A cloud forensic implies the application of forensic investigation in a cloud environment. The cloud network involves both public and private networks. A digital forensic investigator is well-versed with cloud forensic to get through the investigation process.

Dawie Wentzel, Head of Cyber Forensics Investigation at Absa Group has shared immense information on the latest tools and methods to collect cloud-stored data in accordance with evidentiary requirements. During his webinar via Cyber Talks, Dawie talked about the numerous challenges of legally obtaining cloud-stored electronic evidence and possible solutions. Watch the full Cyber Talk here:

Mobile forensics

Mobile device forensics is the process of recovering digital evidence from mobile phones during the investigation process. A certified digital forensic investigator can examine and report possible digital evidence sources from mobile phones. The investigator collects the evidence to present in the court of law. The certified forensic investigators analyze the mobile phones for message history, call history, pictures, or other data on the memory to trace the perpetrators of crimes.

The Computer Forensic Hacking Investigation (C|HFI) is a recognized certification on cyber forensic from EC-Council. The certification validates the candidates’ skills in identifying perpetrators’ footprints and gather the evidence to produce in the court of law. C|HFI is a vendor-neutral certification that fortifies the application knowledge of law enforcement personnel, security officers, military personnel, system administrators and everyone concerned of the integrity of the network infrastructure.
