A digital forensics professional must know basic IT skills, understand computer architecture and networking, and have analytical and investigative skills, as well as strong attention to detail. Why do think all of these skills are necessary? Please explain.

Digital forensics is the act of preserving, identifying, extracting, and documenting evidence from computers to be used in a court of law later. It involves retrieving evidence from digital media like computers, phones, or networks. Digital forensics exists due to failed cyber security tactics. Digital forensics helps track hackers, retrieve stolen data, incident investigation processes, and provide the digital evidence retrieved (Le-Khac, 2019).

A digital forensics professional must possess some necessary skills to retrieve this computer evidence required. He/she must possess suitable digital devices and technical concepts understanding and also have computer systems experience. One has to possess the efficient technical knowledge to determine and respond to security breaches and network hacks. Computer networking knowledge is vital for a forensics investigator. The forensic expert’s connectivity knowledge and networking concepts should be top-notch since the investigation will be widespread to every LAN system connected (Garrison, 2010).

A digital forensics specialist should possess adequate operating system knowledge. In an instance of a cybercrime investigation, one should access the operating systems and all other endpoint devices to conduct a successful investigation. This process of analyzing evidence and interpreting cyber data during cyber-attacks needs often requires advanced analytical skills. A high level of analytical thinking with precise observance is required to uncover through the acquired evidence. Investigative skills are an added advantage since digital forensics deals with cybercrimes and criminal law knowledge. A digital forensics analyst needs to have extreme attention to detail when dealing with digital evidence from cyber-attacks. It’s imperative to pay attention to any detail to ensure one does not miss anything (Gogolin, 2012).

Methods of Digital Forensics used to Solve Crimes

Digital forensics is the process of investigating by accumulating evidence from digital equipment like computers, networks, cloud, hard drive, and any endpoint system connected to the technological infrastructure. Digital forensics involves retrieving evidence by preserving or recording the digital devices’ state, analyzing them, and reporting the information recovered. In instances of cyber-attack crimes, a digital forensics examiner analyzes the digital attack to retrieve evidence to help track the attackers. In today’s world, with more than 95% of people having cellphones, the data existence is staggering. The mobile phones involved in the investigation and devices like laptops, desktops, smart watches, and all other devices that fall under the internet are capable of data exchange. Data forensics has been particularly stressed by the emergence of higher sophisticated devices (Kävrestad, 2018).

Digital forensic methods are used to solve the crime by law enforcers and investigators every day. For example, there was this case in the United Kingdom back in 2009 of a particular guy, Krenar Lusha, who was an illegal immigrant to the UK. He was arrested based on his internet search engine pattern. He was found guilty due to the help of digital forensics. Once the computer forensics experts investigated his laptop, they discovered that he had downloaded a manual of 4300GM that contained information to make search belts and explosives. This opened up the case, giving them the warrant for further investigation to search his house, where they found 71.8liters of petrol, potassium nitrate, and a live shotgun cartridge. Digital forensics also showed other evidence that he had used his laptop to message people via MSN, where he described himself as a terrorist and a sniper. In the messages, he portrayed himself as someone who hated Jewish and American people and wanted to see them dead. All this information was retrieved from his laptop using digital forensics and used as digital evidence in court (Roussev, 2016).

Several criminal cases have used digital evidence to uncover hidden scams. In most criminal cases, whenever there is not enough evidence gathered from all the sources acquired, digital forensics will often provide adequate evidence to convict the person. Most of these digital devices that we use can store 99%of the information that we feed them, and in case of a criminal investigation, they come in handy. Digital forensics is an effective method to solve crimes commonly used today by investigators (Husain & Khan, 2019).
