Personal computers, laptops and personal smart devices have had a steady increase in storage and computational capacity capabilities over the years, where it has become common with terabytes in storage space. Moreover, the emergence of the Internet of Things and Smart Applications bringing a new horizon into how the data affects our life and the world around us. Despite the role of modern technologies in improved quality of life and making the world better place, the surface of cyber threats and anticipated cyber-attacks has been brought to a new level, as it is seen by ransomware and Mirai IoT botnets. Conventional Computer Forensics is no longer efficient because the term Computer has acquired much broader meaning over the last decades. Multiple aforementioned disruptive technologies result in the agile ICT environment, which constantly changes its state as a response to external influence.
Moreover, previously unseen things like IoT orphan devices become a standard practice due to the relative inexpensiveness of the technologies, connectivity and power supply. We are surrounded by interconnected components, which we might not know about, and those collect personal data, sensitive information and, often, has multiple security vulnerabilities. Big data paradigm is undeniable in every aspect of cybercrime investigations. As a result, there is a strong need for novel methods in future to aid cybercrime investigations and police on large-scale data. Therefore, it is essential to look for an advanced Artificial Intelligence method capable of handling such challenges and bringing down the amount of manual labour required by police officers. Finally, providing more efficient data handling and digital evidence discovery will build a strong foundation for intelligent decision support in future smart cities across the globe.
