An actual methodological problem related to increasing the efficiency of training specialists in the field of information and telecommunication technologies is considered. The article substantiates the effectiveness of gamification as a new way of organizing education, which has great pedagogical potential. It is proved that the use of computer games tools in the educational process, firstly, enhances the subject's motivation to pay stronger and better attention to educational activities, secondly, prolongs the commitment to the task and, finally, increases the likelihood of achieving the goal. The features of the application of this approach in the training of specialists in the field of information technology, information security are revealed. Examples of the implementation of a new direction in the form of cyber polygons, virtual computer laboratories are considered. Additional measures have been developed and proposed to complement the methodology of information technological expertise. The final methodology for the investigation of computer crimes has been compiled, taking into account the requirements for the collection, processing and storage of information from an information security specialist. This methodology forms the basis of the computer forensics laboratory. The laboratory is proposed as an additional method of training specialists, implemented in the same concept as cyber polygons, virtual laboratories, etc. The main structure of the laboratory is revealed, the sequence of the applied stages of information technology expertise within the scope of the exploitation of the laboratory of computer forensics is given.
