The need to develop existing approaches and scientific and technical solutions in the field of information security is caused by the rapid development of cyber-physical systems that require adaptation of protection mechanisms to new architectures, technical limitations and features of operation. One of the important, but poorly considered in the world literature areas of protection of cyber-physical systems, are the issues of building effective protectors that mitigate threats to the accessibility of interfaces at the application level. Disruption of the availability of control subsystems for the objects in question can lead to tragic consequences, so a comprehensive analysis and modernization of approaches to protect them from DDoS attacks is already required. This study proposes an approach to protecting cyber-physical system control interfaces from external influences aimed at disrupting accessibility due to the lack of technical capability to echelle the protection of application software. As the object of the cyber-physical system, a virtual polygon of unmanned vehicles was used. An analysis of applicability of existing approaches to protection against application layer attacks for the selected class of objects is given, an adapted approach to object protection is proposed and its effectiveness is investigated.
