The task we consider is counteraction to the information security incidents. The special feature of the described solution is an integrated application of the methods ensuring implementation of the preventive measures aimed at increasing the complexity of information security threat implementation on a compact device. It provides tasks required for support of wireless communication channels in an environment exposed to an information influence. A prototype of the compact device based on form-factor PC-104+ relevant to the set objectives is offered and tested, its operation principles are described. There is an assessment of response to information attacks, and the states of the devices are modeled in various modes and during introduction of additional protection elements.
