We propose a resource-oriented architecture of a rational agent for a network intrusion detection system. This architecture describes the behavior of a rational agent after detection of unwanted network activities. We describe the creation of countermeasures to ward off detected threats. Examples are created based on the proposed architecture, describing the process during a rational agent detection. We have described these examples by linear BDI logic behavioral formulæ, that have been proven by Gentzen sequent calculus.

We teach the subject of the semantics of programming languages at the graduate level, where we present different approaches to the definition of formal semantics for imperative languages. In this paper, we present a new teaching tool for visualization of semantics computation of a toy imperative language by the small-step semantic method. We have developed a responsive web application that simulates a computation of a program’s semantics as is done by hand on a blackboard.
