static verification and software testing are not able to verify software single-handedly. therefore, another approach called run-time verification dealing with verifying software behavior against constraints at run-time received attention. however, the run-time verification faces the problem of verification of run-time activities against the constraints are specified in high-level and abstractl...

Most applications that are in use today inter-operate with other applications, so-called peers, over a network. The analysis of such distributed applications requires that the effect of the communication with peers is included. This can be achieved by writing or generating stubs of peers, or by including all processes in the execution environment. The latter approach also requires special treat...

Today, business continuity depends significantly on the continuous availability of information systems. It is well-known that such systems must be protected against intrusion and denial of service attacks. Historically, many of such attacks used illformed data-packets and/or protocol runs, which did not conform to the protocols’ standards. Attackers exploited vulnerabilities of the protocols’ i...

For software systems that need to adapt to their environment at run-time, run-time verification is useful to guarantee the correctness of their behaviors. Probabilistic model checking using discrete time Markov chain (DTMC) model has been applied to implement run-time verification. A current existing approach provides an efficient run-time verification mechanism by pre-generating expressions fo...

Validation and Verification (V&V) of autonomous robotic system software is becoming a critical issue. Among the V&V techniques at our disposal, formal approaches are among most rigorous trustworthy ones. Yet, level skills knowledge required to use deploy methods usually quite high rare. In this paper, we describe an approach that starts from regular, but rigorous, framework specify components, ...

Run-time monitoring is a lightweight verification method whereby the correctness of a programs’ execution is verified at run-time using executable specifications. This paper describes the verification of the fault protection engine of the Deep-Impact spacecraft flight software using a temporal logic based run-time monitoring tool.

Adaptive systems are able to modify their behaviors to respond to significant changes at run time such as component failures. In many cases, run-time adaptation is simply replacing a piece of system with a new one without interrupting the system operation. In terms of component-based systems, an adaptation may be defined as replacing a system component with a new version at run time. However, u...
