In this article, the topic of continuous monitoring of the intensity of electromagnetic radiation simultaneously with the development of radio communication infrastructures in the national information network is investigated. Among the most important components of the National Information Network are the access and radio transmission sections. Achieving the requirements that are mentioned as quantitative goals in the documents of the National Information Network is inevitable to use the new cellular communication network such as the fifth generation of communication networks.  New networks will actually increase the intensity of radio radiation due to the denser number of stations. On the other hand, according to the cycle of non-biological defense, the first link of non-biological defense is the constant monitoring of risks and threats. In the direction of Hayman, an electric meter was designed, simulated and built to measure the intensity of electromagnetic radiation and compare it with the permitted levels based on international and national standards.  Simultaneously with the development plans of the national information network and taking into account the charter of citizens' rights in the benefit of citizens from radiation health, the creation of a nationwide integrated network of electric meters for the continuous monitoring of radiation intensity in the country was considered as a need.  The correct location and arrangement of the place of installation of electric meters requires the determination of effective indicators and criteria.  At the end of the article, three categories of indicators from the technical, environmental and social point of view have been identified and suggested for choosing the place of installation of gauges

Cyber-physical systems are a combination of cyberspace and physical processes in which physical systems and processes are monitored and managed by the cyber layer. The purpose of entering the physical world is to increase the flexibility and efficiency of systems. Today, these systems play a key role in critical infrastructure. This development, on the other hand, has exposed these systems to serious security risks that did not exist before. Therefore, addressing the security and reliability of these systems is essential. In this paper, a method for modeling and evaluating the reliability of cyber-physical systems against security attacks is presented. In this method, the attacker behavior in intrusion and attack on the system is modeled along with the behavior of the system by considering defensive measures such as the use of redundant components and intrusion detection systems. Quantitative reliability assessment was performed using accessibility metrics and mean time to system failure. Finally, in an example, the applicability of the proposed method is represented.

Improving electronic warfare techniques in military operations, especially in the field of air defense, improving the resilience of radar systems against electronic warfare attacks on the battlefield as the main command and control tool in the field of air defense, will play an important role in determining the winner of the battlefield. Had. The present study aims to design and develop strategies to improve the resilience of radar systems in the electronic warfare environment and is of an applied type. The statistical sample of the research is 31 experts and professors in the field of radar and electronic warfare. Data collection is through library resources and questionnaires. The questionnaire is organized in three stages and includes confirmation of components and characteristics, ranking of strengths, weaknesses, opportunities and threats to improve the resilience of radar systems in the electronic warfare environment. 0.82) has been obtained. Data were analyzed using descriptive statistics and each of the internal and external factors were counted. Status of WT Radar Resilience Determined Finally, four main strategies for developing a strategic plan to improve the resilience of radar systems in an electronic warfare environment have been identified and prioritized.

The impact of cyberspace on human life and the employment of the obtained big data in all social, political, and security aspects of society are among the global trends. The present study seeks to answer the question concerning how governments can become aware of the trend of sensitive issues, which can result in crises, and plan against them using the big data of social media. The goal is to define an early warning system (EWS) architecture in the observation of social media for the early detection of the signals of sensitive and critical issues and assess them. Given the importance of such a system, which is among the governance requirements in the current century, along with its security sensitivities for pioneering countries, no clear information about the architecture of similar examples is available. Thus, creating such a system requires designing from scratch. Accordingly, in the present study, by taking advantage of multi-grounded theory, the early warning system's model is identified. The model is validated through fuzzy Delphi, which approves the proposed model for EWS.

Nowadays complex cyber-attacks, have made serious threats for economic and national security in counties. Unfortunately, often hackers and computer malwares are one step ahead of security systems. Therefore, instead of waiting to deal with possible threats and attacks, the same as (former cyber defense methods), we need to look for a stronger and smarter solution to eliminate that potential threat. That’s where “active cyber defense” theory arises which situational awareness is an essential part of it. Over the past few years, Experts and researchers have always been looking for an active, effective and smart situational awareness to achieve an ideal defense against today's sophisticated attacks. With the advent of active cyber defense and the proof of its effectiveness and high deterrence in improving cyber defense, achieving an ideal model of situational awareness based on the concepts and approaches of this type of defense, is one of the main research topics in this issue.
In this paper, by presenting a proposed comprehensive model of cyber situational awareness with its subdivisions based on active cyber defense strategies and techniques, in comparison with existing models, a fundamental change will be made in improving cyber defense, especially in critical and sensitive infrastructures. Some of these strategies and techniques Are Such as hack-back strategy, counter zero-day attacks, shared situational awareness, and etc. Providing a new definition of the Defender power component and increasing its coefficients by using the advantages of the proposed model as well as reviewing the evaluation results based on game theory show that the proposed comprehensive model has better performance against attackers.
