the ever - increasing growth of cyberspace and its attractiveness in this space has led to  a significant portion of the daily activities of Citizens,  businesses, recreation and entertainment to the  atmosphere;  cyber terrorism is one of  these strategic threats which has faced  many countries such as the islamic  republic  of iran in recent years .the strategic  documents  of the leading  countries  indicate that this threat is the  first priority of the threats of these countries so that they allocate a lot of resources to deal with it .in this paper , after studying the relevant backgrounds of terrorism and cyber  terrorism , its position among other cyber - cyber  threats has  been explained and finally the definition of the researcher - made cyber - terrorism has been explained and finally the definition of threats , methods of threat assessment , management approaches and by using them , the conceptual model is drawn and the final model is presented .

Today, with the advent of software defined networking (SDN) in organizations, the architecture of SDN has replaced the traditional networking which has gained benefits in organization management as well.By separating data control section from data transfer section, SDN provides numerous advantages such as better controllability, dynamic management, and optimal use of bandwidth and network resources; however, it is still vulnerable to denial of service attacks.This way, invaders would be able to overrun software and hardware resources of the network, and they could interrupt user’s accessibility to these services.That’s why, we have simulated and inspected denial of service attacks and different ways to confront these perils in software defined networking. Plus, in the proposed algorithm, we have used Pearson correlation coefficient in order to recognize these types of attacks.Then, we have used MiniNet simulator and OpenDayLight controller to assess the proposed algorithm; and finally, we have represented the competence and advantages of the proposed algorithm in respect to the previous algorithm.

The emerging technology of the Internet of Things provides the ability to send and receive data between different objects through communication networks and can be the source of tremendous changes in military equipment and enhancing the efficiency of defense departments. The command and control system is one of the most important areas of defense systems that can be transformed by Internet of Things technology. Command and control is the planning, guidance, coordination and control of the operations based on the effective operation of the operational scenario, so in order to achieve the best result, complete, accurate and timely information is essential. On the other hand, utilizing the Internet of Things technology allows the commanders to get the most accurate and accurate information about the battle scene in the shortest time. This research was conducted with the aim of examining the requirements for exploiting the Internet of Things technology in the command and control system.This study is a descriptive and qualitative descriptive in terms of the purpose of the applied type and in terms of descriptive and qualitative method, using content analysis method. The statistical population of the study was people who were expert and knowledgeable about cyber space and command and control issues, that 30 person of them were selected purposefully and a questionnaire was conducted about them.The results show that in order to use the Internet of Things in the command and control system, it should be in three layers of the program, reception, network and infrastructure, in order to upgrade and localize the software, use dynamic security patches, ensure the health of the microprocessors, provide security of the sensors, utilizing cryptography, providing network availability, matching protocols, network scalability, creating a Private cloud, providing physical protection and energy supply of sensors.

cyber resilience is the ability of the system to return to the initial situation after an unexpected event .in the introduction of this article , the definition of resilience and resilience based on different references has been discussed and in the following the frameworks , models and issues related to cyber resilience have been mentioned . a number of frameworks , models , and topics related to the resilience of cyber - resilience discussed in this paper are as follows :Cyber ​​security model with security strategy, care and resilience (return), Standard 27001, Resilience of infrastructure, plan for resilience to resilience, cyber - resilience engineering framework, cyber resilience keys, top issues for cyber resilience and… at the end of the article , the application of the MITRE cyber - resilience engineering framework and the سایبری security framework is proposed by adding new and innovative methods to create cyber resilience in the organization .

Three important factors shape the organizational structure of a terrorist group, its popular support, and its access to the area under its control - to the counterintelligence activities of terrorist organizations. Terrorist groups that invest in public support are more sensitive to the growth of video-sharing and user-centric media on the Internet. Leaders of terrorist groups often spend a lot of time promoting their image among the people in order to gain popularity for themselves., Raise the morale of their group and attract financial and human support. This article will try to answer the main question: "What is the strategy of the Takfiri terrorist group in using cyberspace? At what level can their activities be evaluated? Our hypothesis is that this (activity in cyberspace) ) As the main strategy, Has transformed them from an organizational framework that had limited facilities and capabilities to a broad stream that is becoming more and more developed. Therefore, cyberspace is the most important tool in the field of propaganda of Takfiri terrorist thinking, its impact on the promotion of Al-Nasr strategy in fear.Recruitment, organization and deployment of forces that through a survey method as well as analysis of the content of first-hand texts related to al-Qaeda will carefully analyze the research question and hypothesis and consider counter-terrorism strategies and thwart cyber-terrorism measures. puts

Two real factors in designing defense industrial control systems, utilizing resources and quality of defense products can be made worse by using these services to use the basement shade to access various shade facilities in the production project and management systems. Has been commercially defensive. Using a defensive control management system for cyber highlighting, as a guest of support, it is possible for you to be able to manage your system and be able to resize and return to your current situation when you resize. Destroy. Cyber threats can be made.In this study, to evaluate and analyze vulnerabilities in the resilience of defense industrial control systems against cyber threats as one of the main steps in cyber resilience, the model of assessing and analyzing vulnerabilities in resilience of defense industrial control systems against threats Cyber-based Model Integration Capability Maturity Model, Systematic Process Improvement Model, is presented for three levels of industrial control systems including management level, control level and defense industrial control system operation level. Vulnerability Assessment and Analysis Model for Resilience of Defense Industrial Control Systems against Cyber Threats at 5 Maturity Levels and Three Main Dimensions of Industrial Control Systems are presented and 51 indicators are presented in total.
