Abstract  Nowadays, cloud computing is the preferred choice of any organization based on information and communication technology due to its flexible services and outstanding pay-as-you-go features. Some cloud-based networks face various security challenges due to the lack of fixed infrastructure and centralized management. However, the security and privacy of cloud computing systems is a fundamental problem of cloud computing due to their distributed architecture and vulnerability to unwanted inputs. The role of unwanted attack detection systems in cloud security is very important because it acts as a preventive security layer and, in addition to identifying known attacks, can detect many unknown attacks. In this article, we intend to review these systems and describe approaches to deal with the challenge of intrusion into cloud computing services.

Therefore, addressing these challenges, along with leveraging new technologies, will be the key to success in the future development of blockchain. This paper can be used as a reference for further research in the field of blockchain security and the development of related technologies.

Abstract As a smart and effective technology, the Internet of Things (IoT) plays a very important role in today's technology-driven world. This technology refers to a set of computer and technology-driven communications and interactions such as sensors, processing units, software and hardware with other devices and systems, that are connected and linked via the Internet or other communication networks. On the other hand, blockchain is a decentralized and distributed ledger that records transactions on many computers. This structure ensures that no single entity can access the entire chain to commit fraud. Each block in the chain contains a list of transactions, a time stamp and a cryptographic hash of the previous block, so each record created is unchangeable in a secure way. Blockchain technology, as one of the great innovations of the digital world, has been applied in many areas, including cybersecurity. Security is one of the fundamental challenges in the field of IoT, which can be enhanced and improved through blockchain. The purpose of this research is to analyze the solutions to improve security and privacy and to apply it in creating a privacy monitoring system in the Internet of Things based on blockchain technology. Finally, blockchain, with its unique features, can be an important tool in strengthening the security of the IoT against various threats and reducing risks. Using this technology in areas such as data protection, preventing information manipulation, and increasing the security of cloud systems can help reduce threats and improve digital security. Although there are challenges in the path of blockchain adoption and implementation, its benefits, especially in this area, are very significant.

Abstract Blockchain is a new technology whose purpose is to store and transfer any type of data in a decentralized manner. In this system, nodes are responsible for confirming and registering transactions, each of these nodes are distributed around the world and use different algorithms to perform their tasks correctly. In blockchain technology, data security has a very high value, and this technology can make our private information more secure and prevent the disclosure of this information. Blockchain security is ensured through various mechanisms, including advanced encryption techniques and mathematical models of behavior and decision making. Blockchain technology is the basic structure of most cryptosystems and what prevents the repetition or destruction of this type of digital currency and interference in the cycle of purchasing digital currency. In this article, in particular, blockchain security in the field of e-commerce is examined and cyber attacks against blockchain and challenges in this field are introduced.

Abstract Cloud computing is a processing model that has attracted the attention of researchers due to its flexibility, rapid expansion and low cost, and it provides the shared use of services without the need for ownership and management of resources in the network environment. On the other hand, cloud computing is a pool of virtual computer resources. Resource virtualization in cloud computing allows heavy tasks to be performed faster and with less dependence on physical resources. Although cloud computing has become very popular among users, security problems are considered as a big obstacle for users to use cloud computing systems. Data security and virtualization security are two important security issues in cloud computing. In this article, we examine the dimensions of virtualization security in cloud computing environments.

Abstract Nowadays, due to the large amount of information and the need of rapid processing, the need for computers with up-to-date and efficient operating systems with high processing power is felt. During the last decades, progress in the field of information technology has made available fast distribution systems. Distributed systems are one of the best solutions to achieve the above goal. By placing computer systems on the platform of the distribution network, it is possible to create a high processing power, whose complexity and organization are hidden from the eyes of users and in addition, it brings us the availability of resources and scalability. Securing the core of distributed operating systems is a necessity that can help improve the security of information technology in distributed network environments. In order to fundamentally implement this process, it is necessary to create an expert security team. Also, in addition to the technical review and the implementation of protection settings and access controls, there is a need to develop new methods and tools to study the sequence of certain or possible protection operations in the core of distributed operating systems. In this article, we are going to examine the security aspects in the core of distributed operating systems.

Abstract  The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Internet of Things security is a subset of cybersecurity that focuses on protecting, monitoring and remediating threats related to the Internet of Things, or the network of connected devices that collect, store, and share data over the Internet. IoT security challenges can be very controversial because many IoT devices are not built with strong security. Security risk in IoT is critical because the sensitivity of the data IoT devices collect and store, as well as the systems they manage, is much greater than traditional personal network security strategies. In this article, we discuss the functions of the security aspects of the Internet of Things.

Abstract Cloud computing is a new computing model that includes network computing, distributed computing; Parallel computing, virtualization technology, applied and auxiliary computing and other computer technologies originated. The security issue of cloud computing is very important and this issue can prevent the rapid development of cloud computing. If a security problem occurs for cloud computing, it can no longer be used on a large scale, and its rapid and widespread use by people will decrease. The two security issues of data privacy and service availability are among the issues that are raised about the security issue of cloud computing and are among its key security issues. Applying a security method alone cannot solve the security problem of cloud computing; Rather, a wide range of technologies, as well as new technologies and strategies, must be used together to protect the entire cloud computing system. This article introduces some fundamental cloud computing systems and the problem of security feasibility of cloud computing and existing risks and its related strategy as challenges, opportunities and perspectives of this field, according to the ideas and characteristics of cloud computing.
