This chapter aims to identify and analyse the ethical problems of security, particularly cyber and digital threats. The concepts of security and safety are defined based on existing literature. The chapter addresses the key results and research gaps in the field (i.e., security issues in different areas) and future challenges, both theoretical and empirical. Moreover, the discussion is linked to an analysis of the relationship between utilitarian ethics and deontological ethics, which brings a new perspective to the debate on security ethics in general and cybersecurity. Finally, comprehensive security and absolute safety ideas are discussed, which sheds new light on the complexity of security concerns.

Cloud computing is recently emerging technology, which provides a way to access computing resources over Internet on demand and pay per use basis. Cloud computing is a paradigm that enable access to shared pool of resources efficiently, which are managed by third party cloud service providers. Despite of various advantages of cloud computing security is the biggest threat. This chapter describes various security concerns in cloud computing. The clouds are subject to traditional data confidentiality, integrity, availability and various privacy issues. This chapter comprises various security issues at different levels in environment that includes infrastructure level security, data level and storage security. It also deals with the concept of Identity and Access Control mechanism.

Security Issues

Cloud is considered as future of Information Technology. User can utilized the cloud on pay-as-you use basis. But many organizations are stringent about the adoption of cloud computing due to their concern regarding the security of the stored data. Therefore, issues related to security of data in the cloud have become very vital. Data security involves encrypting the data and ensuring that suitable policies are imposed for sharing those data. There are several data security issues which need to be addressed. These issues are: data integrity, data intrusion, service availability, confidentiality and non-repudiation. Many schemes have been proposed for ensuring data security in cloud environment. But the existing schemes lag in fulfilling all these data security issues. In this chapter, a new Third Party Auditor based scheme has been proposed for secured storage and retrieval of client's data to and from the cloud service provider. The scheme has been analysed and compared with some of the existing schemes with respect to the security issues. From the analysis and comparison it can be observed that the proposed scheme performs better than the existing schemes.

Security Standards

Data security is a major concern in cloud computing environments as they provide much scope for intruders to attack. Data centres in cloud environments hold valid information that end-users would conventionally have stored on their computers. Moving information towards centralised services may have an adverse effect on the security of users’ interactions with files kept in cloud cupboard spaces[1], for example accidental or deliberate alterations or deletions of information from the cloud server by the Cloud Service Provider (CSP). This necessitates the deployment of some sort of mechanism to ensure the safety of information integrity[2]. Public sector organisations have much to gain by adopting a cloud computing approach to service delivery in their ICT environments. However, these benefits must be reaped without compromising core requirements and institutional values.This paper focuses on the security issues that may arise when public sector organisations consider transitioning to an Open Source Software (OSS) Infrastructure as a Service (IaaS) Cloud Infrastructure (OpenStack), although the same issues are likely to be found in other OSS cloud computing software like Apache CloudStack[3], Eucalyptus[4], and OpenNebula[5]. We examine legal implications, regulatory and standards compliance, new attack vectors resulting from vulnerabilities coming from virtualisation technologies, data integrity issues such as encryption and access controls, and security checks to be performed on the services prior to their movement to the cloud. In addition, some of the most important security threats in cloud computing are presented, followed by key recommendations on how to address them, namely security standards and certifications, service provider auditing, secure APIs, transport layer protection, authentication and encryption key management, and cloud service agreements.

As information and processes are migrating to the cloud, Cloud Computing is drastically changing IT professionals’ working environment. Cloud Computing solves many problems of conventional computing. However, the new technology has also created new challenges such as data security, data ownership and trans-code data storage. We discussed about Cloud computing security issues, mechanism, challenges that Cloud service providers and consumers face during Cloud engineering. Based on concerning of security issues and challenges, we proposed several encryption algorithms to make cloud data secure and invulnerable. We made comparisons among DES, AES, RSA and ECC algorithms to find combinatorial optimization solutions, which fit Cloud environment well for making cloud data secure and not to be hacked by attackers.

Cloud computing is a way to increase the capacity or add capabilities dynamically without investing in new infrastructure, training new personnel, or licensing new software. As information exchange plays an important role in today’s life, information security becomes more important. This paper is focused on the security issues of cloud computing and techniques to overcome the data security issue. Before analyzing the security issues, the definition of cloud computing and brief discussion to under cloud computing is presented. The various components that affect the security of the cloud and the problems faced by cloud service provider have been discussed in this paper.
