Hence, this chapter is intended to give a clear picture on the cyber security ecosystem and its mechanisms. The important aspects of cyber security are confidentiality, integrity and availability CIA. The CIA model is used to enhance the data security mechanisms, which are applied on security protection guidelines. Various cyber security mechanisms, cyber security policies and standards are proposed and employed to produce and achieve efficient results in data protection and privacy landscape.

Section 2.1 gives a basic introduction to cyber security. In Section 2.2, cyber security layers, securing OS, antiviruses and malwares are discussed. In Section 2.3, cyber attacks and strategies are discussed with examples. In Section 2.4, network security and, in Section 2.5, network security policies are presented in detail. In Section 2.6, disaster recovery planning and best practices are discussed. Section 2.7 concludes the chapter.
