'Network Security is mostly concerned with protecting the data accessibility and usability from unauthorised users'. Thus, security policies must be balanced according to various interrelated goals that reflect the critical nature of information storage, processing and transmission. a) Suppose that you were making the case of adapting a comprehensive security policy in your organisation to secure network accessibility, communication and resources. Confidentiality, Integrity and availability are your main security considerations. Discuss how it is possible to have integrity without confidentiality and vice versa? b) Distinguish between Authorisation and Authentication. Discuss which happens first in Network Management System. Justify your answer. c) Deploying the General Data Protection Regulation (GDPR) law in the European Union has ensured data privacy. Therefore, companies are required to 'implement appropriate technical and organisational measures'. As a Network Manager you are required to implement data protection safeguards into products and services from the earliest stages of development to protect users' data. These safeguards must be appropriate to the degree of risk associated with the data held. Discuss the key points you need to consider in deploying these safeguards.
