Abstract

Organisations are facing sophisticated and advanced persistent threats (APT) that are targeting sensitive information assets. Any form of cyber-presence can be typically attacked by adversaries, and the motives of such attacks are context dependent. Besides, users and organisations are prone to software vulnerabilities, misconfigurations, outdated systems and several other systemic deficiencies which can be leveraged to compromise enterprise assets and gain an initial foothold within an organisation network. The aim of the paper is to develop a flexible and generally comprehensive organisational strategy to defend against the massive increase in cyberattacks, in order to protect the strategic business objectives of an organisation and keep an alignment between business objectives and security. Moreover, this paper reflects on the work undertaken by multiple teams within the chosen case study organisation to enhance the cybersecurity.
