Critical infrastructures are based on complex systems that provide vital services to the nation. The complexities of the interconnected networks, each managed by individual organisations, if not properly secured, could offer vulnerabilities that threaten other organisations’ systems that depend on their services. This thesis argues that the awareness of interdependencies among critical sectors needs to be increased. Managing and securing critical infrastructure is not isolated responsibility of a government or an individual organisation. There is a need for a strong collaboration among critical service providers of public and private organisations in protecting critical information infrastructure. Cyber exercises have been incorporated in national cyber security strategies as part of critical information infrastructure protection. However, organising a cyber exercise involved multi sectors is challenging due to the diversity of participants’ background, working environments and incidents response policies. How well the lessons learned from the cyber exercise and how it can be transferred to the participating organisations is still a looming question. In order to understand the implications of cyber exercises on what participants have learnt and how it benefits participants’ organisation, a Cyber Exercise Post Assessment (CEPA) framework was proposed in this research. The CEPA framework consists of two parts. The first part aims to investigate the lessons learnt by participants from a cyber exercise using the four levels of the Kirkpatrick Training Model to identify their perceptions on reaction, learning, behaviour and results of the exercise. The second part investigates the Organisation Cyber Resilience (OCR) of participating sectors. The framework was used to study the impact of the cyber exercise called X Maya in Malaysia. Data collected through interviews with X Maya 5 participants were coded and categorised based on four levels according to the Kirkpatrick Training Model, while online surveys distributed to ten Critical National Information Infrastructure (CNII) sectors participated in the exercise. The survey used the C-Suite Executive Checklist developed by World Economic Forum in 2012. To ensure the suitability of the tool used to investigate the OCR, a reliability test conducted on the survey items showed high internal consistency results. Finally, individual OCR scores were used to develop the OCR Maturity Model to provide the organisation cyber resilience perspectives of the ten CNII sectors.

The Scottish Legendary is a fourteenth century collection of saints’ lives in Older Scots. The prologue describes the lives as ‘merroure’ (mirror) to readers from which ‘men ma ensample ta’ (people may take example). Thus, the Legendary sets out to reveal how the reader is (mirror) thereby moving her to wish to become how she should be (exemplarity). This dissertation argues that, rather than encouraging devotion to saints along purely dogmatic lines, the Legendary transforms the reader’s selfhood by engaging her affectively, i.e. on an emotional and somatic level. By provoking the reader affectively, the text puts the reader into what Julia Kristeva has described as a ‘semiotic state’ which harks back to the reader’s or listener’s pre-cultural, pre-subjective self (Kristeva, 1984). Thus, the text disrupts the reader’s conception of herself as a complete, hermetic subjectivity, thereby dissolving the boundaries of the reader’s self. The Legendary most powerfully infiltrates the reader’s sense of self along these lines in the moments in which female saints’ bodies are tortured and dismembered. These scenes foreground the permeability of human flesh as well as its powerful influence over selfhood. Such images of abjection are, in Kristeva’s words, ‘opposed to I’; by confronting the reader with the disintegration of subjectivity in abjection, the text incites the reader to likewise experience herself as abject, i.e. disintegrable and permeable (Kristeva 1982). As I shall demonstrate, Kristeva’s psychoanalytic theory of the formation of the self offers a fruitful framework for understanding the processes of self-knowledge through reading that these saints’ lives inspire.
