The role of the chief information security officer in the management of IT security

Abstract

Purpose The aim of this study is to advance research on the position of the CISO by investigating the role that CISOs play before and after an IT security breach. There is a dearth of academic research literature on the role of a chief information security officer (CISO) in the management of Information Technology (IT) security. The limited research literature exists despite the increasing number and complexity of IT security breaches that lead to significant erosions in business value. Design/methodology/approach The study makes use of content analysis and agency theory to explore a sample of US firms that experienced IT security breaches between 2009 and 2015 and how these firms reacted to the IT security breaches. Findings The results indicate that following the IT security breaches, a number of the impacted firms adopted a reactive plan that entailed a re-organization of the existing IT security strategy and the hiring of a CISO. Also, there is no consensus on the CISO reporting structure since most of the firms that hired a CISO for the first time had the CISO report either to the Chief Executive Officer or Chief Information Officer. Research limitations/implications The findings will inform researchers, IT educators and industry practitioners on the roles of CISOs as well as advance research on how to mitigate IT security vulnerabilities. Originality/value The need for research that advances an understanding of how to effectively manage the security of IT resources is timely and is driven by the growing frequency and sophistication of the IT security breaches as well as the significant direct and indirect costs incurred by both the affected firms and their stakeholders.

The “New” Private Security Industry, the Private Policing of Cyberspace and the Regulatory Questions

“…Organizations have sought to protect themselves from the growing problem of cybercrime by developing their own cybersecurity structures and purchasing the services from the "new" private security industry to better protect themselves. In most large organizations, there are cybersecurity structures led by what are generally called chief information security officers (CISOs) (Karanja, 2017). These run departments of various functions whose role is to prevent and deal with most cybercrimes against the organization.…”

From Degree to Chief Information Security Officer (CISO): A Framework for Consideration

“…Soon the need for a person in charge of the security of the organization's information system was apparent. However, there was not a clear understanding as to the exact role and responsibilities of the officer in charge [9].…”

“…Typically, an organization is led by the Chief Executive Officer (CEO), who is in charge of corporate governance, as well as the major decision making processes, structures and systems [9]. The CEO's main goal is to ensure the success of the organization for the investors and sponsors.…”

“…The CISO is in charge of the security strategy and the security programs while working with all of the business units to ensure alignment. Karanja [9] reported that there is a lack of consensus on the security reporting structure. The most common person that the CISO reported to was the CRO or Legal Officer, followed by the Chief Operating Officer (COO).…”

“…Karanja [9] explains that the reporting structures need to have clear roles and responsibilities. Additionally, each member of the C-Suite must respect and understand these roles and responsibilities.…”
