This chapter addresses the financial governance of cybersecurity within the broader ERM framework. In the current business environment, corporate activities are becoming more digital. As a result, cyber hazards are more rampant as firms become common targets for cyberattacks, resulting in significant financial losses, reputational harm, and legal liability. The process of allocating economic resources and determining expenditure priorities to support the successful adoption and upkeep of cybersecurity measures within an organization entails figuring out the extent of the risk exposure and how much money is needed to safeguard the organization’s networks, business systems, and data from online threats. Relevant governance factors addressed in cybersecurity financial management include valuation, investment, and budgeting. The presence of a well-designed cybersecurity financial governance as a tool underpinning the evaluation and ranking of cyber threats and prioritizing investments is crucial to taking cyber threats into account.
