While today’s digitally-connected world has elevated the global economy to new heights, one cannot ignore the fact that cyberattacks and data breaches have also become a frequent problem. Research has shown that cyberattacks are on the rise among organisations, with cybercrime costing the
Australian economy over $1 billion per year. The potential for cyber threats to cost organisations millions of dollars in cleanup, lost business and reputational damage clearly demonstrates the relationship between cyber risk and business risk. With so much at stake, CISOs, the entire C-suite, and the Board require insight into cyber exposure in the same way as other risks.
This practical guide will help CISOs communicate cyber risk to the C-suite and board of directors in a way that fosters a business-based dialogue for better, more informed decision making that focuses on maximising risk reduction.
Focus on critical risks
There’s a tendency to mistakenly follow a traditional “check-the-box” approach to addressing every risk. This is akin to chasing your own tail because it provides no visibility of actual risks and consumes valuable resources and time on vulnerabilities that have a low likelihood of being exploited.
Mature organisations have evolved from this archaic approach toward risk-based vulnerability management. Utilising threat intelligence, vulnerability research, and probability data allows a CISO to focus on critical risks. These are vulnerabilities that are actually at high risk of being exploited.
A 2019 study by McKinsey Consulting found that risk-based vulnerability management allows companies a potential risk reduction of 7.5 times above their original program, at no added cost.
Present the board with clear answers
Let’s be honest, when the C-suite or board of directors asks a CISO, “How secure are we?” the last thing they want is a long-winded answer. They expect insight into cyber risk in the same way as other operational areas, and with the same accuracy and predictability.
Therefore, this is an opportunity for the CISO to present a measurable view of the organisation’s cyber risk exposure using internal and external comparative benchmarks. Consider using concise and understandable language suitable to guide strategic leadership decision-making by the board.
Cyberattacks have the ability to destroy an organisation’s reputation or competitive advantage, both of which are critical to the health of the business. Therefore, CISOs must be prepared to effectively communicate this message to the board and clearly explain how this risk is being addressed across the business unit, asset, and geo-location.
Channel resources appropriately
An effective CISO should measure success by risk reduction, not milestones or tool deployment. In a crisis, it is critical to know what controls are really effective. Demand assurance that the security team is focused on identifying and reducing critical vulnerabilities that pose a business risk.
Remediation actions should be prioritised to reduce the organisation’s cyber exposure. A CISO should drill down into specific vulnerabilities or assets to identify and support controls that are more effective and truly reduce risk.
Make cybersecurity risk management a living strategy
Consider meeting with the C-suite frequently to review risk priorities and strategy. Without a solid internal governance structure, organisations will have trouble building any success.
Oversight of security may be led by the CISO, but the entire C-suite should drive a cross-team leadership approach. Security is a team effort and a moving process. It is linked to every part of business operations and therefore requires a cross-team governance structure to support the program and resolve critical decisions.
This also assures that the security strategy will be a flexible, living strategy, with critical internal leadership support. Utilise the insights from a risk-based vulnerability management approach to adjust strategy and investment based on critical vulnerabilities that pose the greatest business risk.
Successfully get ahead of attackers
In the fast-moving environment of cybersecurity, where the entire business may be at risk, organisations need to understand where to focus resources and investment to maximise their cyber risk reduction. At the same time, C-suite and boards of directors require a means to objectively measure cyber exposure. This should be in non-technical terms and allow business leaders to understand how they compare to their industry peers or other organisations with best-in-class security.
