In today’s rapidly evolving digital banking landscape, cybersecurity has become a board-level business priority. Yet one fundamental question remains: Can a Bank CISO take complete ownership of all cyber risks?
The answer is clearly NO.
While the CISO is responsible for leading the cybersecurity function, cyber risk is ultimately a shared organizational responsibility.
A CISO can establish security strategies, policies, controls, monitoring mechanisms, and incident-response frameworks. However, cyber risks originate across multiple dimensions—including technology, people, processes, third parties, business decisions, and customer behavior. A security function cannot independently control all these factors with precision.
Consider a business unit launching a new digital product, a technology team deploying an application, or a procurement team onboarding a third-party service provider. Each decision can introduce new cyber risk. The CISO can assess the risk, provide guidance, challenge assumptions, and establish security requirements. However, the ultimate ownership of that risk often rests with the relevant business or process owner.
This distinction between risk ownership and risk management is critical.
The CISO should be accountable for the effectiveness of the cybersecurity program, while business leaders should own the risks arising from their respective areas of operation. The Board and senior management, meanwhile, have overall responsibility for ensuring that the bank’s cyber-risk appetite is clearly defined, understood, and appropriately governed.
The traditional model of treating cybersecurity as an “IT problem” is therefore no longer sustainable.
Every employee who handles sensitive information, every developer who writes code, every manager who approves a technology solution, and every third party that accesses bank systems can influence the institution’s cyber-risk profile.
An established bank should consequently adopt a shared-responsibility model. The CISO should act as the security leader, trusted advisor, challenger, and coordinator—not as the sole owner of every cyber risk.
Clear roles, accountability matrices, risk-acceptance processes, and escalation mechanisms should establish who owns each risk, who is responsible for mitigating it, and who has the authority to accept it when mitigation is not feasible.
This approach also prevents the CISO from becoming a convenient “single point of accountability” whenever a cyber incident occurs. Holding the CISO responsible for risks that were knowingly accepted, created, or retained by other functions can weaken governance rather than strengthen it.
The objective should not be to determine who is to blame after an incident, but to establish who is accountable before the incident happens.
Ultimately, cybersecurity is much like financial or operational risk: it cannot be delegated entirely to a single function.
The CISO should own the cybersecurity capability, framework, and assurance mechanisms, while cyber risk itself should remain distributed among the appropriate business, technology, process, and third-party owners.
For banks seeking true cyber resilience, the question should therefore evolve from:
“Is the CISO responsible for cyber risk?” to: “Does every risk owner understand, accept, and actively manage their responsibility for cyber risk?”
That shift—from CISO ownership to enterprise accountability—is essential for building a genuinely resilient digital banking service.
