The ultimate responsibility of cyber security risk management lies with CISO. While cybersecurity is mostly related to attacks on IT assets, it beyond IT to OT as well. CISOs in many organisations also are responsible for managing potential cyber threats due to vulnerabilities that points in critical infra structure of Operational Technology (OT) that controls it.
Ideally CIO and CISO roles are generally peers in matured organisations for CISOs function to be more effectively. Typically, CIO reports into CFO or CEO depending upon organisation structure. CISO reports into CRO (Chief Risk Officer) or directly into CEO.
