CISO
The person responsible for an organisation's cybersecurity: they set the strategy and steer the protection.
The RSSI (in English, CISO) is the person tasked with defining and steering an organisation's IT security. Their role is broad: governance, risk management, awareness, crisis management, well beyond the technical side. To stay independent, they should not report to the IT department they partly oversee.
