Effective risk management cannot occur in an operational vacuum. ISO/IEC 27005:2022 emphasises that communication and consultation constitute a continuous, iterative process for sharing information and engaging in dialogue with internal and external interested parties about the nature, significance, and treatment of information security risks. The primary objective is to achieve a documented agreement on risk management by establishing bidirectional communication channels among risk owners, top management, and personnel responsible for implementing ISMS controls.

Risk ownership is frequently a point of friction within modern enterprises. Individuals may be reluctant to acknowledge accountability, or ownership may be deliberately obfuscated in highly decentralised, matrixed organisations. Therefore, a formalised communication procedure is vital to definitively inform personnel of their risk ownership status and the specific accountabilities tied to that designation. Risk owners must understand the risk scenarios, approve the risk treatment plans, and make the final, informed executive decision on whether to accept any residual risk after controls are implemented.

Furthermore, perceptions of risk vary drastically across an organisation due to differences in assumptions, operational needs, and the cognitive biases discussed previously. Communication must be tailored to address these varying perceptions, ensuring that stakeholders understand the underlying rationale behind risk acceptance decisions and the calculation of risk criteria. By involving stakeholders early in the risk assessment design phase and as methodologies are selected, organisations increase the likelihood that findings will be accepted and treatment plans supported. Interested parties are fundamentally less likely to question the outcomes of processes that they have helped design, effectively building executive commitment and securing necessary resources.

However, the distribution of risk intelligence must be carefully managed. Since risk assessments specify the vulnerabilities and potential failure points of an organisation's critical infrastructure, communication should be strictly controlled on a "need-to-know" basis. The aim is to prevent sensitive weaknesses from being disclosed to internal personnel who do not need the information or to external entities, thereby unintentionally increasing the risk of exploitation. Organisations are advised to establish dedicated risk committees to facilitate secure discussion of prioritisation and to develop specialised communication plans for both routine operations and crisis management.
