Communication is a key factor for the effectiveness of cybersecurity incident response, as it ensures that all relevant parties are informed, coordinated, and aligned on the incident status, impact, actions, and responsibilities. Communication also helps to maintain trust, confidence, and transparency among the stakeholders, such as senior management, business units, customers, regulators, law enforcement, and media.

Enterprise goals are the most critical input because policies, standards, and procedures must align with and support the organization's overall objectives to ensure security efforts are relevant and effective.

Senior management engagement is most effectively achieved when information security risks are clearly connected to real, tangible business consequences. A major breach at a competitor (B) provides a credible, industry-relevant example that demonstrates potential financial, operational, reputational, and regulatory impacts in a way executives readily understand. While BIA results (A), audit findings (C), and cost-benefit analyses (D) are important inputs, they are often abstract or internally focused. CISM guidance emphasizes that executive support is strongest when security messaging is business-driven, externally validated, and tied to strategic risk awareness. A peer breach highlights that the threat is realistic, imminent, and applicable to the organization's context, which increases urgency and executive buy-in for the security strategy.
