Which step is NOT recommended for organizations responding to incidents impacting external actors?

Organizations responding to incidents that impact external actors need to ensure effective communication and cooperation. Providing supply chain partners with detailed data on past incident impacts may not be recommended due to several reasons. Sharing comprehensive historical data about past incidents could lead to security and privacy concerns, as this information might contain sensitive details that could be exploited by malicious actors. Additionally, the relevance of past incidents may diminish over time, and focusing on current risk and threat assessments would be more beneficial than analyzing historical data.

In contrast, preparing supply chain plans-of-action, maintaining contact information databases for external actors, and establishing agreements for notification requirements are all proactive steps that enhance preparedness and response capabilities. These measures ensure that the organization can quickly and effectively communicate with external partners and manage potential risks. Such strategies focus on building resilience and fostering collaboration, which are crucial in incident management.
