An action plan in cybersecurity is a formally documented strategy that outlines specific steps to address security objectives, mitigate identified risks, or respond to incidents. This structured document emerges from security audits, vulnerability assessments, or threat analysis, translating findings into concrete interventions that strengthen an organization's defensive capabilities.

The plan details precise tasks, assigns responsibilities to designated individuals or teams, establishes completion timelines, and allocates necessary resources. It includes defined metrics for tracking progress and measuring success, ensuring accountability throughout implementation. Regular review and adaptation keep the action plan relevant against evolving threats, making it a dynamic blueprint for continuous security improvement and regulatory compliance.
