A cyber incident response plan is a comprehensive set of guidelines and procedures designed to help organizations effectively respond to security incidents involving their computer systems and networks. The plan outlines how to identify, contain, eradicate, and recover from cyber incidents. It also includes details on how to coordinate with external parties, such as law enforcement agencies, and how to communicate with stakeholders, such as customers and employees. An effective cyber incident response plan should be regularly tested and updated to ensure it remains relevant and effective in the face of emerging cyber threats.
