In today's interconnected digital economy, organizations must navigate the benefits and risks of integrated IT infrastructures, which enhance innovation but also increase vulnerability to cyber threats. To mitigate these risks, companies need a comprehensive incident response plan that involves all key departments, including IT Infrastructure, Development, Quality Assurance, Public Relations, Legal, Human Resources, Customer Service, and Risk Management. This plan should be preemptively developed to facilitate a swift and coordinated response to incidents, ensuring that leadership support aligns with company-wide efforts. Public Relations manages external communication, Legal addresses liability and compliance, HR ensures the right personnel and policies are in place, Customer Service maintains communication with users, and Risk Management collaborates with IT to identify and mitigate potential threats. An effective incident response is not just the IT department's responsibility but requires a concerted effort across all organizational functions to proactively manage and prevent incidents.
