Incident handling is a structured approach to managing and responding to security breaches or cyberattacks. It involves a set of processes and procedures designed to detect, analyze, contain, eradicate, and recover from security incidents efficiently. This systematic process ensures that an organization can minimize damage, restore normal operations quickly, and prevent future occurrences. In practice, incident handling teams follow predefined playbooks to address various types of threats, from malware infections to data breaches. Effective incident handling is crucial for maintaining business continuity, protecting sensitive data, and preserving customer trust. For instance, a company experiencing a ransomware attack would activate its incident handling plan to isolate infected systems, restore data from backups, and investigate the attack vector. It is distinct from incident response, which is a broader term that can encompass the entire lifecycle of an incident, including preparedness and post-incident activities. Incident handling is a core concept tested on exams like CompTIA Security+, CySA+, and CISSP.
