Incident response techniques are the established procedures and actions organizations follow to manage and mitigate the impact of cybersecurity breaches or attacks. These techniques involve a structured approach encompassing preparation, identification, containment, eradication, recovery, and lessons learned to minimize damage and restore normal operations. In practice, they guide security teams through a crisis, ensuring a coordinated and effective reaction to threats. Understanding these techniques is crucial for protecting sensitive data, maintaining business continuity, and preserving customer trust. For instance, a common technique is network segmentation to isolate an infected system, preventing malware from spreading. This differs from incident detection, which focuses solely on identifying an event rather than the subsequent management steps. These techniques are fundamental to certifications like CompTIA Security+, CySA+, and CISSP.
