Apply attack methodology frameworks, perform incident response, and understand the incident management lifecycle to handle security incidents effectively.
Covers attack methodology frameworks including cyber kill chains, diamond model of intrusion analysis, MITRE ATT&CK, OSSTMM, and OWASP testing guide. Includes performing incident response activities such as detection, analysis, containment, eradication, and recovery. Also covers the incident management life cycle including incident response plans, tools, playbooks, tabletop exercises, training, business continuity, disaster recovery, forensic analysis, and root cause analysis.

Incident Response (IR) Management acts as the operational backbone for a Cybersecurity Analyst, providing a structured framework to address security breaches effectively. In the context of CompTIA CySA+, this process closely adheres to the NIST SP 800-61 lifecycle, comprising four distinct phases: Preparation, Detection and Analysis, Containment, Eradication, and Recovery, and Post-Incident Activity.
During the **Preparation** phase, the focus is on readiness. Analysts help establish the Computer Security Incident Response Team (CSIRT), configure monitoring tools, and develop specific playbooks and policies. The **Detection and Analysis** phase is technically intensive; analysts utilize SIEM tools, packet capture, and log analysis to distinguish between harmless anomalies and actual security incidents, performing triage to determine the scope and severity.
Once an incident is confirmed, the process moves to **Containment, Eradication, and Recovery**. Containment involves isolating affected systems to prevent lateral movement (e.g., network segmentation). Eradication eliminates the root cause (e.g., deleting malware, patching vulnerabilities), while Recovery restores systems to normal operations, often requiring validation to ensure the threat is completely removed.
Finally, **Post-Incident Activity** focuses on the 'Lessons Learned' process. Analysts must document the entire timeline, analyze the effectiveness of the response, and update procedures to strengthen future defenses. Throughout this lifecycle, CySA+ emphasizes specific forensic concepts, such as maintaining the **Chain of Custody** to ensure evidence is legally admissible, and managing communication with stakeholders. Effective IR management transforms a chaotic security event into a controlled process, minimizing downtime and reputational damage.Incident Response (IR) Management acts as the operational backbone for a Cybersecurity Analyst, providing a structured framework to address security breaches effectively.
