Cyber Incident Response is the structured process an organization follows to detect, respond to, manage, and recover from cybersecurity incidents such as malware infections, data breaches, ransomware attacks, insider threats, and more.
It aims to:
- Limit damage
- Reduce recovery time and cost
- Maintain business continuity
- Meet regulatory and legal obligations
Key Components of Cyber Incident Response
1. Preparation
- Develop an Incident Response Plan (IRP)
- Set up incident response teams, tools, and playbooks
- Train staff to recognize and report incidents
2. Detection & Identification
- Use systems like SIEM, EDR, IDS/IPS to detect anomalies
- Confirm whether the event is a real security incident
3. Containment
- Isolate affected systems to prevent spread
- Block malicious IPs, disable compromised accounts
4. Eradication
- Remove malware, patch vulnerabilities, clean up compromised systems
5. Recovery
- Restore incident response tools, systems, and operations
- Monitor for signs of reinfection
6. Lessons Learned
- Conduct a post-incident review
- Update security policies, detection rules, and training
Common Tools Used in Cyber Incident Response
- SIEM (e.g., Splunk, IBM QRadar) – for log aggregation and alerting
- EDR/XDR (e.g., CrowdStrike, SentinelOne) – for endpoint detection and response
- SOAR (e.g., Cortex XSOAR) – for automation and playbook execution
- Forensics tools (e.g., EnCase, Velociraptor) – for root cause analysis
- Threat Intelligence Platforms – for context and enrichment
Benefits of Effective Cyber Incident Response
- Faster containment of threats
- Reduced financial and reputational damage
- Improved compliance (e.g., GDPR, HIPAA)
- Stronger organizational resilience
