Incident Response Procedure
NextSOC follows this incident response procedure, which systematically address and mitigate cyber incidents, taking into account risk assessments, severity levels, and lessons learned for continuous improvement in their cybersecurity posture.
Objective: Effectively respond to cyber incidents while considering risk and severity levels.
Incident Identification:
- Utilize monitoring systems, alerts, and user reports to identify potential cyber incidents.
- Categorize the incident based on the predefined categories (A to G).
Risk Assessment:
- Evaluate the risk associated with the incident using the risk matrix.
- Consider the potential impact and likelihood of the incident occurring.
Severity Determination:
- Assess the severity of the incident based on the risk matrix evaluation.
- Categorize the incident as Critical, Major, Moderate, Minor, or Insignificant.
Incident Analysis:
- Investigate the incident to gather detailed information about its nature and scope.
- Identify the specific subtype within the assigned category (e.g., malware attack, phishing attempt).
Containment and Mitigation:
- Implement immediate containment measures to prevent further damage or unauthorized access.
- Mitigate the impact of the incident based on its severity level.
Communication:
- Notify relevant stakeholders, including IT teams, management, and legal, based on the severity of the incident.
- Maintain transparent and timely communication throughout the incident response process.
Documentation:
- Record incident details, risk assessments, and severity levels in a centralized incident management system.
- Document actions taken during the containment and mitigation phases.
Notification to Authorities (if applicable):
- If required by regulations or the severity of the incident, notify appropriate authorities or regulatory bodies.
Recovery:
- Execute recovery procedures to restore affected systems and services to normal operation.
- Monitor for any residual effects and ensure the incident is fully resolved.
Post-Incident Review:
- Conduct a thorough post-incident analysis to identify root causes, lessons learned, and areas for improvement.
- Update incident response procedures and preventive measures based on the analysis.
