Study Notes
Incident Response Process
- Pay attention to indicators of compromise (IoCs) during security events.
- Utilize log analysis and security monitoring to enhance incident detection.
- Train staff on incident reporting and awareness to improve response times.
Analysis Phase
- Analyze identified potential incidents by correlating related events and assessing their impact.
- Understanding the target of the incident and its overall consequences is crucial for effective response.
Containment Strategy
- Take immediate action to contain identified incidents and prevent escalation or further damage.
- Isolation methods may include quarantine—restricting affected devices from accessing the network.
Eradication Stage
- Focus on removing all artifacts related to the incident, which may require rebuilding systems from backups.
- Achieve complete eradication to ensure the incident is fully resolved.
Recovery Phase
- Restore normal operations by bringing systems and services back online while ensuring weaknesses are fixed.
- Conduct post-incident analysis to prevent recurrence of the same incident.
Lessons Learned Sessions
- Organize sessions to analyze incidents, fostering organizational improvement and preventing repeat mistakes.
Types of Indicators
- Recognize that any behavior exhibited by an attacker can serve as an IoC.
- Published/documented indicators are shared through threat feeds and information-sharing organizations.
Incident Response Frameworks
- Utilize common terminology and frameworks, like MITRE ATT&CK, to categorize and document attack techniques.
- Familiarize with the entirety of the threat life cycle for better incident handling.
Monitoring Computing Resources
- Understand key monitoring types: systems, applications, and infrastructure.
- Collect logs for system health and performance; application monitoring varies based on specific applications used.
Role of SIEM Systems
- Centralize security monitoring through security information and event management (SIEM) systems.
- SIEM systems collect log data from multiple sources, allowing for correlation and advanced analysis.
SIEM Features
- SIEM tools can alert, report, and respond to potential security incidents and user behavior analysis.
- Capable of performing packet capture for in-depth incident investigation and correlating various log sources.
SIEM Dashboard Utility
- Dashboards provide visual representation of critical security data to help analysts identify abnormalities.
- Configure dashboards to focus on key metrics and trends relevant to organizational security needs.
Sensor Deployment
- Sensors gather additional data for SIEMs and are critical for environments that generate large volumes of unique data.
- Proper placement and security of sensors are essential to protect data acquisition efforts from compromise.
Managing Sensitivity and Alerts
- Adjust sensitivity and thresholds in SIEM systems to control the volume of alerts and minimize noise.
- Implement filtering rules to ensure that critical alerts are prioritized for response.
