Triage Event (something happened) Incident (Violation of policy, law or regulation) Cyber triage best practices include: establishing standardized protocols, leveraging threat intelligence to prioritize alerts, automating repetitive tasks, incorporating AI and machine learning for faster analysis, regularly updating detection rules, training analysts on emerging threats, and continuously improving processes to adapt to evolving cyber threats
Triage Event (something happened) Incident (Violation of policy, law or regulation) Use both human and technical mechanisms to detect incidents Need partners who can alert you of incidents Need a monitoring capability Need a process to review logs
2) Determine root cause Leverage your resources Leverage subject matter experts Review holistically CVE database How did it start?
3) Assess severity/impact Assess what systems are affected Assess what business processes are affected
