Scope: Determine which systems, applications, and infrastructure components to monitor. 2. Identify Key Logs System Logs: OS-level logs (e.g., Linux syslog, Windows Event Viewer). Application Logs: Logs from critical applications, databases, and middleware. Network Logs: Firewall, IDS/IPS, and router logs. Security Logs: Authentication events, access control logs, and SIEM system outputs. Cloud Logs: Logs from cloud services like AWS Cloud Watch, Azure Monitor, or GCP Logging. 3.
