Ensuring business continuity and minimizing downtime are critical aspects of security operations. Setting up HA for Disaster Recovery in FortiSIEM helps organizations maintain a resilient security infrastructure. Here’s an in-depth look at the HA-DR setup and troubleshooting techniques to ensure seamless failover.
?? Step 1: Setting Up HA for DR Supervisors and Workers
High Availability in FortiSIEM consists of Supervisors and Workers that must be synchronized to ensure real-time failover.
? Primary Tasks:
?? Configure Supervisor Nodes in HA mode (Active-Passive)
?? Set up Worker Nodes in HA mode for event processing redundancy
?? Define VIP (Virtual IP) for Supervisor nodes for seamless failover
?? Enable Database Replication to ensure log retention during failover
??? Troubleshooting HA Setup:
?? Verify HA heartbeat status:

phstatus --show
?? Check if MongoDB and PostgreSQL replication is working correctly
?? Ensure the VIP is properly assigned and accessible in the network
?? Look for failover event logs in /opt/phoenix/log
?? Step 2: Synchronizing Configurations Between DC & DR
For DR readiness, configurations must be replicated between the Data Center (DC) and Disaster Recovery (DR) site.
? Key Configuration Synchronization Areas:
?? Policies & Rules: Ensure correlation rules & threat intelligence are in sync
?? Device Integrations: Verify that devices report logs to both DC & DR
?? Reports & Dashboards: Ensure SOC teams have access to unified reports
??? Troubleshooting Sync Issues:
?? Check rsync logs if configuration files aren’t syncing

?? Ensure firewall rules allow bidirectional sync traffic between DC & DR
?? Validate cron jobs or automation scripts responsible for periodic sync
?? Step 3: Testing HA & DR for Full Redundancy
Once the setup is complete, testing is essential to validate failover capabilities.
? Test Scenarios to Validate HA & DR:
?? Simulate Supervisor Node Failure and monitor failover behavior
?? Disable a Worker Node and verify event processing continuity
?? Perform a DR switch-over and confirm log retention & access
?? Run a network failure test to check auto-recovery mechanisms
??? Troubleshooting HA & DR Failover: ?? If failover doesn’t occur, check HA priority settings:
CopyEdit
cat /opt/phoenix/config/phoenix_config.txt | grep HA
?? Monitor network latency between DC & DR, as high latency can delay failover
?? Ensure NTP synchronization between HA nodes for event consistency
? Final Checklist for a Successful HA-DR Setup:
?? HA Supervisor & Worker nodes configured and monitored
?? DC-DR synchronization is working without delays
?? Failover & recovery tests performed successfully
?? Log data retention is ensured even after failover
?? Security event visibility remains consistent
With this robust HA-DR setup in FortiSIEM, organizations can ensure maximum uptime, efficient log management, and zero security monitoring downtime in the event of failures.
