10. Final Checklist After ISO Installation

• [ ] Web UI reachable (HTTPS)
• [ ] NTP synchronized (systemctl status ntpd)
• [ ] At least one log source sending events
• [ ] Offense generated (trigger a test rule)
• [ ] Backup of /opt/qradar/conf and PostgreSQL DB

Phase 3: The Installer Walkthrough

1. Language: Choose English.
2. Installation Destination: Select both disks you created.
   • Manual Partitioning (Let the installer do auto, but verify):
   • Disk 1 (sda): /boot, /, swap
   • Disk 2 (sdb): /store
3. Software Selection: Leave as "QRadar Server" (default).
4. Network & Hostname:
   • Enable eth0 and eth1.
   • Set a static IP address (e.g., 192.168.1.100). Do not use DHCP for a production SIEM.
5. Begin Installation: This takes 20 to 45 minutes depending on your disk speed.

1. Overview: What You’re Installing

• Product: IBM QRadar Community Edition (CE)
• License: Free, perpetual (50 EPS limit)
• Purpose: SIEM for log management, threat detection, compliance (PCI DSS, HIPAA)
• Typical Use: Lab, learning, small home/SOHO environment

5. Common Troubleshooting Tips

• "Connection Refused" in Browser:
  • Check if the firewall is blocking the connection.
  • Ensure the VM has an IP address. Run ip addr in the VM terminal. If it shows 127.0.0.1 only, your network adapter is not bridged correctly.
• Installation Fails (Storage Error):
  • QRadar requires significant space for /store partitions. Ensure your virtual disk is thick-provisioned, not thin-provisioned, and is at least 300 GB.
• System is Slow:
  • The Java-based web interface is heavy. If the UI freezes, increase the VM RAM to 12 GB or 16 GB.
• Log Sources Not Working:
  • Community Edition has limited capabilities. Ensure you are trying to add standard syslog sources.
