Security Onion Console (SOC)¶
Once you’ve run so-allow and allowed your IP address, you can then connect to Security Onion Console (SOC) with your web browser. We recommend chromium or chromium-based browsers such as Google Chrome. Other browsers may work, but chromium-based browsers provide the best compatibility.
Depending on the options you chose in the installer, connect to the IP address or hostname of your Security Onion installation. Then login using the email address and password that you specified in the installer.
Once logged in, you’ll see links on the left side for analyst tools like Alerts, Hunt, PCAP, Kibana, CyberChef, Playbook, TheHive, and ATT&CK Navigator. While Alerts:, Hunt, and PCAP are native to SOC itself, the remaining tools are external and will spawn separate browser tabs.
SOC gives you access to a variety of tools and they all complement each other very well. For example, here’s one potential workflow:
- Check Grafana to make sure your system is healthy.
- Go to the Alerts page and review unacknowledged alerts.
- Once you’ve found an alert that you want to investigate, you might want to expand your search and look for additional logs relating to the source and destination IP addresses, so pivot to Hunt for more information. If any of those additional logs look interesting, you might then want to pivot to PCAP to look at the full packet capture for that stream.
- Send alert to TheHive and document any indicators of compromise (IOCs) found in the previous step.
- Go to Fleet and perform a wider search for those IOCs across all osquery endpoints.
- Use CyberChef to further analyze and decode additional host artifacts.
- Develop a play in Playbook that will automatically alert on IOCs moving forward and update your coverage in ATT&CK Navigator.
- Finally, return to TheHive and document the entire investigation and close the case.
