AWS Threat Monitoring

  • Updated

Active threats within an organization's AWS environments typically arise from these two main sources:

  1. System and application vulnerabilities on EC2 instances.
  2. Malicious network activities, API activities and resource operations.

AWS provides two native services -- AWS Inspector and AWS GuardDuty -- to address the above, respectively.

Inspector performs automated scans of active EC2 instances to identify exposure and vulnerabilities.

GuardDuty continuously analyzes network events (VPC Flow Logs and DNS logs) and API events (CloudTrail logs) to identify malicious/unauthorized activity and behavior.

JupiterOne integrates with both AWS Inspector and GuardDuty out-of-the-box to provide a consolidated UI to manage, visualize and correlate the findings from these services.

Accessing the Findings in the Alerts app

You can see all open findings in the Alerts app.


Expanding a finding will give you a visual graph showing the resources the selected finding is related to. You can interact with the graph and drill down to see additional relationships and context to perform further analysis.


Note that JupiterOne also integrates with several other security scanners, including Tenable, Veracode, and WhiteHat. All security findings are aggregated in the above centralized dashboard for easy management, filtering and reporting. You can also import manual pen test findings. See this doc for more details.

Correlation and Alerting

Using J1QL, you can easily perform correlation of Inspector and GuardDuty findings and the resources they impact. For example, the following query identifies suspicious activities against any EC2 instance that also has high severity vulnerability findings.

Find aws_guardduty_finding that relates to aws_instance
  that has aws_inspector_finding with numericSeverity > 7 return tree

Here is an example graph returned by the above query:


You can correlate Inspector and GuardDuty findings with other security scanner findings as well, if you have those integrations configured.

You can also set up alerts and receive notification on certain findings. For example, the following query can be used to set up an alert rule for high risk findings that impact production resources:

Find (Host|DataStore|Application|CodeRepo|Account|Service|Network)
  with tag.Production=true
  that has Finding with severity='High' or numericSeverity>7

See this alert rule in the JupiterOne common-alerts rule pack on Github.
