8. Analysis

This chapter explains the possibilities for collecting and analyzing THOR logs.

8.1. ASGARD Analysis Cockpit

The ANALYSIS COCKPIT is the central platform for analyzing THOR logs. It can be used in an environment where scans are controlled by ASGARD Management Center and can also be used where THOR is executed manually or controlled by third party solutions. It is available as a virtual appliance on VMWare and also as a dedicated hardware appliance.

THOR can also be seen or used as hunting solution, it is optimized to avoid false negatives – meaning optimized to not miss an indicator of compromise. On the other side this clearly leads to more anomalies and false positives being reported.

In a scenario where you scan your infrastructure frequently you would either be seeing the same anomalies again and again or you would need to create many rules to filter out these anomalies in order to save analysis time.

The ANALYSIS COCKPIT is designed to facilitate this process and help you generate these rules automatically, so that you can set your baseline-filters after the first scan. After setting the first baseline it is now easy to focus on relevant Alerts and Warnings as only differences between the first and second scans are shown.

The ANALYSIS COCKPIT comes with an integrated and highly configurable ticketing system that helps organizing your analysis workflow. Furthermore, the ANALYSIS COCKPIT comes with a rule based alert forwarding and SIEM integration that makes it easy for your organization to react quickly on new incidents.

8.2. Splunk

We offer a THOR Splunk App and Add-on via the official Splunk App Store. This App helps you to extract the event fields and provides dashboards to get a better overview on distributed runs on multiple systems.

8.3. THOR Util Report Feature

THOR Util provides a feature called "report" that creates HTML reports from text logs of one or more scanned systems.

8.4. Log Analysis Manual

We have written a detailed Log Analysis Manual which:

  • Explains how to analyze THOR logs

  • Contains example logs

  • Lists potential false positives you might encounter

  • And how different attributes are to be evaluated
