Run an Arctic Wolf Agent Diagnostic Scan on Linux

You can run an Agent diagnostic scan to get more details about how a vulnerability was detected on a device.

Requirement

• 4 GB of RAM available on your device to generate the expected output.

Before you begin

• Schedule a scan.

  Agent does not have the scanning components pre-installed. When you schedule a scan, the necessary files automatically download.

Steps

1. On the device, create a copy of the /var/arcticwolfnetworks/agent/scans/oval.ini file, and then rename it to oval_copy.ini.

2. In a text editor, open the new oval_copy.ini file.

   Note: You may need admin or superuser permissions to open this file for editing.

3. In the file, find the section starting with [Report: Target results -> JSON events].

   [Report: Target results -> JSON events]
   export.dir: /var/arcticwolfnetworks/agent/scans/reports/vulnerability
   input.type: arf
   output.extension: json
   transform.file: /var/arcticwolfnetworks/agent/scans/scan-utility/tools/arf_xccdf_results_to_json_events.xsl

4. Copy this content and replace the entire section that you located in the previous step.

   [Report: Raw ARF report]
   export.dir: /var/arcticwolfnetworks/agent/scans/reports/vulnerability
   input.type: arf
   output.extension: arf.xml
   
   [Report: Diagnostic HTML report]
   export.dir: /var/arcticwolfnetworks/agent/scans/reports/vulnerability
   input.type: xccdf_results#failureDiag
   output.extension: diagnostic.html
   transform.file: /var/arcticwolfnetworks/agent/scans/scan-utility/tools/xccdf_results_to_html.xsl
   
   [Report: Annotated HTML report]
   export.dir: /var/arcticwolfnetworks/agent/scans/reports/vulnerability
   input.type: json#annotated
   output.extension: annotated.html
   transform.file: /var/arcticwolfnetworks/agent/scans/scan-utility/tools/hostscan_json_to_html.js

   Notes:

   • Always check syntax when editing the .ini file, including confirming that export.dir, input.type, output.extension, and transform.file are each on their own line.
   • To review only results that failed vulnerability scanning checks, ensure that the input.type field in the Report: Diagnostic HTML report section is set to xccdf_results#failureDiag.
   • If you would like to include all successful and failed vulnerability scanning tests, change the input.type field in the Report: Diagnostic HTML report section to xccdf_results#diagnostic. This may be significantly larger in size than using xccdf_results#failureDiag.

5. Open a shell.

6. Click the clipboard to copy this command to the command line to run the scan as the superuser:

   sudo /var/arcticwolfnetworks/agent/scans/jre/jre/bin/java -Xmx4096m -Djoval.shellcommandAdapter.enable=true -Djoval.diagnostics.maxCount=2000 -Dlicense.file=/var/arcticwolfnetworks/agent/scans/scan-utility/rootsecure.com.sig.xml -jar /var/arcticwolfnetworks/agent/scans/scan-utility/Scan-Utilities.jar scan -c /var/arcticwolfnetworks/agent/scans/oval_copy.ini

   Note: For a 64-bit OS, if you receive an insufficient memory error, change the -Xmx4096m flag value in the command to -Xmx6144m to expand the memory size from 4 GB to 6 GB. This means that the device needs 6 GB of space available.

7. Wait for the scan to complete, and then look for the output files in the /var/arcticwolfnetworks/agent/scans/reports/vulnerability/ folder.

   The scan generates these files:

   • Raw XML output (default filename LOCALHOST.arf.xml)
   • HTML Diagnostic Vulnerability long form report (default filename LOCALHOST.diagnostic.html)
   • HTML Annotated report (default filename LOCALHOST.annotated.html)

8. Upload the raw XML output, HTML Diagnostic Vulnerability long form report, and HTML Annotated report to Arctic Wolf, using the link that your Concierge Security® Team (CST) provided. If you do not have a link, contact your CST at security@arcticwolf.com.

9. (Optional) Open the HTML Annotated report in a browser and click Fail in the Rule Results Summary to filter on the vulnerabilities found and view failed tests.

   Note: See Risk Dashboard User Guide to interpret the report results.
