CloudKnox App for Splunk

Splunk Cloud
This app is NOT supported by Splunk. Please read about what that means for youhere.
Overview
Details
CloudKnox Security created an App for Splunk, which helps enterprises eliminate the #1 risk to cloud infrastructure – accidental misuse and malicious exploitation of high-risk permissions.

On average, human and nonhuman identities use less than 1% of permissions granted. This dangerous, ever-expanding, delta, known as the Cloud Permissions Gap, causes unnecessary stress to IAM and cloud infrastructure teams. The CloudKnox Cloud Permissions Management Platform helps organizations reduce this gap, and improve their MTTR, by quickly identifying permissions, roles and activity across multi-cloud or hybrid cloud infrastructure.

The CloudKnox App for Splunk provides several visualizations to view the "Permission Analytics Report" data collected by CloudKnox Add-on for Splunk.

RECOMMENDED SYSTEM CONFIGURATION

TOPOLOGY AND SETTING UP SPLUNK ENVIRONMENT

  • This app has been distributed in two parts.

    1. CloudKnox Add-on for Splunk, which collects data from CloudKnox using REST API calls.
    2. CloudKnox App for Splunk, which adds dashboards to visualize the CloudKnox data
  • This app can be set up in two ways:

    1. Standalone Mode:
      • Install the CloudKnox App for Splunk and CloudKnox Add-on for Splunk.
      • The CloudKnox App for Splunk uses the data collected by CloudKnox Add-on for Splunk and builds dashboards on it.
    2. Distributed Environment:
      • Install the CloudKnox App for Splunk and CloudKnox Add-on for Splunk on the search head. User does not need to configure an account or create an input in CloudKnox Add-on for Splunk on search head.
      • Install only CloudKnox Add-on for Splunk on the heavy forwarder. User needs to configure account and needs to create data input to collect data from CloudKnox.
      • User needs to manually create an index on the indexer (No need to install CloudKnox App for Splunk or CloudKnox Add-on for Splunk on indexer).

INSTALLATION

CloudKnox App for Splunk can be installed through UI using "Manage Apps" > "Install app from file" or by extracting tarball directly into $SPLUNK_HOME/etc/apps/ folder.

CONFIGURATION

Configure Macros:

Follow the below steps to configure the macros:

  1. Go to "Settings" > "Advanced search" > "Search macros".
  2. Select "CloudKnox App for Splunk" in "App" context dropdown.
  3. Click on cloudknox(2) macro from the shown table.
  4. In the macro definition default value will be index="main" sourcetype="cloudknox:$authSystemtype$:$category$". Update the definition with the index you used for data collection and save the configurations. For example: index="<your_index_name>" sourcetype="cloudknox:$authSystemtype$:$category$".
  5. Search cloudknoxindex macro and repeat the above step. The user is required to configure this macro in order to user the "cloudknox_super_identities_alert".
  6. Next search cloudknox_url_without_scheme macro and replace "xyz.cloudknox.io" with the URL of your CloudKnox instance. The user is required to configure this macro in order to use the drill-down functionality in the "CloudKnox Alerts" dashboard.

Note: If the user has selected a default index (Note: By default, Splunk considers only main index as default index) in "Data Input" configuration during CloudKnox Add-on for Splunk's configuration step, then no need to perform steps 3, 4 and 5.

Configure Savedsearches:

This App contains below 2 schedule searches:
cloudknox_super_identities_snapshot: This savedsearch updates cloudknox_si_snapshot KV store lookup to contain the latest super identities.
cloudknox_super_identities_alert: This alert is generated when any new super identity is added.

Configuring savedsearches is only required if the user wishes to use "cloudknox_super_identities_alert" which triggers an alert when a new super identity is indexed in Splunk. Follow the below steps to configure the savedsearches:

  1. Navigate to Settings > Searches, reports, and alerts
  2. Find "cloudknox_super_identities_snapshot" search
  3. Click on Edit > Edit Schedule
  4. Enable the search and optionally update the "Schedule" and "Time Range" as per the requirement.
  5. Thereafter find the "cloudknox_super_identities_alert" alert
  6. Click on Edit > Edit Alert
  7. Optionally modify the "Time Range" and "Cron Expression" as per the requirement
  8. Add appropriate action to perform when the alert is triggered
  9. Click "Save" to update the settings and enable the alert

TROUBLESHOOTING

  • If you do not see any results in search then check whether you have correctly configured index in the cloudknox(2) macro. Also you can verify if the data is there in the index by running the search query index="<your_index_name>" source="cloudknox".
