Panther-Analysis-Enrichment

Enrichment and Lookup Tables Automation with Gitub Actions

The github action worflows run on configurable schedules.

  1. Runs on a cron schedule
  2. Checks to make sure needed variables/secrets are set before continuing
  3. Checkouts out repo
  4. cURLs the endpoint
  5. Does any cleanup of the json response to get it into a format we can use as a LUT
  6. Downloads PAT
  7. Uploads lookup table using pat upload

Note: Custom schemas need to be configured in Panther before the pat upload will succeed.

Okta Enrichment Action

This action retrieves the user list from Okta's /api/v1/users endpoint.

Set OKTA_DOMAIN and OKTA_API_TOKEN as Github secrets. See Upload to Panther with PAT for required Panther secrets.

Workflow can be found at .github/workflows/okta_users.yml

AWS IP Ranges Action

The AWS IP ranges action retrieves the IP ranges published by AWS from https://ip-ranges.amazonaws.com/ip-ranges.json. Using jq it combines IPv4 and IPv6 records to a ipPrefix key. In a small amount of cases, a range may have multiple records, combining them on ipPrefix with service as an array.

See Upload to Panther with PAT for required Panther secrets.

Example Output:

{"ipPrefix":"99.87.8.0/21","region":"ap-south-2","network_border_group":"ap-south-2","service":["AMAZON"]}

.github/workflows/aws_ip_ranges.yml

See Upload to Panther with PAT for required Panther secrets.

Example Output:

{"ipPrefix":"35.219.128.0/18","service":"Google Cloud","scope":"us-west4"}
