zammad-addon-hardening

A Zammad addon that hardens a Zammad instance according to CDR's needs.

The hardening applied consists of:

  • Prevent sensitive information from being leaked in notification emails
  • Zammad external services for geoip, maps, image, and calendar are disabled
  • Disable client side stats
  • Set minimum password length to 10
  • Prevent customers from creating tickets in the web ui
  • Disable user registration
  • Remove default "nicole.braun@zammad.org" account

  1. Edit the files in src/

    Migration files should go in src/db/addon/hardening (see this post)

  2. Update version and changelog in hardening-skeleton.szpm

  3. Build a new package make

    This outputs dist/hardening-vXXX.szpm

Create a new migration

Included is a helper script to create new migrations. You must have the python inflection library installed.
