## Timeline
- 2026-03-21: Release actual budget
- 2026-03-21: Find the false positive case, and add whitelist
- 2026-05-07: Optimize whitelist expression
## Solution
- Access to fw
- Check the ban list with `sudo cscli alerts list`
- Read the ban case with `sudo cscli alerts inspect $NUMBER`
- Add expressions on whitelist
- evt.Meta.target_fqdn == '{{ services['actualbudget']['domain']['public'] }}.{{ domain['public'] }}' && evt.Meta.http_path contains '/data/migrations/'
- evt.Meta.target_fqdn == '{{ services['actualbudget']['domain']['public'] }}.{{ domain['public'] }}' && evt.Meta.http_status in ['200', '304'] && evt.Meta.http_verb == 'GET' && evt.Meta.http_path contains '/data/migrations/'
- Delete false positive decision
- Check false positive decision with `sudo cscli decision list`
- Delete false positive decision with `sudo cscli decision delete --id $ID`
