This issue keeps track of all deprecated Falco features that will be removed in Falco 1.0.0:

  • append in Falco rule is deprecated in favor of override (see https://github.com/falcosecurity/falco/pull/2992)
  • syntax like
    yaml
    - rule: Write below etc
      enabled: false
    is deprecated in favor of override (see https://github.com/falcosecurity/falco/pull/2992).
    yaml
      - rule: Write below etc
        enabled: false
        override:
           enabled: replace
    Please note that the enabled key is only deprecated when used as an override! So a rule like this is perfectly legit:
    yaml
    - rule: legit_rule
      desc: legit rule description
      condition: evt.type=open
      output: user=%user.name command=%proc.cmdline file=%fd.name
      priority: INFO
      enabled: false
