AIRA-032 — Dalaran

Rule definition

# OWASP: sensitive SSH filesystem write via agent tool (direct, no ingestion step)
rule: AIRA-032
meta:
  name: write ssh path
  severity: critical
  action: block
  description: >
    Block pending writes targeting SSH trust surfaces (.ssh/ directories and
    authorized_keys). Complements AIRA-030 (/etc/ direct writes) and AIRA-031
    (fetch→sensitive persist) for host-integrity and privilege-abuse paths where
    agents may install backdoor keys or poison SSH config without an external
    fetch step in the same run.
