Ensure pg_hba.conf does not use 'trust' or 'password' authentication

嚴重等級 1自動化postgres

說明

trust allows login without any credential and password sends the password in clear text. The CIS PostgreSQL 18 Benchmark covers pg_hba.conf only through the manual checks 5.3/5.4; this rule automates that part by reading pg_hba_file_rules (superuser). Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.

檢查方式

稽核方法: SQL 查詢

sql_query

out=$(psql -X -U "${PGUSER:-postgres}" -d "${PGDATABASE:-postgres}" -tAc "SELECT count(*) FROM pg_hba_file_rules WHERE auth_method IN ('trust','password')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

預期輸出: 0

修補方式

修補方法: 操作指南或基礎設施修補檔

Replace trust/password entries in pg_hba.conf with scram-sha-256 (or peer for local administrative sockets), then SELECT pg_reload_conf();
