Ensure per-account connection limits are used

NiskaNivo 1Automatskapostgres

Opis

Limiting concurrent connections to a PostgreSQL server can be used to reduce the risk of Denial of Service (DoS) attacks. Counts login roles with an unlimited (-1) connection limit. 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.

Kako se proverava

Metod provere: SQL upit

sql_query

out=$(psql -X -U "${PGUSER:-postgres}" -d "${PGDATABASE:-postgres}" -tAc "SELECT count(*) FROM pg_roles WHERE rolname !~ '^pg_' AND rolcanlogin AND rolconnlimit = -1" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Očekivani izlaz: 0

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

ALTER ROLE <dbuser> CONNECTION LIMIT <reasonable concurrent connection count>; for every login role reported (SELECT rolname FROM pg_roles WHERE rolcanlogin AND rolconnlimit = -1).
