Ensure security-relevant runtime GFlags are configured correctly

MoyenneNiveau 1Revue manuelleyugabytedb

Description

YugabyteDB exposes runtime parameters across five context levels: backend, postmaster, sighup, superuser, and user. Unauthorized or misconfigured settings at these levels can enable denial of service, information disclosure, audit evasion, or privilege escalation.

Méthode de vérification

Méthode d'audit: Revue manuelle

Cette recommandation ne peut pas être vérifiée automatiquement. Une analyse la liste avec ces instructions lorsque vous passez --include-manual.

Run SELECT name, setting, context FROM pg_settings WHERE name IN ('ignore_system_indexes','jit_debugging_support','jit_profiling_support','log_connections','log_disconnections','allow_system_table_mods','logging_collector','shared_preload_libraries','password_encryption','ssl','log_hostname','log_line_prefix','log_statement','log_error_verbosity','session_preload_libraries','local_preload_libraries') ORDER BY name; and compare each value with the benchmark reference table.

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Set all required parameters in a single --ysql_pg_conf_csv GFlag on every YB-TServer. The flag may be specified only once per process; if it is repeated, only the last occurrence takes effect. Entries whose values contain commas (such as log_line_prefix) must be enclosed in double quotes per the flag's CSV format.
