Ensure MariaDB is Bound to One or More Specific IP Addresses

보통레벨 2자동mariadb

설명

By default, the MariaDB server accepts TCP/IP connections from MariaDB user accounts on all server host IPv6 and IPv4 interfaces. You can make this configuration more restrictive by setting the bind_address configuration option to one or more specific IPv4 or IPv6 addresses so that the server only accepts TCP/IP connections on those addresses. Fails when bind_address is empty, '*', '::' or '0.0.0.0' (all interfaces). Runs mariadb -NBe with the client defaults: as root on the server the unix_socket plugin usually authenticates; otherwise put an administrative account in ~/.my.cnf (mode 0600), not MYSQL_PWD (see 1.4/1.6).

점검 방법

감사 방식: SQL 쿼리

sql_query

out=$(mariadb -NBe "SELECT IF(IFNULL(@@global.bind_address, '') NOT IN ('', '*', '::', '0.0.0.0'), 'compliant', 'noncompliant')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Set bind_address=<specific IP> (comma-separated list for several addresses) under [mariadbd] in /etc/mysql/mariadb.conf.d/50-server.cnf (or /etc/my.cnf.d/server.cnf), then restart MariaDB.
