Ensure SSL Key Files Have Appropriate Permissions

TinggiLevel 1Otomatismariadb

Deskripsi

When configured to use SSL/TLS, MariaDB relies on Secure Sockets Layer (SSL) key files, which are stored on the host's filesystem. These SSL key files are subject to the host's permissions and ownership structure. Every file named by an ssl_ca/ssl_cert/ssl_key/ssl_crl variable must be -r-------- mysql:mysql (directories in ssl_capath/ssl_crlpath are skipped). 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).

Cara pemeriksaan

Metode audit: Perintah shell

shell

[ "$(id -u)" -eq 0 ] || exit 1; d=$(mariadb -NBe "SELECT @@global.datadir" 2>/dev/null) || exit 1; l=$(mariadb -NBe "SELECT VARIABLE_VALUE FROM information_schema.GLOBAL_VARIABLES WHERE LOWER(VARIABLE_NAME) REGEXP '^.*ssl_(ca|capath|cert|crl|crlpath|key)\$' AND VARIABLE_VALUE <> ''" 2>/dev/null) || exit 1; n=0; for f in $l; do case "$f" in /*) ;; *) f="$d/${f#./}" ;; esac; [ -f "$f" ] || continue; [ "$(stat -c '%a %U %G' "$f")" = "400 mysql mysql" ] || n=$((n+1)); done; [ "$n" -eq 0 ] && echo compliant || echo "$n noncompliant files"

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

chown mysql:mysql <ssl_file> && chmod 400 <ssl_file> for every ssl_ca/ssl_cert/ssl_key/ssl_crl file in use.
