Ensure SSL Key Files Have Appropriate Permissions

YüksekDüzey 1Otomatikmysql

Açıklama

When configured to use SSL/TLS, MySQL 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 mysql -NBe with the client defaults: put an administrative account in ~/.my.cnf (mode 0600) or a mysql_config_editor login path, not MYSQL_PWD (see 1.4/1.6).

Nasıl denetlenir

Denetim yöntemi: Kabuk komutu

shell

[ "$(id -u)" -eq 0 ] || exit 1; d=$(mysql -NBe "SELECT @@global.datadir" 2>/dev/null) || exit 1; l=$(mysql -NBe "SELECT VARIABLE_VALUE FROM performance_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"

Beklenen çıktı: compliant

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

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