Limit Accepted Transport Layer Security (TLS) Versions

高级别 2自动化mysql

说明

MySQL supports multiple protocols of TLS. The higher the version the stronger the security and/or better the performance. Also review performance_schema.status_by_thread (Ssl_version) for clients still negotiating old versions. 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).

检查方式

审计方法: SQL 查询

sql_query

out=$(mysql -NBe "SELECT IF(FIND_IN_SET('TLSv1', @@global.tls_version) = 0 AND FIND_IN_SET('TLSv1.1', @@global.tls_version) = 0, 'compliant', 'noncompliant')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

Set tls_version=TLSv1.3 (or TLSv1.2,TLSv1.3) under [mysqld] in /etc/my.cnf (or /etc/mysql/mysql.conf.d/mysqld.cnf) (or SET PERSIST tls_version then ALTER INSTANCE RELOAD TLS), then restart MySQL.
