Ensure AES Encryption Mode for AES_ENCRYPT/AES_DECRYPT is Configured Correctly

낮음레벨 2자동mysql

설명

A block encryption mode with a Cipher Block Chaining (CBC) mode value and key length of 256 is recommended when using the AES_ENCRYPT() and AES_DECRYPT() functions for encryption. Passes for any aes-256-* mode (ecb, cbc, cfb1, cfb8, cfb128, ofb). 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).

점검 방법

감사 방식: SQL 쿼리

sql_query

out=$(mysql -NBe "SELECT IF(@@global.block_encryption_mode LIKE 'aes-256-%', 'compliant', 'noncompliant')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Set block_encryption_mode=aes-256-cbc under [mysqld] (or SET PERSIST block_encryption_mode = 'aes-256-cbc') after confirming applications that call AES_ENCRYPT/AES_DECRYPT pass the mode they need, then restart.
