Ensure Backup Data Is Encrypted

高等級 2人工審核tdsql

說明

Backup data should be encrypted at rest for all backup types: physical backup (XtraBackup), logical backup (mydumper), and ZooKeeper data backup.

檢查方式

稽核方法: 人工審核

此項建議無法自動檢查。當您傳入 --include-manual 時，掃描結果會列出此項目並附帶這些說明。

Confirm backups are encrypted: the xtrabackup/mydumper command lines carry --aesencrypt (ps -ef | grep -E "xtrabackup|mydumper" | grep -- --aesencrypt) and OSS backup metadata shows aesencrypt=1; local backup volumes use LUKS (lsblk -f | grep -i crypt); COS/S3 targets enforce server-side encryption. Unencrypted backups are a finding.

修補方式

修補方法: 操作指南或基礎設施修補檔

TDSQL provides AES + cluster-key based backup encryption at the backup layer (-- aesencrypt and --cluster_identify command-line arguments). To enable it: 1. Modify the cluster backup policy in the OSS management platform to enable backup encryption:  <backup increment_flag="1" increment_interval_day="1" mydumper="0" xtrabackup="1" aesencrypt="1" /> 2.
