Ensure Correct Permissions on Backup Directories

高级别 1自动化tdsql

说明

TDSQL backup directories must have restrictive permissions. Backup files contain complete copies of the database. Key paths: Local backup: /tdsqlbackup/ (default) ZooKeeper backup: /data/home/zkback/ Checks /tdsqlbackup and /data/home/zkback (at least one must exist). Counts files that grant the listed permission to other users; any match fails, and a missing directory fails. (o+r). Expected: directories 0750.

检查方式

审计方法: Shell 命令

shell

n=0; for p in "/tdsqlbackup" "/data/home/zkback"; do [ -e "$p" ] && n=$((n+1)); done; [ $n -gt 0 ] || exit 1; c=0; for p in "/tdsqlbackup" "/data/home/zkback"; do [ -e "$p" ] || continue; c=$((c + $(find "$p" ! -type l -perm /o+r -print 2>/dev/null | wc -l))); done; echo $c

预期输出: 0
