Ensure Correct Permissions on TDSQL Data Directories

高等級 1自動化tdsql

說明

TDSQL data directories and MySQL instance data directories should have restrictive permissions. Only the TDSQL service account should have read/write access. TDSQL creates data directories with 0755 by default, but stricter permissions are recommended. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Uses TDSQL_DATA (default /data/tdsql/data) for the instance data directory. Counts files that grant the listed permission to other users; any match fails, and a missing directory fails. (o+rw; sockets and symlinks excluded). Expected: directories 0750, files 0640, owner tdsql/mysql.

檢查方式

稽核方法: Shell 指令

shell

n=0; for p in "${TDSQL_DATA:-/data/tdsql/data}"; do [ -e "$p" ] && n=$((n+1)); done; [ $n -gt 0 ] || exit 1; c=0; for p in "${TDSQL_DATA:-/data/tdsql/data}"; do [ -e "$p" ] || continue; c=$((c + $(find "$p" ! -type l ! -type s -perm /o+rw -print 2>/dev/null | wc -l))); done; echo $c
