Ensure Correct Permissions on MySQL Binary Log Files

高级别 1自动化tdsql

说明

Binary log files (binlog.*, mysql-bin.*) contain records of all data modifications and must have restrictive permissions. Searches /data/tdsql (the benchmark path). Counts binlog.*, mysql-bin.* and relay-log.* files readable by other users; expected 0640.

检查方式

审计方法: Shell 命令

shell

n=0; for p in "/data/tdsql"; do [ -e "$p" ] && n=$((n+1)); done; [ $n -gt 0 ] || exit 1; c=0; for p in "/data/tdsql"; do [ -e "$p" ] || continue; c=$((c + $(find "$p" -type f \( -name 'binlog.*' -o -name 'mysql-bin.*' -o -name 'relay-log.*' \) -perm /o+r -print 2>/dev/null | wc -l))); done; echo $c

预期输出: 0

修复方式

修复方法: 操作指南或基础设施补丁

find /data/tdsql \( -name 'binlog.*' -o -name 'mysql-bin.*' -o -name 'relay-log.*' \) -exec chmod 640 {} +
