Ensure Correct Permissions on Audit Log Files

高级别 2自动化tdsql

说明

If MySQL audit logging is enabled, the audit log files must have restrictive permissions. Audit logs are critical for security monitoring and forensic analysis. Searches /data/tdsql (the benchmark path; confirm audit_txsql_audit_dir points inside it). Counts audit files accessible by other users; expected 0600 or 0640, owner mysql:mysql.

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 '*audit*' -perm /o+rw -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 '*audit*' -type f -exec chmod 640 {} +; chown mysql:mysql those files.
