Ensure the YugabyteDB service is run as a non-root user

How it is checked

Audit method: Shell command

out=$(ps -eo user=,comm= 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk '$2 == "yb-master" || $2 == "yb-tserver" {n++; if ($1 == "root") r++} END {if (n == 0) print "not running"; else if (r > 0) print "root"; else print "compliant"}'

Expected output

compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Create a dedicated yugabyte user and group, chown the installation and fs_data_dirs to it and start yb-master/yb-tserver as that user (User=yugabyte in the service unit).
