Ensure a separate user and group exist for Cassandra

MediumLevel 1Automatedcassandra

Description

Create separate userid and group for Cassandra. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Passes when the cassandra group and user exist and the user is a member (primary or supplementary) of the group.

How it is checked

Audit method: Shell command

shell

g=$(getent group cassandra) || exit 1; u=$(getent passwd cassandra) || exit 1; gid=$(printf '%s' "$g" | cut -d: -f3); ugid=$(printf '%s' "$u" | cut -d: -f4); members=$(printf '%s' "$g" | cut -d: -f4); if [ "$gid" = "$ugid" ] || printf '%s' ",$members," | grep -q ',cassandra,'; then echo compliant; else echo 'user not in group'; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

groupadd cassandra; useradd -m -d /home/cassandra -s /bin/bash -g cassandra -u <UID> cassandra (use an unused UID).
