Ensure the Cassandra service is run as a non-root user (Automated)

Profile Applicability

• Level 1 - Cassandra on Linux

Description

Though Cassandra database may be run as root, it should run as another non-root user.

Rationale

One of the best ways to reduce your exposure to attack is to create a unique, unprivileged user and group for the server application. A best practice is to follow is ensuring processes run with a user with least privilege.

Impact

None

Audit Procedure

Logon to the server where Cassandra is running and run the following command:

ps -aef | grep cassandra | grep java | cut -d' ' -f1

This will show who is running the Cassandra binary.

If the user is root or has excessive privileges then this is a finding.

Remediation

Create a group for cassandra (if it does not already exist):

sudo groupadd cassandra

Create a user which is only used for running Cassandra and its related processes.

Replacing <DIRECTORY_WHERE_CASSANDRA_INSTALLED> with the full path of where Cassandra binaries are installed.

Replacing <USERID_NUMBER> with a number not already used on the server.

sudo useradd -m -d <DIRECTORY_WHERE_CASSANDRA_INSTALLED> -s /bin/bash -g cassandra -u <USERID_NUMBER> cassandra

Default Value

No default value - depends on installation.
