cyberstrikeus 1.1 Ensure a separate user and group exist for Cassandra
Profile Applicability
- Level 1 - Cassandra on Linux
- Level 2 - Cassandra on Linux
Description
Create separate userid and group for Cassandra.
Rationale
All processes need to run as a user with least privilege. This mitigates the potential impact of malware to the system.
Audit
Logon to the server where Cassandra is installed. To confirm existence of the group, execute the following command:
$ getent group | grep cassandra
To confirm existence of the user, execute the following command:
$ getent passwd | grep cassandra
If either the group or user do not exist, or if the user is not a member of the group, 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.
sudo useradd -m -d /home/cassandra -s /bin/bash -g cassandra -u <USERID_NUMBER> cassandra
Replacing with a number not already used on the server
Default Value
No default user or group exists for Cassandra in a fresh installation.
