InformationCreate separate userid and group for Cassandra.
All processes need to run as a user with least privilege. This mitigates the potential impact of malware to the system.
SolutionCreate 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 <USERID_NUMBER> with a number not already used on the server
