DevOps & Securitycis-cassandra40-v110-1.1Cis Cassandra40 V110 1.1 is an Agent Skill for devops & security published in the CyberStrikeus/CyberStrike repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Ensure a separate user and group exist for Cassandra
How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Inspect the Agent Skill at https://github.com/CyberStrikeus/CyberStrike/blob/HEAD/.cyberstrike/skill/CIS_benchmarks/Server_Software/Apache_Cassandra/CIS_Apache_Cassandra_4.0_Benchmark_v1.1.0/cis-cassandra40-v110-1.1/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/cis-cassandra40-v110-1-1, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
1.1 Ensure a separate user and group exist for Cassandra
Profile Applicability
- Level 1 - 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 <USERID_NUMBER> with a number not already used on the server.
Default Value
No default - varies by installation method.
References
None specified in benchmark.
CIS Controls
v8:
- 3.3 Configure Data Access Control Lists - Configure data access control lists based on a user's need to know. Apply data access control lists, also known as access permissions, to local and remote file systems, databases, and applications.
v7:
- 5.4 Restrict Administrator Privileges to Dedicated Administrator Accounts - Restrict administrator privileges to dedicated administrator accounts on enterprise assets. Conduct general computing activities, such as internet browsing, email, and productivity suite use, from the user's primary, non-privileged account.
- 4.3 Ensure the Use of Dedicated Administrative Accounts - Ensure that all users with administrative account access use a dedicated or secondary account for elevated activities. This account should only be used for administrative activities and not internet browsing, email, or similar activities.
- 14.6 Protect Information through Access Control Lists - Protect all information stored on systems with file system, network share, claims, application, or database specific access control lists. These controls will enforce the principle that only authorized individuals should have access to the information based on their need to access the information as a part of their responsibilities.
