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-v110-3.7/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/cis-cassandra40-v110-3-7, but wait for my approval before writing files or running scripts.

3.7 Review User-Defined Roles
Profile Applicability
- Level 1 - Cassandra
- Level 1 - Cassandra on Linux
Description
The MEMBER_OF column found in the system_auth.roles table shows roles granted to roles.
Rationale
The MEMBER_OF column shows whoever has roles granted to roles and depending on the role and the privileges grant to the role should be limited. Limiting the accounts that have the certain roles reduces the chances that an attacker can exploit these capabilities.
Audit
Execute the following SQL statement to audit this setting:
select role, can_login, member_of from system_auth.roles;
Looking for can_login which tells you that role can log into cassandra and member_of is when roles are granted to roles.
Remediation
Looking at those users from the query that have member_of that is NOT null, decide if that user truly needs that role, if not, for each user, issue the following SQL statement (replace <is_member> with the value of member_of returned by the query in the audit procedure):
revoke <is_member> from role;
Default Value
By default, no user-defined roles exist.
References
None specified in benchmark.
CIS Controls
v8:
- 6.8 Define and Maintain Role-Based Access Control - Define and maintain role-based access control, through determining and documenting the access rights necessary for each role within the enterprise to successfully carry out its assigned duties. Perform access control reviews of enterprise assets to validate that all privileges are authorized, on a recurring schedule at a minimum annually, or more frequently.
v7:
- 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.
