CIS Control 4.1: Establish and Maintain a Secure Configuration Process
Secure configuration is the foundation of a hardened security posture. CIS Control 4.1 requires you to systematically establish, document, and maintain secure configurations across all enterprise assets—from endpoints to servers to applications. Without it, misconfigurations become attack vectors that attackers exploit before you even know they exist.
What this means
This control requires organizations to create and enforce a repeatable process for configuring enterprise assets securely. This includes end-user devices (laptops, desktops, portable devices, mobile phones), non-computing IoT devices, servers, operating systems, and applications. The process must be documented, reviewed annually, and updated whenever significant changes occur in your enterprise infrastructure or threat landscape. The goal is to eliminate unnecessary services, apply security settings consistently, and reduce your attack surface.
How to comply
- 1.Document your secure configuration baseline for each asset type (endpoints, servers, applications) with hardening standards
- 2.Define and enforce configuration standards that disable unnecessary services, ports, and features by default
- 3.Implement automated configuration management tools to deploy and maintain configurations consistently across your environment
- 4.Establish a change management process that governs all configuration updates and security patches
- 5.Conduct annual reviews of your configuration documentation and update baselines based on new threats or organizational changes
- 6.Test configuration changes in a non-production environment before enterprise-wide deployment
- 7.Monitor and audit actual configurations against approved baselines to detect and remediate drift
- 8.Document exceptions to approved configurations with written justification and compensating controls
Evidence auditors look for
- Configuration management policy and procedures document
- Documented secure configuration baselines for each asset class
- Configuration hardening guides for operating systems and applications
- Automated configuration scanning reports showing compliance with baselines
- Change log showing configuration updates and annual reviews
- Evidence of testing configuration changes before deployment
- Configuration drift audit reports with remediation records
- Exception log with business justification and compensating control documentation
