A configuration hardening standard based on the CIS benchmarks can help organizations improve the security of their systems and reduce the risk of cyber attacks. Here is an example of a configuration hardening standard based on the CIS benchmarks:
1. Operating System Hardening
Ensure that the latest patches and security updates are installed on all systems.
Configure the system to use strong passwords and implement password policies to enforce password complexity and expiration.
Disable or remove unnecessary services, protocols, and applications.
Enable auditing and logging, and ensure that logs are reviewed regularly.
Implement firewall rules to restrict incoming and outgoing network traffic.
Configure security settings and permissions to ensure that only authorized users have access to sensitive data and applications.
2. Network Hardening
Configure network devices, such as routers and switches, according to best practices and industry standards.
Implement network segmentation to isolate critical assets and protect them from unauthorized access.
Use secure protocols, such as TLS, for network communication and implement encryption for sensitive data in transit.
Implement intrusion detection and prevention systems to monitor and block suspicious network activity.
3. Application Hardening
Configure web applications according to industry best practices, such as OWASP Top 10 recommendations.
Ensure that applications are updated with the latest security patches and updates.
Implement access controls to restrict access to sensitive data and functionality within the application.
Use encryption to protect sensitive data stored within the application.
4. Database Hardening
Implement secure database configurations and disable unnecessary services and ports.
Use strong passwords and implement password policies to enforce password complexity and expiration.
Use encryption to protect sensitive data stored in the database.
Ensure that only authorized users have access to the database and implement access controls to restrict access to sensitive data.
5. Cloud Hardening
Implement security controls and configurations recommended by the cloud provider.
Implement multi-factor authentication for all users and roles.
Monitor and audit cloud infrastructure for suspicious activity.
Use encryption to protect data in transit and at rest within the cloud environment.
The above configuration hardening standard is based on the CIS benchmarks and can be used as a starting point for organizations looking to improve their system security. Organizations should customize this standard based on their specific needs and requirements, and ensure that the standard is regularly reviewed and updated to stay up-to-date with evolving security threats and industry best practices.
