Microsoft IIS CIS Benchmark Assessment v1.2.1

Microsoft IIS CIS Benchmark Assessment tool

The Microsoft IIS CIS Benchmark is a set of security best practices and configuration guidelines designed to help administrators secure Internet Information Services (IIS), Microsoft's web server platform. The Microsoft IIS CIS Benchmark Assessment tool can be used to perform CIS Benchmark assessment for multiple IIS Servers. The Center for Internet Security (CIS) publishes these benchmarks to provide actionable recommendations for securing IIS environments, reducing vulnerabilities, and ensuring compliance with industry standards.

Key Areas that SmartProfiler checks as paprt of the assessment are:

1. IIS Server Configuration: The benchmark covers fundamental security settings for IIS, including disabling unnecessary modules, enforcing strong authentication, and ensuring that security features such as SSL/TLS are properly configured.

2. Access Control: Guidelines include securing access to IIS servers by enforcing least privilege principles, ensuring proper user permissions, and restricting administrative access to trusted personnel.

3. Logging and Monitoring: The benchmark emphasizes the importance of enabling and configuring IIS logging for auditing and troubleshooting. It also recommends integrating IIS with centralized logging and monitoring solutions to detect suspicious activity.

4. Patching and Updates: The CIS Benchmark encourages the regular application of security patches and updates to IIS and its underlying components to mitigate known vulnerabilities.

5. Security Headers and Features: Recommendations include enforcing secure HTTP headers, such as Strict-Transport-Security, and disabling insecure features like Directory Browsing and HTTP TRACE to reduce attack surfaces.

6. Encryption and Data Protection: The benchmark advises enabling strong SSL/TLS encryption and securing sensitive data through mechanisms such as file encryption and password policies.

By following these guidelines, administrators can harden their IIS servers and reduce the risk of exploitation from cyber threats.

The Center for Internet Security is a nonprofit entity whose mission is to ‘identify, develop, validate, promote, and sustain best practice solutions for cyberdefense.’ It draws on the expertise of cybersecurity and IT professionals from government, business, and academia from around the world. To develop standards and best practices, including CIS benchmarks, controls, and hardened images, they follow a consensus decision-making model. SmartProfiler is designed to support CIS Standards designed for Microsoft 365 and Azure Assessments.
