Securing Windows 10: Creating a Baseline Using CIS Benchmark and STIG
Securing the Windows 10 operating system is paramount to safeguarding sensitive data and protecting against emerging cyber threats. To establish a robust security baseline, it is essential to leverage industry-recognized standards and best practices. In this blog post, we will explore the latest CIS Benchmark and STIG (Security Technical Implementation Guide) as authoritative references for creating a comprehensive security baseline for Windows 10. By implementing the recommendations outlined in these benchmarks, organizations can enhance their Windows 10 security posture effectively.
- Understand the CIS Benchmark and STIG
The CIS Benchmark and STIG are guidelines developed by the Center for Internet Security and the Defense Information Systems Agency, respectively. These benchmarks provide detailed configuration recommendations for securing Windows 10 systems based on industry expertise and practical experience.

- User Account Control (UAC) Configuration
Configure User Account Control (UAC) to the highest level (Always notify) to ensure that administrative actions require user consent. This helps prevent unauthorized changes to system settings and enhances the overall security posture of Windows 10.
- Windows Updates and Patch Management
Regularly apply Windows updates to ensure the operating system is equipped with the latest security patches and fixes. Establish a robust patch management process to automate and streamline the deployment of updates.
- Account Security Measures
Enforce strong password policies, including complexity requirements, minimum password length, and regular password expiration. Implement multi-factor authentication (MFA) for user accounts, particularly for privileged accounts, to provide an additional layer of security.
- Audit Logging and Monitoring
Enable auditing of security events to monitor potential security incidents effectively. Configure an appropriate audit policy to log relevant events, such as failed logon attempts, privilege escalation, and changes to critical system files. Implement a robust monitoring system or leverage a Security Information and Event Management (SIEM) solution to detect and respond to security events in real-time.
- Network Security Controls
Enable and configure Windows Firewall to control incoming and outgoing network traffic. Implement appropriate rules and restrictions to allow only necessary network communication. Disable unnecessary network services and protocols to reduce the attack surface and limit potential vulnerabilities.
- Secure Configuration Settings
Harden Windows 10 by implementing recommended security configurations. Disable unnecessary features, secure network protocols, and configure access controls to minimize the risk of exploitation.
- Application Whitelisting and Execution Policies
Implement application whitelisting to allow only authorized and trusted applications to run on Windows 10 systems. Define and enforce execution policies to prevent the execution of malicious scripts and unauthorized code.
- Device and Data Encryption
Enable full disk encryption using BitLocker or similar encryption solutions to protect sensitive data stored on Windows 10 devices. Additionally, encrypt removable media to ensure data confidentiality and integrity.
- Incident Response Planning
Develop a comprehensive incident response plan that outlines the steps to be taken in the event of a security incident. This plan should include incident identification, containment, eradication, recovery, and lessons learned.
Conclusion
Creating a security baseline for Windows 10 based on the latest CIS Benchmark and STIG is a proactive step towards strengthening the security posture of your organization. By following these guidelines and implementing the recommended security measures, you can significantly reduce the risk of security breaches, protect sensitive data, and stay one step ahead of emerging threats in the dynamic cybersecurity landscape.
Remember to regularly review and update your security baseline to align with new releases and emerging best practices to ensure ongoing protection.
