A security baseline in Microsoft Intune is a collection of recommended security settings that are designed to provide a baseline level of protection for devices and applications in an organization. Security baselines are used to help organizations meet their security and compliance requirements by providing a standardized set of security settings that can be applied to devices and applications.

Microsoft Intune provides pre-defined security baselines that can be applied to devices running Windows 10 and Microsoft Edge. These baselines include recommended settings for device security, network security, and application security. Organizations can also create custom security baselines that are tailored to their specific needs and requirements.

Here are some examples of security settings that might be included in a security baseline :
* Enabling BitLocker encryption on Windows devices
* Disabling insecure network protocols, such as SMBv1
* Enabling Windows Defender Antivirus and configuring its settings
* Configuring Microsoft Edge to use the highest level of security for browsing
* Enabling password complexity requirements and other security settings for Windows devices

Once a security baseline is created, it can be applied to devices and applications in an organization using Intune policies. Intune provides tools for monitoring compliance with security baselines and for reporting on any issues or exceptions.
