Security Options

Applies to

  • Windows 11
  • Windows 10

Provides an introduction to the Security Options settings for local security policies and links to more information.

The Security Options contain the following groupings of security policy settings that allow you to configure the behavior of the local computer. Some of these policies can be included in a Group Policy Object and distributed over your organization.

When you edit policy settings locally on a device, you only affect the settings on only that device. If you configure the settings in a Group Policy Object (GPO), the settings apply to all devices that are subject to that GPO.

For info about setting security policies, see Configure security policy settings.
