Group policies in Microsoft Active Directory Microsoft Active Directory allows you to use group policies to define user or computer settings for an entire group of users or computers at one time. In this blog, we will go through a detailed explanation of what Group Policies and GPOs are, and how system administrators can use them to help prevent data breaches.
Please check your email including spam folder for a link to the whitepaper! GPOs can be associated with a single or numerous Active Directory containers, including sites, domains, or organizational units OUs. The MMC allows users to create GPOs that define registry-based policies, security options, software installation and much more.
Active Directory applies GPOs in the same, logical order; local policies, site policies, domain policies and OU policies. Group Policy Objects can be used in a number of ways that benefit security, many of which will be mentioned throughout this article. Below are a few more specific examples:. The order at which GPOs are processed affects what settings are applied to the computer and user. The local computer policy is the first to be processed, followed by the site level to domain AD policies, then finally into organization units.
The short answer is yes. If you want to ensure that your data and your core IT infrastructure is set up in a secure way, then you probably need to understand how to properly use Group Policy. There are numerous gaps in security, most of which can be addressed using GPOs. A Group Policy object GPO is a collection of Group Policy settings that define what a system will look like and how it will behave for a defined group of users. Every GPO contains two parts, or nodes: a user configuration and a computer configuration.
Likewise, if we dive down into the Administrative Templates of the User node, we see some of the same folders plus some additional ones, such as Shared Folders, Desktop, Start Menu and Taskbar.
The Computer node contains policy settings that are relevant only for computers. These Computer settings could be startup scripts, shutdown scripts, and setting that control how the local firewall should be configured. Every setting is relevant to the computer itself, no matter who is logged on at a given moment.
The User node contains policy settings that are relevant only for users. User settings make sense only on a per-user basis, like logon scripts, logoff scripts and availability of the Control Panel. Think of this as every setting relevant to the currently logged-on user; these settings follow the user to every machine they use. When Group Policy is created at the local level, everyone who uses that machine is affected.
However, once you step up and use Active Directory , you can have nearly limitless Group Policy objects, with the ability to selectively decide which users and computers will get which settings. When we create a GPO, two things happen: We create some brand-new entries within Active Directory, and we automatically create some brand-new files on our domain controllers.
Collectively, these items make up one GPO. Creating a GPO merely makes it available, or ready to be used within the domain where it was created. That association is called linking. Thus, any level in Active Directory can leverage multiple GPOs, which are standing by in the domain ready to be used. Remember, though, unless a GPO is specifically linked to a site, a domain, or an OU, it does not take any effect.
