Group Policy is a Windows feature that provides a wide range of advanced settings for network administrators. They use Group Policy to regulate the working environment of users and computer accounts within Active Directory. This provides a centralized platform for administrators to configure and manage user settings, operating systems, and applications.
When using Group Policies effectively, you have the ability to increase the security of a user’s computer. This helps to safeguard against internal and external threats.
Below, we will explore everything about Group Policies and explain GPOs. We will explain how system administrators can help to prevent data breaches by using them.
What is a Group Policy Object (GPO)?
Essentially, a Group Policy Object (GPO) refers to a cluster of settings that are developed using the Microsoft Management Console (MMC) Group Policy Editor.
GPOs may link to a single or multiple Active Directory containers that contain sites, domains, and/or organizational units (OUs). The MMC gives users the ability to create GPOs. These outline registry-based policies, security options, and software installation among other things.
Active Directory employs the application of GPOs in a coordinated sequence ie. local policies, site policies, domain policies, and OU policies.
How Does it Work and Why is it Important?
Group Policy ensures that your information and your central IT infrastructure is configured in a secure manner. For those that make use of Windows directly from the box, it doesn’t provide comprehensive protection against threats.
GPOs are very effective in addressing these gaps in security when just using Windows without any additional configurations. Neglecting to address these security gaps is a risky proposition for any organization. This is because it leaves your data and IT infrastructure exposed to threats.
GPOs are particularly helpful when implementing a policy of least privilege. This is where users only have the permissions necessary to fulfil their duties. Typically, this is done by disabling Local Administrator rights globally within a network. Then, you can grant admin privileges to individuals, teams or departments - depending on their role.
The features of Group Policies are invaluable. They assist organizations by drastically improving security. Some of the methods involved include disabling outdated protocols and preventing unauthorized users from making changes.
Benefits of Using Group Policy
Besides the stringent security protocols offered by Group Policy, there are many other advantages that organizations will find beneficial.
Password Policy
Organizations often operate with generic password policies that might be too relaxed. An example of this is where users often have standard passwords that don’t have an expiry date.
Organizations can find serious breaches of their systems when:
- passwords are too simple
- common passwords are used
- if passwords aren’t changed on a regular basis
GPOs can help to regulate the length and complexity of passwords to enhance security.
Systems Management
Organizations usually employ GPOs to assist with simplifying tasks that are time-consuming.
Organizations may increase their productivity and optimize their performance levels by using GPOs to apply a standardized configuration to new users and devices that enter their domain.
Health Checking
Organizations often use GPOs to install software updates and system patches. This is vital in ensuring that the system environment is healthy and updated against all types of security threats.
Group Policy Limitations
It is important for organizations to also be aware of the limitations that come with using GPO.
GPO editor is not very user friendly and can be tricky to use. Administrators will require knowledge of PowerShell in order to conduct updates for GPO.
GPO updates are randomly processed almost every two hours or whenever a user reboots a computer. Although, administrators can specify the update range from 0 minutes up to 45 days. If administrators do specify 0 minutes, the GPOs have a default setting that attempts to run an update every 7 seconds. This can prove to be inconvenient and is likely to obstruct your network with unnecessary traffic.
GPOs can also come under cyberattacks. Hackers can change local GPOs on a computer in an attempt to travel laterally across the network. This type of breach can be incredibly difficult to detect if Group Policy auditing and monitoring is not activated.
Managing Group Policy
The Group Policy Management Console (GPMC) helps administrators manage Group Policy. The purpose of GPMC is to assist administrators by providing a comprehensive platform for all Group Policy management functions.
GPMC serves particularly well in aligning the user interface of Group Policy with the intricate operations of the organization.
The Bottom Line
Group Policy is extremely useful in protecting an organization’s systems and data. It saves time, is cost-effective, increases productivity, provides enhanced security, and enables a centralized location for all configurations.
Organizations should not hesitate to implement Group Policy in their systems, and administrators should embrace the Group Policy Object. This will help to optimize and protect the organization’s information and central IT infrastructure.
