Limitations of Group Policy EditorThe gpedit application is very simplistic for a tool that is supposed to help secure your entire enterprise. GPO updates occur at some time interval on computers throughout the network differently or on a reboot. Therefore, the time between your changes and all computers on the network receiving this change is unknown. Attackers can change local group policies using the same gpedit, or PowerShell, which can undo any protections you have enabled on that system. Several companies provide alternative group policy editing tools, and you can learn how to make all the changes with PowerShell to make your job simpler. However, gpedit does not have any native auditing built-in, so you need to have a rock-solid change management plan and audit all GPO changes independently to ensure your enterprise remains secure. It’s crucial to monitor Active Directory for any changes made to Group Policy – often, these changes are the first signals in APT attacks, where hackers intend to be in your network for a while, and they want to remain hidden. Varonis detects threats by monitoring and correlating current activity against normalized behavior and advanced data security threat models to detect APT attacks, malware infections, brute-force attacks, including attempts to change GPOs. Check out this PowerShell course by Adam Bertram, where he teaches you how to use PowerShell to manage Active Directory. Once you learn the basics, you can start managing GPOs with PowerShell, and it’s worth 3 CPE credits!
