![]() This is often the reason so many people have Domain Admin rights. ![]() There is no easy process to delegate rights to all systems like DNS, DHCP, group policy, and so on. With that said Microsoft does not make it easy to get away from Domain admin rights. Again temporary is OK but it needs to be removed as soon as the work is done. This is not a Microsoft best practice and I would advise against it. You may read other articles and forums to put your secondary account in the Domain Admins group. Basically, this means all users should log on with an account that has the minimum permissions to complete their work. Instead, follow the least privileged administrative model. Instead create two accounts, a regular account with no admin rights and a privileged account that is used only for administrative tasks.ĭo not put your secondary account in the Domain Admins group, at least permanently. You should not be logging in every day with an account that is a local admin or has privileged access (Domain Admin). Use Two Accounts or more (Regular and Administrator Account) It’s very common to have way too many accounts in the DA group. I know first hand as I’ve recently gone through this process. The process to remove accounts from the DA group is not easy. This can defiantly slow down an attacker. These hashes can be obtained from end user computers.Īll it takes is for one compromised computer or a user account for an attacker to compromise a network.Ĭleaning up the Domain Admins group is a great first step to increasing your network security. Pass the hash allows an attacker to use the password hash to authenticate to remote systems instead of the regular password. One method of doing this is called pass the hash. Once attackers gain access to one system they can move laterally within a network to seek out higher permissions (domain admins). It’s become way too easy for attackers to obtain or crack user credentials. This process is also recommended for the Enterprise Admins, Backup Admins, and Schema Admin groups. When the work is done you should remove the account from the DA group. Microsoft recommends that when DA access is needed, you temporarily place the account in the DA group. It is recommended to have no day to day user accounts in the Domain Admins group, the only exception is the default Domain Administrator account.ĭomain Admins are what the bad guys try to seek out. They can have access to the entire domain, all systems, all data, computers, laptops, and so on. Members of Domain Admins and other privileged groups are very powerful. Limit the use of Domain Admins and other Privileged Groups Now let’s dive into the list of Active Directory Security Best Practices. If they can get access to your computer or your login then they could potentially gain Full access to Active Directory and own your network. In addition to vulnerabilities, it becomes very easy for hackers to just steal or obtain user credentials which then gives them access to your data. When accessing a document on the network, OneDrive, printing to the network printer, accessing the internet, checking your email, and so on, all of these resources often go through Active Directory to grant you access.Īctive Directory has been around for a long time and over the years malicious actors have discovered vulnerabilities in the system and ways to exploit them. Even in the cloud or hybrid environments, it can still be the centralized system that grants access to resources. In many organizations, Active Directory is the centralized system that authenticates and authorizes access to the network. ![]() Why Securing Active Directory is Essential Document delegation to Active Directory.Use latest ADFS and azure security features.Monitor DNS logs for malicious network activity.Monitor DHCP logs for connected devices.Use two factor for office 365 and remote access.Use secure DNS services to block malicious domains.Patch management and vulnerability scanning. ![]() Do not install additional software or server roles on DCs.Remove Users from the Local Administrator Group.Find and remove unused user and computer accounts.Password complexity sucks (use passphrases).Enable audit policy settings with group policy.Disable the local administrator account (on all computers).Secure the domain administrator account.Limit the use of Domain Admins and other Privileged Groups.You don’t have to spend a fortune to improve security there are many no cost and low cost solutions that I’ll show you in this guide.ĪD Security topics covered in this guide: In this guide, I’ll share my recommendations for Active Directory Security and how you can improve the security of your Windows domain environment. This is the most comprehensive list of Active Directory Security Best Practices online. ![]()
