GPO GUIDs are different than AD object GUIDs since some GPO GUIDs need to be the same across AD instances.The Default Domain Policy should only contain the following settings:The Default Domain Policy default settings for Windows Server 2012 R2 are shown in the above graphic.The Default Domain Controllers Policy should only contain the following settings:The Default Domain Controllers Policy default settings for Windows Server 2012 R2 are shown in the above graphics.Creating Domain & Domain Controller Security Baseline GPOsIt is very tempting to put customized settings into the default GPOs. The Active Directory Best Practices Analyzer looks for the default GPOs to ensure theyвЂ™re applied correctly. This is to ensure that Windows can quickly find these GPOs and if theyвЂ™re deleted, they need to be restored/ recreated. Default Domain Policy вЂ“ GUID: Note that these GPO GUIDs are the same for every Active Directory domain instance. Domain Controller Events to Monitor (Event Logs)As with any major change to infrastructure, please test before deploying changes.Default Domain & Domain Controller Group Policies (GPOs)When an Active Directory domain is first created, there are two GPOs created by default:

Set this to be 1 or higher so users canвЂ™t simply keep cycling their new password until they roll through the password history to get back to their favorite password. Maximum Password Age: 60 вЂ“ 180 depending on organizational requirements and minimum password length. Enforce Password History: 24 (the default is fine) If there are accounts that require less restrictive requirements, use Fine-Grained Password Policy to provide more lax password settings for exceptions. I recommend tightening these up to make them more secure. Just donвЂ™t add new settings to this GPO keep it clean.The default password policy settings in the Default Domain Policy GPO leave a lot to be desired.

Baseline Domain Controller Security PolicyThe Baseline Domain Security Policy should contain settings that apply to the entire domain.The best way to create a secure Domain Policy and a secure Domain Controller Policy is to download the Microsoft Security Compliance Manager (currently at version 4.0) and select вЂњSecurity ComplianceвЂќ option under the operating system version for which you want to create the security baseline GPOs. Set to configure how long until the account is automatically unlock without requiring help desk assistance.The first step is to create two new GPOs (these are examples, call them whatever you like): Reset account lockout counter after: 5 вЂ“ 60 minutes Set to configure how many invalid logon attempts are required before locking the account. Account lockout threshold: 5 вЂ“ 20 invalid logon attempts Set to some value to mitigate password guessing attempts

Some government systems require it, but please test extensively with applications first.As part of developing your Security Baseline, there are several large organizations that have spent time and money determining whatвЂ™s вЂњsecureвЂќ: FIPS compatible encryption can actually cause problems. If you are unsure if you need it, donвЂ™t enable it. This will improve your DC security baseline if you have minimal security settings already configured, especially if you have no existing workstation GPO.Most of the settings included are identified and described in the вЂњProtecting Domain ControllersвЂќ & вЂњRecommended Group Policy SettingsвЂќ sections further down in this post.Microsoft SCM Domain Security Compliance Policy(review settings and test before deploying)Microsoft SCM Domain Controller Security Compliance PolicyIf one of the templates includes FIPS compliant encryption, validate whether or not you need it set since Microsoft doesnвЂ™t recommend this as of 2014. Then apply this GPO to your Domain Controllers. Create a new empty GPO in the domain and вЂњImport SettingsвЂќ from the SCM GPO backup so the new GPO has the same settings as the SCM export.

In addition to these, configure additional GPOs with a few new settings for testing. Use separate GPOs for major configuration settings: Windows Workstation Configuration, Windows Server Configuration, User Configuration, etc. I tend to fall in the middle.

Any security patch labelled вЂњcriticalвЂќ and applies to DCs needs to be installed as soon as possible. Apply critical security patches first. One popular approach is to apply the patch(es) to even numbered DCs at first, and then deploy to odd numbered DCs. Apply patches to a subset of Domain Controllers first to let them вЂњbakeвЂќ for a period of time, then apply to another set, and then install the patch on all of them. Mitigating concerns around breaking operations and ensuring security patches are applied promptly is a delicate balance, certainly more art than science. The concern centers around вЂњwhat if I apply a patch and it breaks something?вЂќ which is a valid one.
