### Active Directory Security Checks (by Sean Metcalf - @Pyrotek3)

#### General Recommendations

* Manage local Administrator passwords (LAPS).

* Implement RDP Restricted Admin mode (as needed).

* Remove unsupported OSs from the network.

* Monitor scheduled tasks on sensitive systems (DCs, etc.).

* Ensure that OOB management passwords (DSRM) are changed regularly & securely stored.

* Use SMB v2/v3+

* Default domain Administrator & KRBTGT password should be changed every year & when an AD admin leaves.

* Remove trusts that are no longer necessary & enable SID filtering as appropriate.

* All domain authentications should be set (when possible) to: "Send NTLMv2 response onlyrefuse LM & NTLM."

* Block internet access for DCs, servers, & all administration systems.

#### Protect Admin Credentials

* No "user" or computer accounts in admin groups.

* Ensure all admin accounts are "sensitive & cannot be delegated".

* Add admin accounts to "Protected Users" group (requires Windows Server 2012 R2 Domain Controllers, 2012R2 DFL for domain protection).

* Disable all inactive admin accounts and remove from privileged groups.

#### Protect AD Admin Credentials

* Limit AD admin membership (DA, EA, Schema Admins, etc.) & only use custom delegation groups.

* ‘Tiered’ Administration mitigating credential theft impact.

* Ensure admins only logon to approved admin workstations & servers.

* Leverage time-based, temporary group membership for all admin accounts

#### Protect Service Account Credentials

* Limit to systems of the same security level.

* Leverage “(Group) Managed Service Accounts” (or PW >20 characters) to mitigate credential theft (kerberoast).

* Implement FGPP (DFL =>2008) to increase PW requirements for SAs and administrators.

* Logon restrictions – prevent interactive logon & limit logon capability to specific computers.

* Disable inactive SAs & remove from privileged groups.

#### Protect Resources

* Segment network to protect admin & critical systems.

* Deploy IDS to monitor the internal corporate network.

* Network device & OOB management on separate network.

#### Protect Domain Controllers

* Only run software & services to support AD.

* Minimal groups (& users) with DC admin/logon rights.

* Ensure patches are applied before running DCPromo (especially MS14-068 and other critical patches).

* Validate scheduled tasks & scripts.

#### Protect Workstations (& Servers)

* Patch quickly, especially privilege escalation vulnerabilities.

* Deploy security back-port patch (KB2871997).

* Set Wdigest reg key to 0 (KB2871997/Windows 8.1/2012R2+): HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSecurityProvidersWdigest

* Deploy workstation whitelisting (Microsoft AppLocker) to block code exec in user folders – home dir & profile path.

* Deploy workstation app sandboxing technology (EMET) to mitigate application memory exploits (0-days).

#### Logging

* Enable enhanced auditing

* “Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings”

* Enable PowerShell module logging (“*”) & forward logs to central log server (WEF or other method).

* Enable CMD Process logging & enhancement (KB3004375) and forward logs to central log server.

* SIEM or equivalent to centralize as much log data as possible.

* User Behavioural Analysis system for enhanced knowledge of user activity (such as Microsoft ATA).

#### Security Pro’s Checks

* Identify who has AD admin rights (domain/forest).

* Identify who can logon to Domain Controllers (& admin rights to virtual environment hosting virtual DCs).

* Scan Active Directory Domains, OUs, AdminSDHolder, & GPOs for inappropriate custom permissions.

* Ensure AD admins (aka Domain Admins) protect their credentials by not logging into untrusted systems (workstations).

* Limit service account rights that are currently DA (or equivalent).
