Hello Sysnimda,

DMZ strategy needs to be really looked at from the security perspective and the requirements.

There are multiple options available which are commonly used.


 1. No Domain - Easiest solution. If the number of machines are less in DMZ - its an overhead to keep a dedicated domain or domain controller in DMZ Segment. 
 2. Dedicated Isolated Forest - If more machines needs to be managed in DMZ segment, Its good to have an isolated domain only for DMZ segment which doesn't talk with internal network.
 3. Extending production domain to DMZ - I dont recommend this as its more vulnerable. If this needs to be considered, Look for the possibility for placing RODCs in this segment.


Good luck
Shaba

Great info Shaba! What about a SQL server I currently have internally which is tied to IIS/webserver and will be put in DMZ? Should I move entire DB into DMZ? One more thing...should I have a WAF in front of DMZ? Thank you!

What’s the best and secure way to setup a web server within a DMZ? A couple of simple external sites and sql server. Should I put a DC RODC inside DMZ or just open up ports to sync AD? or should I not have it connected to AD?

DMZ and syncing AD

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Microsoft Azure is a cloud computing platform and infrastructure for building, deploying and managing applications and services through datacenters. It provides both platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems. Cloud Services is a PaaS environment and can be used to create scalable applications and services; there are specific software development kits (SDKs) provided by Microsoft for Python, Java, Node.js and .NET. Azure also has file and storage services, data management, analytics and DNS services.

Windows Server 2016 is the successor to Windows Server 2012 R2. Built upon the same core code as Windows 10, Windows Server 2016 brings enhancements in security, servicing, and connectivity. A particular focus on this release was hybrid-cloud scenarios, and has close ties to Azure and other Microsoft cloud initiatives. This does not detract from the many improvements that are available for on-premises-only deployments

Windows Server 2016 comes in Datacenter, Standard, and Essentials editions, and for servicing, has adopted windows 10's cumulative model. The new nano-server install is designed to be remotely managed and is designed to be kept current through continuous feature updates. The full GUI install operates similarly to windows 10's "Long Term Servicing Branch" (LTSB) model with cumulative security updates.

Windows Server 2016 has also shifted from a per-processor-and-CAL licensing model to a per-core-and CAL licensing model. This brings Windows Server's licensing more in line with Microsoft's other products and makes hybrid-cloud license planning easier as well.
