Should external DNS be in DMZ?
If you have only one set of DNS servers for both internal and external DNS, you should place them in the DMZ and have internal users access them from the internal network rather than place them in the internal network and configure in your firewall for external DNS requests.
Should a firewall be in the DMZ?
Typically, an additional firewall will be responsible for protecting the DMZ from exposure to everything on the external network. All services accessible to users on communicating from an external network can and should be placed in the DMZ, if one is used.
Should Adfs be in DMZ?
For deployment in on-premises environments, we recommend a standard deployment topology consisting of one or more AD FS servers on the internal corporate network, with one or more Web Application Proxy (WAP) servers in a DMZ or extranet network.
Is DMZ same as DNS?
While a router requires DNS configuration to work properly, many routers will work fine with the DMZ disabled. In addition, DNS primarily affects data traffic inside your network and outbound to the Internet; the DMZ typically relates to inbound traffic from other machines outside your local network. …
Why do companies put an external DNS server in their DMZ?
The DMZ firewall adds a security line of defense to the internal network to be protected, which is generally considered to be very secure. The main benefit of a DMZ is to provide an internal network with an additional security layer by restricting access to sensitive data and servers.
How DMZ can improve network security?
The main benefit of a DMZ is to provide an internal network with an advanced security layer by restricting access to sensitive data and servers. A DMZ enables website visitors to obtain certain services while providing a buffer between them and the organization’s private network.
Does DMZ increase speed?
A true DMZ is basically a section of your network that is exposed to the internet but do not connect to the rest of your internal network. It should be noted that DMZ or DMZ Host does not improve the performance speed or latency of your router’s connection to the server.
Is ADFS still needed?
Only a limited number of cases require ADFS If we analyze the decision flow, we can conclude that only a limited number of cases require to have ADFS. Only when there is an unsupported authentication method or complex claim rules that cannot be migrated to Azure AD.
Why do you need a rodc in DMZ?
Based on the above statement from the “RODC Technical Reference Topics”, communication (in this case DNS) is required from DMZ clients to an internal RWDC in order for dynamic DNS updates to work. I believe this is also the case in your scenario in order to be able to access \\\\domain.local (SMB communication).
What are the benefits of using a rodc?
The main benefits of an RODC are as below: 1 Reduced security risk to a writable copy of Active Directory. 2 Better logon times compared to authenticating across a WAN link. 3 Better access to the authentication resource on the network. 4 Better performance of directory-enabled applications.
Why do I need a domain controller ( rodc )?
Inadequate physical security is the most common reason to consider deploying an RODC. An RODC provides a way to deploy a domain controller more securely in locations that require fast and reliable authentication services but cannot ensure physical security for a writable domain controller.
How is a change replicated to a rodc?
The RODC forwards the write request to a writable domain controller and then replicates the change back from the writable domain controller. For most write operations, the change is replicated back to the RODC during the next scheduled replication interval. In some other cases, the RODC attempts to replicate the change immediately.
