The Azure AD Application Proxy is a new feature available in Azure WAAD Premium. It allows administrators to securely publish internal websites using Azure’s technology. By using this, it will allow customers to make use of enterprise class hardware in their reverse proxy solutions protecting against DDOS attacks and many more other things. In this post we will look at a simple setup on how this would work.
I’ve been trying to get RDS Gateway to work behind my WAP proxy server which is included in Windows Server 2012 R2 and v.Next version. While it is possible to implement ADFS based authentication based on the URL: http://technet.microsoft.com/en-us/library/dn765486.aspx
But what if we wanted to publish the simple RDS Gateway on our backend server for direct RDP access.. ?
In this post, how to configure a Site2Site VPN connecting using a Checkpoint firewall.
[EDIT: The instructions below are for R77, which is a really old version. I’m currently writing the instructions for the R80.20 version, but it seems it’s a bit harder to get the S2S tunnel up and stable.. certainly on my PPPOE internet connection… more updates soon!
But in case you still want to make this work, please check this hidden article with my notes.. that have not been validated yet! [/EDIT]
While http://msdn.microsoft.com/en-us/library/azure/dn133795.aspx tells you how to create the Site2Site VPN, the firewall part only covers Juniper or Cisco appliances. As I do not own such a device, I got to work on the Checkpoint together with Syed Pasha.
Below the network overview…
Geo Clustering exists in many options, and dependent highly on the requirements and technical capability. This post is to discuss some options and things to consider before deploying any geo-cluster.
Data GEO- Redundancy
The first dependency in clustering is storage capability. Data from the workload in the cluster will be written to disk and that data needs to be available on both sites. Within Microsoft SQL AlwaysOn can replicate the data for the instances and ensure it is available on both sites. It is also possible to have the storage perform data mirroring.
When sending data from site A to site B, two options exist: Synchronous and A-Synchronous.
Synchronous: Data is written to BOTH sites before the application or server receives a successful write notification
A-Synchonous: Data is written to the primary site, the application or server receives the write, and THEN the data is written to the second site.
Within a synchronous architecture, there is very limited chance of data-loss upon a failure, as the application knows the data is written in two locations. With A-synchronous data loss can occur.
While synchronous looks most tempting, it requires fast connections between the storage / servers in order to reduce latency for every I/O write action. Therefore this is not always possible and a-synchronous is the only option left.
Storage mirroring or AlwaysOn data replication must be used to provide data geo-redundancy
So all documentation on BHOLD informs you there are “out of the box” reports available.. none of the articles show which reports they are.. so here they are..
So there are numerous scripts out there for setting the UPN of a user to match the Windows Email Address.. you can even do that in a single command (Powershell).. but would it not be better to actually read the primary e-mail address from the ProxyAddresses? .. so the following script will help you with that: Read more
As we are seeing more and more Windows 2012 based Clouds and services.. I wanted to alert you to the following technology which is becoming more and more available in backend storage systems (and Windows 2012): ODX If you are implementing Hyper-V, File services or any other Windows Server 2012 with a backend SAN […]
Microsoft released a new whitepaper this week that gives an insight in why you should protect your privileged accounts. One of the techniques described is the PassTheHash attack which is a sophisticated attack but fairly easy to execute. These attacks have been seen in the “field” and are being used today. If you work with […]
Did your AD jump back to the year 2000 during the past weekend? .. This could have happened if you are syncing your time with the USNO.NAVY.MIL, as they apparently had a disruption on the 19th. see http://tycho.usno.navy.mil/ntp.html But if time jumped back on your AD, you’re in trouble.. and the way to get […]
So as promised.. the install guide.. or at least some small tips as the installation is not that hard..
First of all, we are going to use a three server architecture. One server for the databases, one for the administration and monitoring and a group policy server.
To start, we need to create some groups in Active Directory, the service account for SQL and a service Account for the MBAM compliancy part. Create the following groups in AD and the following service accounts:
