Update to the Azure Secured Workstation

The update to the Secured Workstations Reference Architecture was released this week, and reflects the addition of several Key updates include - Here's the new content in summary:
    • Setting up WAF blocking all outbound connections
      • This is an interesting section that was provided by a colleague who helped define a set of white-listed URL's and by design block all other traffic. I'd note this is a benchmark of URL's you can use and block when managing Azure.  
    • Improved conditional access
      • Conditional access is also important to ensure that workstation is the only way you manage your Azure subscription. The addition addresses the limitation of managing your cloud from ONLY a secure workstation, and prevent legacy protocols that may not be as secure.
    • Setting up ATP, sentinel for monitoring
      • Detecting and monitoring your network with the newly minted Azure SIEM. Sentinel offers a great way to agriggate your detection platform. This also provides a good means to collect your alerts.
    • Addition of Applocker monitoring using MMA
      • Monitoring applocker provides your best way to know what application is running, or installed on a secured workstation. The sample monitoring and script provides a way to quickly enable and track all application deployments.
The changes are designed to help continue drive the advancement of the secured workstation solution, and drive improved protection.

Additionally I've made two small correction that are now reflected in the architecture - 
  • Addition of hardware selections for root of trust in a supply chain
  • Change Low security to Basic security
Let me know if you find the information useful.

Protecting sensitive data

Image
Last month I wrote an article on key things to consider when protecting high valued assets or sensitive data. The article called Security Tip of the Month: Protecting Highly Sensitive Information addressed some of the key items that organizations should consider when protecting data that has the possible impact on an organization that is irreparable. As my article stated the cost of protecting this data tends to be higher than most data. Fact is that this data is not traditionally just sensitive such as credit card data, or HR data. Key indicators of what is High Value Data can be summed up like this. Assets that are considered to be of high value will frequently have the potential to cause the following conditions if they are lost or divulged: •        Loss of life - such as an informant list •        Regulatory fines - such as financial performance data •        Significant damage to the business - such as code signing and encryption keys (private) or trade secrets

Secure workstation - Root of trust to manage the cloud

Image
Two months ago I introduced the Azure secure workstation, and I’ve had the privilege to present the ideal to some great audiences. From the discussions, a common question I’ve been asked is a pattern that would provide the Secured PAW model lock down scenario to exclusively manage an Azure Portal (EG how to I assure only secured workstation, and users assigned to the program can manage my cloud services)? In this article I’ll provide the NEXT step to accomplish exactly that outcome. This includes additional configurations that I only lightly covered, or net new technology to apply since the publishing of the doc. Proposed outcome “ How do I” Use a Secured workstation (that I can trust) to manage my Azure cloud. Here’s how I would deploy the solution. First I will start by deploying the Secured Workstation model this using the secured profile. New technology, and capabilities to add: Hardware root of trust – in our solution we post the idea that you can

Why is privileged access important?

Image
Last year about this time I had published updates to the Azure Secure Workstation that was originally released two years ago. And This month the solution has been considerably rewritten and revised to provide a better more complete management for privileged access!  Collaborating with two great security experts James Noyce, and Mark Simos The content got a massive overhaul, and a broad perspective on what it takes to build and manage a comprehensive privileged access solution, including account management, device management, intermediaries such as VPN's and interfaces such as Web and Cloud services. Additionally, the solution was uniformly designed with three distinct security levels that anyone reading the article can deploy from a more flexible Enterprise security, to a comprehensive isolated PAW or privileged Access Management. Over the past two years I've been working to explain and illustrate how you can use a cloud-based solution to build an effective Zero tr
