 ### Introduction
 
-In this challenge, we will integrate your Azure Arc connected machines with [Azure Security Center (ASC)](https://docs.microsoft.com/en-us/azure/security-center/). After completing the previous challenges, you should now have an Azure subscription with one or more Azure Arc managed servers. You should also have an available Log Analytics workspace and have deployed the Log Analytics agent to your server(s).

 ### Challenge
 
-1. Enable Azure Security Center on your Azure Arc connected machines.
+1. Enable Microsoft Defender for Cloud on your Azure Arc connected machines.
 
 ### Success Criteria
 
-1. Open Azure Security Center and view the [Secure Score](https://docs.microsoft.com/en-us/azure/security-center/secure-score-security-controls) for your Azure arc connected machine.
+1. Open Microsoft Defender for Cloud and view the [Secure Score](https://learn.microsoft.com/en-us/azure/defender-for-cloud/secure-score-security-controls) for your Azure arc connected machine.

  [Azure Arc enabled servers](https://docs.microsoft.com/en-us/azure/azure-arc/servers/overview) allows customers to use Azure management tools on any server running in any public cloud or on-premises environment. In this hack, you will be working on a set of progressive challenges to showcase the core features of Azure Arc. 
  
- In the first few challenges, you will set up your lab environment and deploy servers somewhere other than Azure. Then, you will use Azure Arc to project these servers into Azure, and begin to enable Azure management and security tools on these servers. On successive challenges, you will apply [Azure Policy](https://docs.microsoft.com/en-us/azure/governance/policy/overview) and enable other Azure services like [Azure Security Center](https://docs.microsoft.com/en-us/azure/security-center/) on your projected workloads.
