 By default, Microsoft enforces Hypertext Transfer Protocol Secure (HTTPS) for all traffic that's transmitted to customers' web browsers, including sign-in and all traffic thereafter. The use of TLS v1.2 enables a secure tunnel for traffic to flow through. ACLs on access and core routers ensure that the source of the traffic is consistent with what is expected.
 
-An important distinction in this architecture, when it's compared to traditional security architecture, is that there are no dedicated hardware firewalls, specialized intrusion detection or prevention devices, or other security appliances that are normally expected before connections are made to the Azure production environment. Customers usually expect these hardware firewall devices in the Azure network; however, none are employed within Azure. Almost exclusively, those security features are built into the software that runs the Azure environment to provide robust, multi-layered security mechanisms, including firewall capabilities. Additionally, the scope of the boundary and associated sprawl of critical security devices is easier to manage and inventory, as shown in the preceding illustration, because it is managed by the software that's running Azure.

 ## Core security and firewall features
 Azure implements robust software security and firewall features at various levels to enforce security features that are usually expected in a traditional environment to protect the core Security Authorization boundary.
