-Network Security Perimeter allows organizations to define a logical network isolation boundary for PaaS resources (for example, Azure Storage account and SQL Database server) that are deployed outside your organization’s virtual networks. It restricts public network access to PaaS resources within the perimeter; access can be exempted by using explicit access rules for public inbound and outbound.

-## How does Network Security Perimeter work?
+## How does a network security perimeter work?
 
 When a network security perimeter is created and the PaaS resources are associated with the perimeter in enforced mode, all public traffic is denied by default thus preventing data exfiltration outside the perimeter.  
 
 Access rules can be used to approve public inbound and outbound traffic outside the perimeter. Public inbound access can be approved using Network and Identity attributes of the client such as source IP addresses, subscriptions. Public outbound access can be approved using FQDNs (Fully Qualified Domain Names) of the external destinations. 
 
-For example, upon creating a network security perimeter and associating a set of PaaS resources like Azure Key Vault and SQL DB in enforced mode, with the perimeter, all incoming and outgoing public traffic is denied to these PaaS resources by default. To allow any access outside the perimeter, necessary access rules can be created. Within the same perimeter, profiles may also be created to group PaaS resources with similar set of inbound and outbound access requirements.
