By: Ravi Devarasetty

Overview of this book

Many organizations are moving away from on-premises solutions to simplify administration and reduce expensive hardware upgrades. This book uses real-world examples of deployments to help you explore Zscaler, an information security platform that offers cloud-based security for both web traffic and private enterprise applications. You'll start by understanding how Zscaler was born in the cloud, how it evolved into a mature product, and how it continues to do so with the addition of sophisticated features that are necessary to stay ahead in today's corporate environment. The book then covers Zscaler Internet Access and Zscaler Private Access architectures in detail, before moving on to show you how to map future security requirements to ZIA features and transition your business applications to ZPA. As you make progress, you'll get to grips with all the essential features needed to architect a customized security solution and support it. Finally, you'll find out how to troubleshoot the newly implemented ZIA and ZPA solutions and make them work efficiently for your enterprise. By the end of this Zscaler book, you'll have developed the skills to design, deploy, implement, and support a customized Zscaler security solution.

Configuring ZPA applications

An application is defined as a combination of a port, along with a Fully Qualified Domain Name (FQDN), IP address, or a local domain hostname.

The next step after deploying the App Connectors is to configure the private applications themselves. After authenticating into the ZPA Admin Portal, the enterprise administrator needs to navigate to Administration -> Application Management -> Application Segments. This page displays a list of the existing application segments.

DNS search domains

If the enterprise wants end users to be able to access the private applications using a short name rather than the FQDN, the administrator needs to add the relevant domains that can be used to form an FQDN. For this, the administrator needs to select the DNS Search Domains icon from the top right-hand corner of the Application Segments page.

In the pop - up window, enter the domain name and then click on the Add More link to add more domains on a new line...
