What is an Application Segment?

An Application Segment refers specifically to a list of Fully Qualified Domain Names (FQDNs) or IP Addresses that group together applications, allowing for more effective policy management and traffic steering. By identifying applications through their specific FQDNs or IP addresses, organizations can apply security policies, access controls, and enable proper monitoring of application traffic.

This concept is pivotal within Zscaler's framework as it enables organizations to ensure that security and access policies are applied based on the application context rather than simply on IP addresses or ports. This method enhances the granularity and precision of the security measures while managing user access based on the applications used.

Other options, while related to networking and application management, do not accurately represent what an Application Segment is. For example, appending DNS suffixes or listing ports are specific technical configurations that do not capture the broader strategic grouping of applications by their FQDNs or IP addresses, which is the fundamental aspect of application segmentation in the context of Zscaler.
