How does ZPA enhance application access security?

Zscaler Private Access (ZPA) significantly enhances application access security by providing secure, privileged access to applications. It employs a zero-trust security model, which means users are granted access only to the specific applications they need, rather than giving them broad access to the entire network. This minimizes the attack surface and ensures that sensitive applications are only available to authenticated and authorized users.

In this framework, ZPA uses secure tunnels to connect users directly to the applications, regardless of where the user is located. This prevents public exposure, as applications are not directly accessible over the internet. Instead, they remain hidden from unauthorized users, adding an additional layer of security.

The other options do not contribute positively to enhancing application access security. For instance, allowing public internet exposure of all applications would create vulnerabilities by making them accessible to anyone online. Requiring users to log in multiple times could actually lead to user frustration and is not an effective means of enhancing security. Similarly, decentralizing application hosting might have implications for manageability and security, rather than directly addressing access security concerns. Therefore, the response highlighting the provision of secure, privileged access is fundamentally aligned with best practices in cybersecurity.
