Which method is used to securely connect privileged remote access applications in Zscaler?

The method used to securely connect privileged remote access applications in Zscaler is encapsulated tunnel forwarding. This approach establishes a secure, encrypted tunnel between a user’s endpoint and the Zscaler platform. The encapsulation adds a layer of protection, ensuring that the data transmitted across the network is securely encrypted, which is essential for safeguarding sensitive information related to privileged remote access.

Encapsulated tunnel forwarding allows for secure communication by encapsulating the original packets into a new packet format that secures the transmitted data. This is particularly important in scenarios where remote access involves sensitive data or requiring compliance with regulatory standards. The encrypted tunnel protects against eavesdropping and man-in-the-middle attacks, providing a secure method for handling privileged access.

Using direct IP connections would expose the remote session to potential threats without the necessary security measures in place. Protocols like FTP are inherently insecure as they do not encrypt the data being transferred, making them unsuitable for privileged access. Similarly, unsecured web access lacks the encryption needed to protect sensitive information during transmission. Thus, encapsulated tunnel forwarding is the optimal method for ensuring secure and authenticated access in the context of Zscaler's remote access solutions.
