Which of the following is an authentication method used for Identity Awareness?

SSL is a transport encryption protocol and is not itself an authentication method used by the Identity Awareness blade to identify users.

Captive Portal is a built-in Identity Awareness authentication method that redirects unauthenticated users to a web login page hosted by the Security Gateway. When users authenticate through the portal, the gateway maps their IP address to their identity, enabling identity-based policy enforcement. It is explicitly listed in Check Point documentation as one of the supported Identity Awareness acquisition methods.

PKI (Public Key Infrastructure) is a certificate management framework used for SIC and VPN authentication, not a user identity acquisition method for Identity Awareness.

RSA refers to an encryption algorithm and token-based MFA product, but it is not a standalone Identity Awareness authentication method in Check Point.
