Exam NSE7_ZTA-7.2 topic 1 question 15 discussion

Zero Trust Access 7.2 Study Guide Page 117. "You can also configure authentication to the access proxy. ZTNA supports basic HTTP and SAML methods." Zero Trust Access 7.2 Study Guide Page 120. "The authentication scheme defines the method of authentication that is applied. ZTNA supports basic HTTP and SAML methods. Each method has additional settings to define the data source. For example, with basic HTTP authentication, a user database can reference an LDAP server, RADIUS server, local database, or other supported authentication servers that the user is authenticated against."

LDAP (Lightweight Directory Access Protocol) authentication for ZTNA (Zero Trust Network Access) HTTPS access proxy is effectively implemented using a Form-based authentication scheme. This approach allows for a secure, interactive, and user-friendly means of capturing credentials. Form-based authentication presents a web form to the user, enabling them to enter their credentials (username and password), which are then processed for authentication against the LDAP directory. This method is widely used for web-based applications, making it a suitable choice for HTTPS access proxy setups in a ZTNA framework. Reference: FortiGate Security 7.2 Study Guide, LDAP Authentication configuration sections.

You can add authentication to the access proxy, which requires you to configure an authentication scheme and authentication rule on the FortiGate. You use authentication schemes and authentication rules to authenticate proxy-based policies, similar to configuring authentication for explicit and transparent proxy. The authentication scheme defines the method of authentication that is applied. ZTNA supports basic HTTP and SAML methods. Each method has additional settings to define the data source. For example, with basic HTTP authentication, a user database can reference an LDAP server, RADIUS server, local database, or other supported authentication servers that the user is authenticated against.
