To enable application detection on plain-text traffic that has been decrypted by FortiADC, the administrator must perform two configuration tasks on CL-1:

Enable SSL offloading in the firewall policy and select the SSL-Offload protocol options profile.

Enable application control in the firewall policy and select the SSL-Offload-App-Detect application list. References: https://docs.fortinet.com/document/fortigate/6.4.0/cookbook/103438/application-detection-on-ssl-offloaded-traffic

The MTA adapter feature on FortiSandbox is a feature that allows FortiSandbox to act as a mail transfer agent (MTA) that can receive, inspect, and forward email messages from external sources. The MTA adapter feature can be used to integrate FortiSandbox with third-party email security solutions that do not support direct integration with FortiSandbox, such as Microsoft Exchange Server or Cisco Email Security Appliance (ESA). The MTA adapter feature can also be used to enhance email security by adding an additional layer of inspection and filtering before delivering email messages to the final destination. The MTA adapter feature can be enabled on FortiSandbox in an HA-Cluster, which is a configuration that allows two FortiSandbox units to synchronize their settings and data and provide high availability and load balancing for sandboxing services. However, one statement about this solution that is true is that the MTA adapter is only available in the primary node. This means that only one FortiSandbox unit in the HA-Cluster can act as an MTA and receive email messages from external sources, while the other unit acts as a backup node that can take over the MTA role if the primary node fails or loses connectivity. This also means that only one IP address or FQDN can be used to configure the external sources to send email messages to the FortiSandbox MTA, which is the IP address or FQDN of the primary node.

The customer wants to deploy a solution to authenticate the clients connected to a hardware switch interface of a FortiGate 400E device. A hardware switch interface is an interface that combines multiple physical interfaces into one logical interface, allowing them to act as a singleswitch with one IP address and one set of security policies. The customer wants to use 802.1X authentication for this solution, which is a standard protocol for port-based network access control (PNAC) that authenticates clients based on their credentials before granting them access to network resources. One condition that allows authentication to the client devices before assigning an IP address is that devices connected directly to ports 3 and 4 can perform 802.1X authentication. This is because ports 3 and 4 are part of the hardware switch interface named “lan”, which has an IP address of 10.10.10.254/24 and an inbound SSL inspection profile named “ssl-inspection”. The inbound SSL inspection profile enables the FortiGate device to intercept and inspect SSL/TLS traffic from clients before forwarding it to servers, which allows it to apply security policies and features such as antivirus, web filtering, application control, etc. However, before performing SSL inspection, the FortiGate device needs to authenticate the clients using 802.1X authentication, which requires the clients to send their credentials (such as username and password) to the FortiGate device over a secure EAP (Extensible Authentication Protocol) channel. The FortiGate device then verifies the credentials with an authentication server (such as RADIUS or LDAP) and grants or denies access to the clients based on the authentication result. Therefore, devices connected directly to ports 3 and 4 can perform 802.1X authentication before assigning an IP address. Another condition that allows authentication to the client devices before assigning an IP address is that client devices must have 802.1X authentication enabled. This is because 802.1X authentication is a mutual process that requires both the client devices and the FortiGate device to support and enable it. The client devices must have 802.1X authentication enabled in their network settings, which allows them to initiate the authentication process when they connect to the hardware switch interface of the FortiGate device. The client devices must also have an 802.1X supplicant software installed, which is a program that runs on the client devices and handles the communication with the FortiGate device using EAP messages. The client devices must also have a trusted certificate installed, which is used to verify the identity of the FortiGate device and establish a secure EAP channel. Therefore, client devices must have 802.1X authentication enabled before assigning an IP address.

The output of the status of high availability on the FortiGate shows that the cluster mode is active-passive, which means that only one FortiGate unit is active at a time, while the other unit is in standby mode. The active unit handles all traffic and also sends HA heartbeat packets to monitor the standby unit. The standby unit becomes active if it stops receiving heartbeat packets from the active unit, or if it receives a higher priority from another cluster unit. In active-passive mode, all cluster units share a virtual MAC address for each interface, which is used as the source MAC address for all packets forwarded by the cluster.
