FortiGate Security 7.2 Study Guide (p.192): 'if using reliable logging, you can encrypt communications using SSL-encrypted OFTP traffic, so when a log message is generated, it is safely transmitted across an unsecure network. You can choose the level of SSL protection used by configuring the enc-algorithm setting on the CLI.'

FortiGate Security 7.2 Study Guide (p.115): 'Enabling ARP reply is usually not required in most networks because the routing tables on the adjacent devices contain the correct next hop information, so the networks are reachable. However, sometimes the routing configuration is not fully correct, and having ARP reply enabled can solve the issue for you. For this reason, it's a best practice to keep ARP reply enabled.'

Flow-based inspection is a type of traffic inspection that is used by some firewall devices, including FortiGate, to analyze network traffic. It is designed to be more efficient and less resource-intensive than proxy-based inspection, and it offers several benefits over this approach.

Two benefits of flow-based inspection compared to proxy-based inspection are:

FortiGate uses fewer resources: Flow-based inspection uses fewer resources than proxy-based inspection, which can help to improve the performance of the firewall device and reduce the impact on overall system performance.

FortiGate adds less latency to traffic: Flow-based inspection adds less latency to traffic than proxy-based inspection, which can be important for real-time applications or other types of traffic that require low latency.

Based on the exhibit, the administrator has configured the FortiGuard Category Based Filter to block access to all social networking sites, and has also configured a Static URL Filter to block access to twitter.com. As a result, users are being redirected to a block page when they try to access twitter.com. To allow users to access twitter.com while blocking all other social networking sites, the administrator can make the following configuration change: On the Static URL Filter configuration, set Action to Exempt: By setting the Action to Exempt, the administrator can override the block on twitter.com that was specified in the FortiGuard Category Based Filter. This will allow users to access twitter.com, while all other social networking sites will still be blocked.

ZTNA (Zero Trust Network Access) is a security architecture that is designed to provide secure access to network resources for users, devices, and applications. It is based on the principle of 'never trust, always verify,' which means that all access to network resources is subject to strict verification and authentication.

Two functions of ZTNA are:

ZTNA provides a security posture check: ZTNA checks the security posture of devices and users that are attempting to access network resources. This can include checks on the device's software and hardware configurations, security settings, and the presence of malware.

ZTNA provides role-based access: ZTNA controls access to network resources based on the role of the user or device. Users and devices are granted access to only those resources that are necessary for their role, and all other access is denied. This helps to prevent unauthorized access and minimize the risk of data breaches.

The SSL VPN idle-timeout setting determines how long an SSL VPN session can be inactive before it is terminated. When an SSL VPN session becomes inactive (for example, if the user closes the VPN client or disconnects from the network), the session timer begins to count down. If the timer reaches the idle-timeout value before the user reconnects or sends any new traffic, the session will be terminated and the associated resources (such as VPN tunnels and virtual interfaces) will be deleted.

Application control is a feature that allows FortiGate to inspect and control the use of specific web applications on the network. When application control is enabled, FortiGate can identify child and parent applications, and can perform different actions on them based on the configuration.

FortiGate Infrastructure 7.2 Study Guide (p.317 & p.320): 'To forward traffic correctly, a FortiGate HA solution uses virtual MAC addresses.' 'The primary forwards the SYN packet to the selected secondary. (...) This is also known as MAC address rewrite. In addition, the primary encapsulates the packet in an Ethernet frame type 0x8891. The encapsulation is done only for the first packet of a load balanced session. The encapsulated packet includes the original packet plus session information that the secondary requires to process the traffic.'
