FortiGate Infrastructure 7.2 Study Guide (p.41): "The RPF check is a mechanism that protects FortiGate and your network from IP spoofing attacks by checking for a return path to the source in the routing table." "FortiGate performs an RPF check only on the first packet of a new session. That is, after the first packet passes the RPF check and FortiGate accepts the session, FortiGate doesn’t perform any additional RPF checks on that session."

A. The RPF check is a mechanism that protects FortiGate and the network from IP spoofing attacks.

This is true because the RPF check verifies that the source IP address of an incoming packet matches the reverse route for that address, meaning that the packet came from a legitimate source and not from an attacker who is trying to impersonate another host. This prevents IP spoofing attacks, where an attacker sends packets with a forged source IP address to bypass security policies or launch denial-of-service attacks1

C. The RPF check is run on the first sent packet of any new session.

This is true because the RPF check is performed only once per session, on the first packet sent by either the client or the server, depending on the direction of the session initiation. This reduces the processing overhead and improves performance2

C: "Operating mode is per-VDOM setting. You can combine transparent mode VDOM's with NAT mode VDOMs on the same physical Fortigate.

D: "Inspection-mode selection has moved from VDOM to firewall policy, and the default inspection-mode is flow, so NGFW Mode can be changed from Profile-base (Default) to Policy-base directly in System > Settings from the VDOM" Page 125 of FortiGate_Infrastructure_6.4_Study_Guide QUESTION NO: 23 51 Which statement is correct regarding the inspection of some of the services available by web applications embedded in third-party websites? A. The security actions applied on the web applications will also be explicitly applied on the third-party websites.

B. The application signature database inspects traffic only from the original web application server.

C. FortiGuard maintains only one signature of each web application that is unique.

D. FortiGate can inspect sub-application traffic regardless where it was originated.

Answer: D

FortiGate Security 7.2 Study Guide (p.310): "Then, FortiGate scans packets for matches, in this order, for the application control profile: 1. Application and filter overrides: If you have configured any application overrides or filter overrides, the application control profile considers those first. It looks for a matching override starting at the top of the list, like firewall policies. 2. Categories: Finally, the application control profile applies the action that you’ve configured for applications in your selected categories."

"If you use multiple source or destination interfaces, or the any interface in a firewall policy, you cannot separate policies into sections by interface pairs—some would be triplets or more. So instead, policies are then always displayed in a single list (By Sequence)."

y default, "fortiguard-anycast" is enabled, and this setting only works with "set protocol https". To use udp (ie. "set protocol udp"), "fortiguard-anycast" must be disabled.

The debug flow output shows the result of a diagnose command that captures the traffic flow between the source and destination IP addresses1. The debug flow output reveals the following information about the traffic flow1:

• The protocol is 1, which means that the traffic uses ICMP protocol2. ICMP is a protocol that is used to send error messages and test connectivity between devices2.
• The session state is 0, which means that a new traffic session was created3. A session is a data structure that stores information about a connection between two devices3.
• The policy ID is 1, which means that the traffic matched the firewall policy with ID 14. A firewall policy is a rule that defines how FortiGate processes traffic based on the source, destination, service, and action parameters4.
• The action is 0, which means that the traffic was allowed by the firewall policy. An action is a parameter that specifies what FortiGate does with the traffic that matches a firewall policy.

Therefore, two conclusions that can be made from the debug flow output are:

• The debug flow is for ICMP traffic.
• A new traffic session was created.

For an IPsec VPN between site A and site B, the administrator has configured the local quick mode selector for site A as 192.168.1.0/24 and the remote quick mode selector as 192.168.2.0/24. This means that the VPN will allow traffic to and from the 192.168.1.0/24 subnet at site A to reach the 192.168.2.0/24 subnet at site B.

To complete the configuration, the administrator must configure the local quick mode selector for site B. To do this, the administrator must use the same subnet as the remote quick mode selector for site A, which is 192.168.2.0/24. This will allow traffic to and from the 192.168.2.0/24 subnet at site B to reach the 192.168.1.0/24 subnet at site A.

Therefore, the administrator must configure the local quick mode selector for site B as 192.168.2.0/24.

An aggregate interface is a logical interface that combines two or more physical interfaces into one virtual interface1. An aggregate interface can increase network bandwidth and provide redundancy by distributing traffic across multiple physical interfaces using a load balancing algorithm1. An aggregate interface can also support link aggregation control protocol (LACP) to negotiate the link aggregation settings with the connected device1.

FortiGate Security 7.2 Study Guide (p.279): "To apply the video filter profile, proxy-based firewall polices currently allow you to enable the video filter profile. You must enable full SSL inspection on the firewall policy."

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.

You can deploy FSSO w/o installing an agent. FG polls the DCs directly, instead of receiving logon info indirectly from a collector agent.

Because FG collects all of the data itself, agentless polling mode requires greater system resources, and it doesn't scale as easily.

Agentless polling mode operates in a similar way to WinSecLog, but with only two event IDs: 4768 and 4769. Because there's no collector agent, FG uses the SMB protocol to read the event viewer logs from the DCs.

FG acts as a collector. It 's responsible for polling on top of its normal FSSO tasks but does not have all the extra features, such as workstation checks, that are available with the external collector agent.

Strict Reverse Path Forwarding (RPF) is a security feature that is used to detect and prevent IP spoofing attacks on a network. It works by checking the routing information for incoming packets to ensure that they are coming from the source address that is indicated in the packet's header. In strict RPF mode, the firewall will check the best route back to the source of the incoming packet using the incoming interface. If the packet's source address does not match the route back to the source, the packet is dropped. This helps to prevent attackers from spoofing their IP address and attempting to access the network.

FortiGate Infrastructure 7.2 Study Guide (p.264): "...then FortiGate might drop interesting traffic because of the absence of active SAs. To prevent this, you can enable Auto-negotiate. When you do this, FortiGate not only negotiates new SAs before the current SAs expire, but it also starts using the new SAs right away." "Another benefit of enabling Auto-negotiate is that the tunnel comes up and stays up automatically, even when there is no interesting traffic. When you enable Autokey Keep Alive and keep Auto-negotiate disabled, the tunnel does not come up automatically unless there is interesting traffic. However, after the tunnel is up, it stays that way because FortiGate periodically sends keep alive packets over the tunnel. Note that when you enable Auto-negotiate, Autokey Keep Alive is implicitly enabled."

1. Override is disable by default - OK

2. "If the HA uptime of a device is AT LEAST FIVE MINUTES (300 seconds) MORE than the HA Uptime of the other FortiGate devices, it becomes the

primary" The QUESTION NO: here is : HA Uptime of FGVM01000006492 > 5 minutes? NO - 198 seconds < 300 seconds (5 minutes) Page 314 Infra Study Guide.

FortiGate Security 7.2 Study Guide (p.436): "When you configure FortiGate devices in multi-vdom mode and add them to the Security Fabric, each VDOM with its assigned ports is displayed when one or more devices are detected. Only the ports with discovered and connected devices appear in the Security Fabric view and, because of this, you must enable Device Detection on ports you want to have displayed in the Security Fabric. VDOMs without ports with connected devices are not displayed. All VDOMs configured must be part of a single Security Fabric."

"In IKEv1, there are two possible modes in which the IKE SA negotiation can take place: main, and aggressive mode. Settings on both ends must agree; otherwise, phase 1 negotiation fails and both IPsec peers are not able to establish a secure channel."

FortiGate Infrastructure 7.2 Study Guide (p.73): "What about traffic originating from FortiGate? Some system daemons, such as NTP and FortiGuard updates, generate traffic coming from FortiGate. Traffic coming from FortiGate to those global services originates from the management VDOM. One, and only one, of the VDOMs on a FortiGate device is assigned the role of the management VDOM. It is important to note that the management VDOM designation is solely for traffic originated by FortiGate, such as FortiGuard updates, and has no effect on traffic passing through FortiGate."

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."

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."

The host 10.200.3.1 sends a TCP SYN packet on port 10443 to 10.200.1.10, which is the external IP address of the VIP object named VIP in Exhibit B1. The VIP object maps the external IP address and port to the internal IP address and port of the server 10.0.1.10 and 443, respectively1. The VIP object also enables NAT, which means that the source address of the packet will be translated to the IP address of the outgoing interface2.

The firewall policy ID 1 in Exhibit B allows traffic from WAN (port1) to LAN (port3) with the destination address of VIP and the service of HTTPS1. The policy also enables NAT, which means that the source address of the packet will be translated to the IP address of the outgoing interface2.

Therefore, after FortiGate forwards the packet to the destination, the source address, destination address, and destination port of the packet will be 10.200.3.1, 10.0.1.10, and 443, respectively.

You can find more information about VIP objects and firewall policies in the Fortinet Documentation

FortiGate Infrastructure 7.2 Study Guide (p.165): "ZTNA access proxy allows users to securely access resources through an SSL-encrypted access proxy. This simplifies remote access by eliminating the use of VPNs."

This is true because ZTNA access proxy is a feature that allows remote users to access internal applications without requiring VPN or user credentials. ZTNA access proxy uses a secure tunnel between the user’s device and the FortiGate, and authenticates the user based on device identity and context. The user only needs to install a lightweight agent on their device, and the FortiGate will automatically assign them to the appropriate application group based on their device profile. This simplifies remote access and enhances security by reducing the attack surface12

A. In advanced mode, FortiGate can be configured as an LDAP client and group filters can be configured on FortiGate.

This is true because advanced mode allows FortiGate to query the LDAP server directly for user information and group membership, without relying on the collector agent. This enables FortiGate to apply security policies based on LDAP group filters, which can be configured on FortiGate1

D. Advanced mode supports nested or inherited groups.

This is true because advanced mode can handle complex group structures, such as nested groups or inherited groups, where a user belongs to a group that is a member of another group. This allows FortiGate to apply security policies based on the effective group membership of a user, not just the direct group membership1

FortiGate Infrastructure 7.2 Study Guide (p.146): "Also, advanced mode supports nested or inherited groups; that is, users can be members of subgroups that belong to monitored parent groups." "In advanced mode, you can configure FortiGate as an LDAP client and configure the group filters on FortiGate. You can also configure group filters on the collector agent."

To establish an SSL VPN connection between two FortiGate devices, the following two settings are required:

The server FortiGate requires a CA certificate to verify the client FortiGate certificate: The server FortiGate will use a CA (Certificate Authority) certificate to verify the client FortiGate certificate, ensuring that the client device is trusted and allowed to establish an SSL VPN connection.

The client FortiGate requires the SSL VPN tunnel interface type to connect SSL VPN: The client FortiGate must have an SSL VPN tunnel interface type configured in order to establish an SSL VPN connection. This interface type will be used to connect to the server FortiGate over the SSL VPN.
