NEW QUESTION # 23
Which three criteria can a FortiGate device use to look for a matching firewall policy to process traffic?
(Choose three.)
- A. Source defined as internet services in the firewall policy
- B. Highest to lowest priority defined in the firewall policy
- C. Lowest to highest policy ID number
- D. Services defined in the firewall policy.
- E. Destination defined as internet services in the firewall policy
Answer: B,D,E
Explanation:
Explanation
The three criteria that a FortiGate device can use to look for a matching firewall policy to process traffic are:
A: Services defined in the firewall policy - FortiGate devices can match firewall policies based on the services defined in the policy, such as HTTP, FTP, or DNS.
D: Destination defined as internet services in the firewall policy - FortiGate devices can also match firewall policies based on the destination of the traffic, including destination IP address, interface, or internet services.
E: Highest to lowest priority defined in the firewall policy - FortiGate devices can prioritize firewall policies based on the priority defined in the policy. The device will process traffic against the policy with the highest priority first and move down the list until it finds a matching policy.

NEW QUESTION # 38
Refer to the exhibit.
An OT network security audit concluded that the application sensor requires changes to ensure the correct security action is committed against the overrides filters.
Which change must the OT network administrator make?
- A. Set the priority of the C.BO.NA.1 signature override to 1.
- B. Change the security action of the industrial category to monitor.
- C. Remove IEC.60870.5.104 Information.Transfer from the first filter override.
- D. Set all application categories to apply default actions.
Answer: A
Explanation:
Explanation
According to the Fortinet NSE 7 - OT Security 6.4 exam guide1, the application sensor settings allow you to configure the security action for each application category andnetwork protocol override. The security action determines how the FortiGate unit handles traffic that matches the application category or network protocol override. The security action can be one of the following:
Allow: The FortiGate unit allows the traffic without any further inspection.
Monitor: The FortiGate unit allows the traffic and logs it for monitoring purposes.
Block: The FortiGate unit blocks the traffic and logs it as an attack.
The priority of the network protocol override determines the order in which the FortiGate unit applies the security action to the traffic. The lower the priority number, the higher the priority. For example, a priority of 1 is higher than a priority of 10.
In the exhibit, the application sensor has the following settings:
The industrial category has a security action of allow, which means that the FortiGate unit will not inspect or log any traffic that belongs to this category.
The IEC.60870.5.104 Information.Transfer network protocol override has a security action of block, which means that the FortiGate unit will block and log any traffic that matches this protocol.
The IEC.60870.5.104 Control.Functions network protocol override has a security action of monitor, which means that the FortiGate unit will allow and log any traffic that matches this protocol.
The IEC.60870.5.104 Start/Stop network protocol override has a security action of allow, which means that the FortiGate unit will not inspect or log any traffic that matches this protocol.
The IEC.60870.5.104 Transfer.C.BO.NA.1 network protocol override has a security action of block, which means that the FortiGate unit will block and log any traffic that matches this protocol.
The problem with these settings is that the IEC.60870.5.104 Transfer.C.BO.NA.1 network protocol override has a lower priority than the IEC.60870.5.104 Information.Transfer network protocol override. This means that if the traffic matches both protocols, the FortiGate unit will apply the security action of the higher priority override, which is block. However, the IEC.60870.5.104 Transfer.C.BO.NA.1 protocol is used to transfer binary outputs, which are essential for controlling OT devices. Therefore, blocking this protocol could have negative consequences for the OT network.
To fix this issue, the OT network administrator must set the priority of the IEC.60870.5.104 Transfer.C.BO.NA.1 network protocol override to 1, which is higher than the priority of the IEC.60870.5.104 Information.Transfer network protocol override. This way, the FortiGate unit will apply the security action of the lower priority override, which is allow, to the traffic that matches both protocols. This will ensure that the FortiGate unit does not block the traffic that is used to transfer binary outputs, while still blocking the traffic that is used to transfer information.
