An OT network consists of multiple FortiGate devices. The edge FortiGate device is deployed as the secure gateway and is only allowing remote operators to access the ICS networks on site. Management hires a third-party company to conduct health and safety on site. The third-party company must have outbound access to external resources. As the OT network administrator, what is the best scenario to provide external access to the third-party company while continuing to secure the ICS networks?
Refer to the exhibit. You are assigned to implement a remote authentication server in the OT network. Which part of the hierarchy should the authentication server be part of?
To increase security protection in an OT network, how does application control on ForliGate detect industrial traffic?
As an OT administrator, it is important to understand how industrial protocols work in an OT network. Which communication method is used by the Modbus protocol?
An OT architect has deployed a Layer 2 switch in the OT network at Level 1 the Purdue model-process control. The purpose of the Layer 2 switch is to segment traffic between PLC1 and PLC2 with two VLANs. All the traffic between PLC1 and PLC2 must first flow through the Layer 2 switch and then through the FortiGate device in the Level 2 supervisory control network. What statement about the traffic between PLC1 and PLC2 is true?
An OT administrator is defining an incident notification policy using FortiSIEM and would like to configure the system with a notification policy. If an incident occurs, the administrator would like to be able to intervene and block an IP address or disable a user in Active Directory from FortiSIEM. Which step must the administrator take to achieve this task?
With the limit of using one firewall device, the administrator enables multi-VDOM on FortiGate to provide independent multiple security domains to each ICS network. Which statement ensures security protection is in place for all ICS networks?
Which three common breach points can be found in a typical OT environment? (Choose three.)
As an OT network administrator, you are managing three FortiGate devices that each protect different levels on the Purdue model. To increase traffic visibility, you are required to implement additional security measures to detect exploits that affect PLCs. Which security sensor must implement to detect these types of industrial exploits?
Refer to the exhibit. An OT architect has implemented a Modbus TCP with a simulation server Conpot to identify and control the Modus traffic in the OT network. The FortiGate-Edge device is configured with a software switch interface ssw-01. Based on the topology shown in the exhibit, which two statements about the successful simulation of traffic between client and server are true? (Choose two.)

An OT architect has deployed a Layer 2 switch in the OT network at Level 1 the Purdue model-process control. The purpose of the Layer 2 switch is to segment traffic between PLC1 and PLC2 with two VLANs. All the traffic between PLC1 and PLC2 must first flow through the Layer 2 switch and then through the FortiGate device in the Level 2 supervisory control network.

What statement about the traffic between PLC1 and PLC2 is true?

A.
The Layer 2 switch rewrites VLAN tags before sending traffic to the FortiGate device.
Answers
A.
The Layer 2 switch rewrites VLAN tags before sending traffic to the FortiGate device.
B.
The Layer 2 switches routes any traffic to the FortiGate device through an Ethernet link.
Answers
B.
The Layer 2 switches routes any traffic to the FortiGate device through an Ethernet link.
C.
PLC1 and PLC2 traffic must flow through the Layer-2 switch trunk link to the FortiGate device.
Answers
C.
PLC1 and PLC2 traffic must flow through the Layer-2 switch trunk link to the FortiGate device.
D.
In order to communicate, PLC1 must be in the same VLAN as PLC2.
Answers
D.
In order to communicate, PLC1 must be in the same VLAN as PLC2.
Suggested answer: C

Explanation:

The statement that is true about the traffic between PLC1 and PLC2 is that PLC1 and PLC2 traffic must flow through the Layer-2 switch trunk link to the FortiGate device.
