Question 9

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?

Options:

A.

Configure outbound security policies with limited active authentication users of the third-party company.

B.

Create VPN tunnels between downstream FortiGate devices and the edge FortiGate to protect ICS network traffic.

C.

Split the edge FortiGate device into multiple logical devices to allocate an independent VDOM for the third-party company.

D.

Implement an additional firewall using an additional upstream link to the internet.

Question 10

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.

Options:

A.

Configure a fabric connector with a notification policy on FortiSIEM to connect with FortiGate.

B.

Create a notification policy and define a script/remediation on FortiSIEM.

C.

Define a script/remediation on FortiManager and enable a notification rule on FortiSIEM.

D.

Deploy a mitigation script on Active Directory and create a notification policy on FortiSIEM.

Question 11
