FortiGate OT Security

Question

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 protocols from PLCs. Which security sensor must you implement to detect protocols on the OT network?

Options

  • AIntrusion prevention system (IPS)
  • BDeep packet inspection (DPI)
  • CAntivirus inspection
  • DApplication control (AC)

Explanation

The FortiGuard Operational Technology (OT) Security Service for FortiGate combines IPS and application control signatures tailored to OT environments, enabling detection and protection of OT-specific protocols and threats. IPS is essential for detecting network-level threats and protocols associated with OT devices Deep packet inspection (DPI) is part of the traffic analysis process but the primary sensor for detecting specific OT protocols is IPS. Antivirus and application control are generally less focused on protocol detection for OT networks compared to IPS.
