The two benefits of a Nozomi integration with FortiNAC are enhanced point of connection details and importation and classification of hosts. Enhanced point of connection details allows for the identification and separation of traffic from multiple points of connection, such as Wi-Fi, wired, cellular, and VPN. Importation and classification of hosts allows for the automated importing and classification of host and device information into FortiNAC. This allows for better visibility and control of the network.

B. NIST Cybersecurity Framework (CSF)

Role: Provides a risk-based approach to manage cybersecurity for critical infrastructure (including ICS/SCADA/DCS).

Fortinet Reference:

Fortinet OT Security Solution Guide (v7.2):

"The NIST Cybersecurity Framework is widely adopted in OT environments to align security practices with business objectives, manage risks, and ensure resilience."

Page 12: "Framework adoption (e.g., NIST CSF) helps organizations prioritize OT asset protection."

C. IEC 62443

Role: International standard specifically designed for ICS/OT security, covering technical controls, processes, and risk management.

Fortinet Reference:

*Fortinet NSE 7 - OT Security 7.2 Study Guide*:

"IEC 62443 is the foundational standard for securing industrial automation and control systems (IACS), including SCADA and DCS. It defines security zones, conduits, and security levels (SLT)."

*Module 4: "IEC 62443 provides OT-specific security requirements not covered by IT frameworks."*

Why Other Options Are Incorrect

A. Modbus: A communication protocol (not a framework) used in OT environments. It lacks security features and governance.

FortiGate OT Security Guide:

"Modbus is an unauthenticated, cleartext protocol vulnerable to eavesdropping. It is not a security framework."

D. IEC 104: A telecontrol protocol for SCADA (based on IEC 60870-5-104). It is not a security framework.

FortiSIEM OT Monitoring Handbook:

"IEC 104 is used for data transmission in electrical grids. Like Modbus, it requires external security controls."

Key Documentation Extracts

Fortinet OT Security Solution Guide (v7.2):

*"Industrial environments align with IEC 62443 for OT-specific controls and NIST CSF for risk governance. Protocols like Modbus/IEC 104 require additional hardening."*

NSE 7 OT Security 7.2 Curriculum:

"IEC 62443 addresses OT asset discovery, segmentation, and threat detection. NIST CSF complements it with risk assessment methodologies."
