Your organization operates critical infrastructure and industrial control systems (ICS) that are vital for national security. As a cybersecurity architect, you are tasked with evaluating solutions for securing these systems against sophisticated threats. The solution must comply with industry standards, provide real-time monitoring, and be scalable across multiple sites. Which of the following solutions would BEST meet these requirements? (Choose one option)
A
Deploy a traditional antivirus solution across all devices, assuming it will suffice for OT and ICS environments due to its widespread use in IT environments.
B
Implement a dedicated security solution like Microsoft Defender for IoT, which is specifically designed for OT and ICS environments, offering advanced threat detection and compliance with industry standards.
C
Rely on the built-in security features of OT and ICS devices, considering them adequate for protection against modern cyber threats.
D
Focus exclusively on enhancing the network perimeter security, under the assumption that internal threats are negligible.
