You are a cybersecurity consultant at SecureIoT Inc. A manufacturing company has contracted you to strengthen the security of their Industrial IoT (IIoT) devices used in their operational technology…

Increasing password change frequency is a good practice but is insufficient alone to provide comprehensive protection against advanced threats targeting IIoT devices or to segment the network effectively.

Using the same encryption standards for IIoT and IT devices might not be appropriate due to the often resource-constrained nature of IIoT devices and does not address network isolation or attack containment.

Relying on an existing firewall and installing antivirus software on IIoT devices (if even possible) is often inadequate for an OT environment, as traditional IT security tools may not be compatible or effective, and it doesn't address the need for network isolation.

Implementing network segmentation separates IIoT devices and the OT network from the broader IT network and other less critical segments. This strategy creates distinct security zones, limiting lateral movement for attackers, containing potential compromises to specific areas, and preventing attacks on IT systems from disrupting critical OT operations and safety.
