✎ Lesson 4.5 Quiz
Question 1 of 5 A manufacturing plant operates 300 industrial controllers that CANNOT be patched (vendor abandoned firmware support; regulatory certification blocks replacement for three more years). Which single defensive control provides the BEST risk reduction during that three-year window?
Question 2 of 5 A vendor selling IoT sensors to U.S. federal agencies must meet specific NIST security requirements: no hardcoded default passwords, support for receiving patches, and a documented coordinated-vulnerability-disclosure process. Which piece of U.S. legislation imposes these requirements?
Question 3 of 5 Consider the following statements about IoT and embedded security.
I. Many IoT devices cannot run traditional antivirus because they lack sufficient CPU and memory.
II. All industrial controllers are replaced every two years, so old firmware is rarely a concern.
III. Placing unpatchable devices on the same VLAN as user workstations is a recommended defense.
Which of the statements is TRUE?
Question 4 of 5 An IoT device manufacturer wants to prevent any tampered or unsigned firmware from running, even if an attacker gains physical access and swaps the flash storage. The bootloader must cryptographically verify each stage before transferring control. Which technology BEST describes this design?
Question 5 of 5 A security auditor asks a manufacturing firm to produce an authoritative list showing every IoT device in the organization, along with each device’s firmware version, owner, network segment, and planned replacement date. The firm cannot. Which fundamental IoT security practice is missing?
